Division of the State Architect
1701A.4 Special inspections and tests
Added reference to Chapters 14, 15 and 24 to the list of chapters with special inspection and test requirements to account for those in the noted chapters.

Removed the specific reference pointer to the California Administrative Code (CAC) since many different sections specify special inspection, test, and observation requirements and a comprehensive listing is not needed. 1704A.3 Statement of special inspections
Added language to not permit the exception that allows non-licensed individuals to prepare a statement of special inspections. The California Education Code Section 17302 requires designs of school projects by design professionals. 1704A.4 Contractor responsibility
DSA's construction oversight and quality assurance programs render requirements for the contractor to submit a statement of responsibility unnecessary for most projects. Therefore, only when such a requirement is specified on the approved construction documents does it apply.
1705A.2.1 Structural steel
Clarified prohibition of quality assurance aspects (rather than all aspects, such as quality control) for AISC 360, Chapter N, N5 Item 2 (Quality Assurance), N5 Item 4 (Inspection of Welding), and N7 (Nonconforming Material and Workmanship).

2025 Summary of California Code Changes 29
Added a note clarifying that additions to other reference standards in Table 1705A.2.1 apply when those provisions are applicable.

Clarified intent of replacing language in AISC 360, Section N5.5(b) and through formatting for consistency with modification of model reference standards used in other amendments.

DSA considered deleting non-adoption of some AISC 360 Chapter N references as well as the reference to Table 1705A.2.1. However, based on early feedback from various welding special inspectors and material testing laboratory managers, confusion regarding expectations caused by the terms “observe,” “perform,” and “document” not correlating with periodic or continuous inspection, DSA decided to maintain those.

Table 1705A.2.1 Required special inspections and tests of steel construction Added and updated pointers to referenced standards (such as AISC 341, 358, or 370 and AISI S100 or S240) and CBC sections (such as 2201A.2, 1705A.8). Other specific items resulting in regulatory changes:

Item 3. – Removing the word "deck" such that material identification applies to all structural cold-formed steel, not just decks.

Item 5.a. – Removing the word "deck" such that welding inspection requirements apply to all structural cold-formed steel, not just decks.

DSA considered deleting Table 1705A.2.1. However, based on early feedback from various welding special inspectors and material testing laboratory managers, confusion regarding expectations due to the terms “observe,” “perform,” and “document” not correlating with periodic or continuous inspection, DSA decided to maintain the table.
1705A.2.3 Cold-formed steel deck
Modifications prohibit certain reference standard provisions while explicitly referencing Table 1705A.2.1 to achieve consistency with similar existing and new amendments in Section 1705A.2.1.

CALIFORNIA ENERGY CODE – PART 6
Please visit the California Energy Commission’s website for Part 6 updates. energy.ca.gov/programs-and-topics/programs/building-energy-efficiencystandards/online-resource-center/overview CALIFORNIA WILDLAND-URBAN INTERFACE CODE – PART 7
Overview
The new California Wildland-Urban Interface Code (CWUIC), based on the International Wildland-Urban Interface Code, was created by relocating chapters, sections and language from several parts of Title 24, including the California Building Code (Chapter 7A), California Residential Code (Section R337) and the California Fire Code (Chapter 49). Additionally, it incorporates other provisions from Title 24 (not relocated), and sections from Title 14 (Natural Resources) and Title 19 (Public Safety) of the California Code of regulations, and sections from the Government Code, the Health and Safety Code, and Public Resources Code.

Section H107, Cross Reference Tool, was added to Appendix H of the CWUIC. It lists each section of the code and identifies the source document and section for each provision.

As part of the effort to consolidate language from the multiple areas of law and regulations, a reasonable amount of “clean-up” was made before codifying the language into the CWUIC. This consisted of clarifying intent, correcting minor errors from previous code cycles, and reorganizing sections to align with model code.

Members of the City Council
SUBJECT: First Read and Introduction of an Ordinance of the City Council of the City of Fountain Valley, California, amending Chapter 14.17 of the Fountain Valley Municipal Code pertaining to the Cross-Connection Control Program to be consistent with the City’s Cross-Connection Control Management Plan and the State Water Resources Control Board’s Cross-Connection Control Policy Handbook
Three-Year Strategic Goals
☐ Enhance the culture and environment of “A Nice Place to Live.” ☐ Achieve fiscal stability by evaluating processes, and attract and retain revenue producing businesses/opportunities.
☐ Attract and retain quality staff through best practices and trends. ☐ Maintain, build, and modernize infrastructure to support the growth and future needs of the City.
☒ Not applicable.

EXECUTIVE SUMMARY
The State Water Resources Control Board’s (State Water Board’s) Cross-Connection Control Policy Handbook (CCCPH), which took effect July 1, 2024, requires all public water systems to develop a written cross-connection control program. In order to comply with the requirements of the CCCPH, the City prepared the 2025 Cross-Connection Control Management Plan (CCCMP), which was submitted to the State Water Board for review by the July 1, 2025, deadline. The City’s CCCMP is attached for reference only. It is considered a living document that will be enforced and modified administratively as needed to protect the water supply and comply with state regulations.

City staff requests that the City Council amend Chapter 14.17 of the Fountain Valley Municipal Code (FVMC) pertaining to the Cross-Connection Control Program to be consistent with the City’s CCCMP and the State Water Board’s CCCPH.

The purpose of FVMC 14.17, the City’s 2025 CCCMP, and the State Water Board’s CCCPH is to establish rules, regulations, and procedures to protect the public drinking water supply from contaminants caused by cross-connection or potential cross-connection.

Ordinance Amending FVMC Chapter 14.17 – Cross-Connection Control Program October 23, 2025

DISCUSSION
On February 6, 1996, the City Council adopted Ordinance No. 1247 to repeal Section 14.

16.080 and add Chapter 14.17 – Cross-Connection Control Program to the Fountain Valley Municipal Code in compliance with State of California Administrative Code, Title 17, revisions pertaining to cross-connection regulations.

Effective July 1, 2024, the State Water Board’s CCCPH replaced the State of California Administrative Code, Title 17, California Code of Regulations, Sections 7583 through 7605.

The CCCPH is designed to meet the requirements of the California Health and Safety Code and applies to all public water systems statewide. It aligns with recent legislative updates, including Assembly Bills 1671 and 1180, which amended key provisions of the California Safe Drinking Water Act and Water Code to require enhanced and consistent backflow prevention standards statewide. The CCCPH reflects current best practices in cross-connection control and establishes an updated regulatory framework for public water systems.

All California public water systems must comply with the requirements of the CCCPH, including the implementation and enforcement of a written cross-connection control program to protect the public water supply.

To develop a written cross-connection control program in compliance with the requirements of the CCCPH, the City participated in a collaborative work group of 26 agencies in Orange County, including the State Water Board. This work group, with the assistance of John Robinson Consulting, played a crucial role in the development of the City’s 2025 CCCMP.

CCCMP Key Elements
The City’s 2025 CCCMP includes the following key elements:
 Hazard Assessments and Required Protection: Evaluation and documentation of services based on their level of hazard, which will require dedicated staff time and resources to carry out effectively.
 Backflow Prevention Requirements: Outlines the standards and criteria for installing and maintaining backflow prevention assemblies.
 Certified Backflow Prevention Assembly Testers and Specialists: Describes the certification requirements for testers and specialists involved in the program.  Incident Response and Reporting: Procedures for responding to and reporting backflow incidents.
 Recordkeeping: Maintain detailed tracking of hazard assessments, backflow prevention installations, tests, and enforcement actions.
 Public Outreach and Education: Implement awareness to educate targeted customers about backflow risks and their compliance responsibilities.

Ordinance Amending FVMC Chapter 14.17 – Cross-Connection Control Program October 23, 2025

The City’s 2025 CCCMP was submitted to the State Water Board for review by the July 1, 2025, deadline in compliance with the requirements of the CCCPH and is attached for reference only. The City’s CCCMP is a living document that will be enforced and modified administratively as needed to protect the water supply and comply with state regulations.

City staff is recommending that Chapter 14.17 of the Fountain Valley Municipal Code (FVMC) pertaining to the Cross-Connection Control Program be amended to comply with current and future revisions of the CCCPH, as related to the rules and regulations for cross-connection control programs, and the City’s CCCMP.

City staff will use the rules, regulations, and procedures documented in the CCCMP and amended FVMC Chapter 14.17 to protect the City’s drinking water supply from contaminants caused by cross-connection or potential cross-connection.

FISCAL REVIEW
The proposed Ordinance has no direct financial impacts.

PUBLIC NOTIFICATION
A public notice of the time and place of said ordinance adoption has been published in the Orange County Register on October 2, 2025.

ENVIRONMENTAL IMPACT REVIEW
Not applicable.

ATTORNEY REVIEW
The Attorney for the City has reviewed and approved the subject ordinance.

ALTERNATIVES
Alternative No.1: Introduce and Approve for the Second Reading an Ordinance of the City Council of the City of Fountain Valley, California, amending Chapter 14.17 of the Fountain Valley Municipal Code pertaining to the Cross-Connection Control Program to be consistent with the City’s Cross-Connection Control Management Plan and the State Water Resources Control Board’s CrossConnection Control Policy Handbook. This is the recommended action.

Alternative No.2: Introduce and Do Not Approve for the Second Reading an Ordinance of the City Council of the City of Fountain Valley, California, amending Chapter 14.17 of the Fountain Valley Municipal Code.

CHAPTER 14.17

CROSS-CONNECTION CONTROL PROGRAM

14.17.010. PURPOSE.

In cooperation with the State Water Resources Control Board Division of Drinking Water, the City’s primary goal is to ensure the distribution of a safe and potable water supply to all domestic water users. In order for the City to achieve this goal, a Cross-Connection Control Management Plan has been developed with an effective date of July 1, 2025. The City’s Cross-Connection Control Management Plan was developed pursuant to the requirements set forth in the Cross-Connection Control Policy Handbook issued by the State Water Resources Control Board.

In accordance with standards established in the California Administrative CodeCrossConnection Control Policy Handbook, as administered by the water superintendent, approved backflow prevention devices shall be installed to protect the public water supply system from contamination due to potential and actual cross-connections. Prevention of cross-connections include: (1) isolating, within the premises, contamination that may occur because of some undiscovered or unauthorized cross-connection on the premises; (2) eliminating existing connections between drinking water systems and other sources of water that are not approved as safe and potable for human consumption; (3) eliminating cross-connections between drinking water systems and sources of contamination; (4) safeguarding against cross-connections in the future. This shall be accomplished by the establishment of a cross-connection control program as required by state regulations. The ordinance codified in this chapter is adopted pursuant to the State of California Administrative Code, Title 17, of the California Code of Regulations, "Regulations Relating to Cross-Connections”Cross-Connection Control Policy Handbook which replaced State of California Administrative Code, Title 17, California Code of Regulations, Sections 7583 through 7605, and applies to all State of California Public Water Systems, as defined in California’s Health and Safety Code (CHSC, section 116275(h)), hereinafter referred to as the "state regulations."

14.17.020. APPLICATION.

This chapter shall be interpreted so as to comply with the state regulations on crossconnections as the same exist now, or as subsequently amended. The definitions set forth therein are adopted, except as otherwise provided.

14.17.030. ADMINISTRATION.

The cross-connection control program shall be administered by the water department's cross-connection control specialist under the general supervision of the water superintendent. The water department will establish and maintain a list of approved backflow prevention assemblies, as well as a list of approved backflow prevention assembly testers. The cross-connection control specialist shall conduct necessary surveys of water user premises to evaluate the degree of potential health hazards. The water department shall notify the user when an assembly needs to be tested. The user shall receive a notice containing a due date for backflow prevention assembly testing.

14.17.040. CROSS-CONNECTION PROTECTION REQUIREMENTS.

The type of protection that shall be provided to prevent backflow into the public water supply system shall be commensurate with the degree of hazard, actual or potential, that exists on the water user's premises. Unprotected cross-connections with the public water supply are prohibited. The type of backflow protection assembly that may be required includes: air-gap separation (AG), reduced pressure principle backflow protection assembly (RP), and double check valve assembly (DC). The types of backflow protection required to protect the approved water supply, at the user's water connection, to premises with varying degrees of hazard are listed in Table 1Chapter 3, Article 2.2 (3.2.2) of the state regulations. Situations which are not covered in Table 1Chapter 3, Article 2.2 (3.2.2) shall be evaluated on a case-by-case basis and the appropriate backflow protection shall be determined by the water superintendent in accordance with the nature of the hazard presented.

14.17.050. BACKFLOW PREVENTION ASSEMBLIES.
(a) Only backflow prevention assemblies which have been approved by the water department, in accordance with the state regulations, shall be acceptable for installation by a water user. A list of approved backflow prevention assemblies will be provided upon request. Backflow prevention assemblies shall be installed in a manner prescribed in the state regulations. Location of the assemblies shall be as close as practical to the user's connection. The water superintendent shall have the final authority in determining the required location of a backflow prevention assembly.

Upon installation, backflow prevention assemblies shall be tested by an Orange County health departmentAmerican Water Works Association certified backflow tester.
(b) Testing of backflow assemblies shall be conducted only by an Orange County health departmentAmerican Water Works Association certified backflow tester that

possesses a current Ccity of Fountain Valley business license. Backflow prevention assemblies must be tested immediately after installation, relocation or repair.

Approval must be obtained from the water department prior to removing, relocating or replacing a backflow prevention assembly.
(c) As a minimum, backflow prevention assemblies other than single-family residential irrigation systems, as well as other applications using atmospheric vacuum breakers, must be tested annually. More frequent testing may be required if deemed necessary by the water superintendent, based on facts demonstrating a potential hazard. No assembly shall be placed back in service unless it is functioning as required. These assemblies shall be serviced, overhauled or replaced, whenever they are found to be defective. All costs of testing, repair and maintenance shall be borne by the water user.

14.17.060. INSPECTION FEE.

When a new backflow prevention assembly is installed or an existing backflow prevention assembly relocated, an installation inspection shall be completed by the water department. The installation inspection shall be conducted by the water department's cross-connection control specialist at the expense of the water user. The inspection fee, established by separate resolution, shall be paid by the water user prior to acquisition of water service. On single-family residential irrigation systems, as well as other applications where atmospheric vacuum breakers are considered appropriate backflow protection, no tests, inspections or fees shall apply.

14.17.070. WATER SERVICE TERMINATION.

When the water department encounters water uses that represent a hazard to the potable water supply that cannot be immediately abated by other means, the procedure for terminating water service shall be instituted. Conditions or water uses that create a basis for termination of water service shall include, but are not limited to the following:
(1) Refusal to install or to test a backflow prevention assembly, or to repair or replace a faulty backflow prevention assembly;
(2) Direct or indirect connection between the public water system and a sewer connection;
(3) Unprotected, direct or indirect, connection between the public water system and a system or equipment containing contaminants;
(4) Unprotected, direct or indirect, connection between the public water system and an auxiliary water system.

Unless immediate action is required because of an urgent health and safety problem, the water department will terminate service to a water user's premises after proper notification of violation has been sent. If no action has been taken the user fails to correct the violation within the allowed period, water service may be terminated, locked service valves installed, and service shall not be restored until corrections have been made, all provisions of this code met, and the public health, safety and welfare ensured. In cases

in which immediate termination is required because of an urgent health and safety problem, service may be immediately terminated. The conditions constituting the urgent health and safety problem should be promptly documented.

14.17.080. VIOLATIONS.

It is unlawful for any person, firm or corporation, at any time, to make or maintain, or cause to be made or maintained, temporarily or permanently, for any period of time whatsoever, any cross-connection between plumbing pipes or water fixtures being served with water by the city water department, and any other source of water supply, or to maintain any sanitary fixture or other appurtenances or fixtures which, by reason of their construction, may cause or allow backflow of water, or other substances, into the water supply system of the city, and/or the service of water pipes or fixtures of any consumer of the city, or to fail to comply with the provisions of this chapter. Violations shall be punished as provided in Chapter 1.16 of this code.

SECTION 2:

If any section, subsection, sentence, clause, or phrase of this ordinance is for any reason held to be invalid or unconstitutional by a decision of any court of competent jurisdiction, such decision shall not affect the validity of the remaining portions of the ordinance. The City Council declares that it would have passed this ordinance and each and every section, subsection, sentence, clause, or phrase not declared invalid or unconstitutional without regard to whether any portion of the ordinance would subsequently be declared invalid or unconstitutional.

SECTION 3:

The City Clerk shall certify to the adoption of this Ordinance and cause it to be published as required by law. This ordinance shall become effective thirty (30) days after the date of its adoption.

City of Fountain Valley Cross Connection Control Management Plan (CCCMP City of Fountain Valley Beach CCCMP – June 2025 1-1
1 Cross Connection Control Policy Overview

1.1 Objective
The primary objective of the Cross-Connection Control Management Plan (CCCMP) is to bring the City into compliance with the Cross Connection Control Policy Handbook (CCCPH) developed by the State Water Resources Control Board (State Water Board) for the protection of public health through the establishment of standards intended to ensure a public water system’s (PWS) drinking water distribution system will not be subject to the backflow of liquids, gases, or other substances, see CCCMP Appendix A. In addition, by providing basic educational information on backflow prevention, the City intends to build a foundation of awareness within the City regarding the importance of backflow protection and cross-connection control, leading to the implementation of a robust cross-connection control program.

Per Section 3.1.4 (b)(1) description the City will implement the requirements of the State CCCPH by implementing ordinances and procedures as detailed in this CCCMP.

1.2 Applicability
The State CCCPH and its standards apply to all California PWSs, as defined in California’s Health and Safety Code (CHSC, section 116275 (h)). Compliance with the State CCCPH is mandatory for all California PWSs. The City’s CCCMP has been developed in conformance to the State CCCPH and is applicable to all customers within the City’s service area.

1.3 Policy Development Background and Legal Authorities Through the adoption of the State CCCPH, the State Water Board exercised its authority, under California’s Safe Drinking Water Act (SDWA), to establish enforceable standards applicable to California’s PWSs. Failure to comply with the CCCMP which is in conformance with the State CCCPH may result in the issuance of compliance, enforcement, or other corrective actions against the City.

1.4 California Safe Drinking Water Act
On October 6, 2017, Assembly Bill 1671 (AB 1671) was approved and filed with the Secretary of State (see CCCMP Appendix B). AB 1671 amended California’s SDWA through the establishment of CHSC sections 116407 and 116555.5. AB 1671 also amended section 116810 of the CHSC, which is briefly discussed in CCCPH.

On October 2, 2019, Assembly Bill 1180 (AB 1180) was approved and filed with the Secretary

City of Fountain Valley Cross Connection Control Management Plan (CCCMP) City of Fountain Valley CCCMP – June 2025 1-2
of State. AB 1180 amended Section 116407 of the CHSC and added section 13521.2 to the Water Code. AB 1180 requires that the CCCPH include provisions for the use of a swivel or changeover device (swivel-ell), see CCCMP Appendix B.

Pursuant to sections 116407 and 116555.5 of the CHSC, the State Water Board chose to adopt standards for backflow protection and cross-connection control through the adoption of this State CCCPH, which became effective July 1, 2024.
• The State Water Board is required to adopt regulations for the control of crossconnections that it determines to be necessary for ensuring PWSs “distribute a reliable and adequate supply of pure, wholesome, potable, and healthy water.” (CHSC section 116375, subd. (c).)
• Any person who owns a PWS is required to ensure that the distribution system will not be subject to backflow under normal operating conditions. (CHSC section 116555, subd. (a)(2).)
Prior to AB 1671 and the adoption of the State CCCPH, California’s regulations pertaining to cross-connection control were set forth in regulations in CCR Title 17, which were adopted in 1987 with minor revisions in 2000. Although still protective to public health, the CCR Title 17 cross-connection regulations required updating as both the drinking water and cross-connection control industries had evolved. This State CCCPH updates those regulations, which as previously noted are no longer operative following the adoption of the State CCCPH.

The State Water Board may update its standards for backflow protection and cross- connection control through revisions of the State CCCPH. Prior to adopting substantive revisions to the State CCCPH, the State Water Board will consult with state and local agencies and persons identified as having expertise on the subject by the State Water Board, and the State Water Board will hold at least one public hearing to consider public comments.

2 Hazard Assessments and Required Protection
In accordance with the State CCCPH, Section 3.1.3 (a)(3) – Hazard Assessments, Section 3.1.4 (b)(2), and Section 3.2.1 – The City must survey its service area and conduct hazard assessments per Article 2 of the State CCCPH that identifies actual or potential cross-connection hazards, degree of hazard, and any backflow protection needed.

2.1 Hazard Assessments
a. To evaluate the potential for backflow into the City’s water distribution system the City must conduct an initial hazard assessment of the user premises within its service area.

The hazard assessment must consider:

1. The existence of cross-connections;

2. the type and use of materials handled and present, or likely to be, on the user premises;

3. the degree of piping system complexity and accessibility;

4. access to auxiliary water supplies, pumping systems, or pressure systems;

5. distribution system conditions that increase the likelihood of a backflow event (e.g., hydraulic gradient differences impacted by main breaks and high water- demand situations, multiple service connections that may result in flow-through conditions, etc.);

6. user premises accessibility;

7. any previous backflow incidents on the user premises; and

8. the requirements and information provided in the State CCCPH, and the City’s CCCMP.
b. Each hazard assessment must identify the degree of hazard to the City’s distribution system as either a high hazard cross-connection, a low hazard cross- connection, or having no hazard. Examples of some high hazard cross-connection activities may be found in CCCMP Appendix E.
c. The hazard assessment must determine whether an existing BPA, if any, provides adequate protection based on the degree of hazard.
d. Hazard assessments completed prior to the adoption of the State CCCPH may be considered as an initial hazard assessment provided that such hazard assessments and associated backflow protection provide protection consistent with the State CCCPH and the City describes their review of these assessments in the City’s CCCMP. e. Subsequent to the initial hazard assessment described in subsection (a), the City must perform a hazard assessment under the following criteria:

1. if a user premises changes account holder, excluding single-family residences;

2. if a user premises is connected to the City’s water distribution system;

City of Fountain Valley Cross Connection Control Management Plan (CCCMP) City of Fountain Valley CCCMP – June 2025 2-2

3. if evidence exists of changes in the activities or materials on a user’s premises;

4. if backflow from a user’s premises occurs;

5. periodically, as identified in the City’s CCCMP required pursuant to State CCCPH section 3.1.4.;

6. if the State Water Board requests a hazard assessment of a user’s premises; or

7. if the City concludes an existing hazard assessment may no longer accurately represent the degree of hazard.
f. A cross-connection control specialist must review or conduct each initial and follow-up hazard assessment pursuant to this section and make a written finding that, in the specialist’s judgment based on cross-connection control principles, the City’s hazard assessment properly identified all hazards at the time of the assessment, the appropriate degree of hazards, and the corresponding backflow protection.

2.2 Hazard Assessment Process
In order to assess each connection in the City’s water distribution system for potential cross connection the City will undertake assessments in the following phases. As part of the hazard assessment process the City has created a tracking system for the assessments made under the CCCMP. See CCCMP Appendix F. Data will be gathered and logged into the assessment database in three phases. The assessment database will be maintained per the procedures outlined in Section 9.
• Phase 1 - All connections with existing backflow prevention assemblies at the meter connection
• Phase 2 - All Commercial/Industrial/Institutional connections without backflow prevention assemblies at the meter connection
• Phase 3 – Residential connections without backflow prevention assemblies at the meter connection

2.2.1 Phase 1 - Connections with Backflow Protection
The City currently has 1,106 connections with an approved BPA installed at the meter as of 6/6/25. For connections with backflow protection the City will enter each address into the assessment tracking system indicating what type of BPA has been installed. The City’s Cross Connection Control Specialist will review the data when entered into the assessment database to verify that an appropriate BPA has been installed on the meter connection. The Cross Connection Control Specialist’s review date will be noted in the assessment database.

It is assumed that a Cross Connection Control Specialist can process (3) existing connections with backflow protection installed at the meter per available hour, and the total number of annual Cross Connection Control Specialist available hours is 93 hrs./yr (5% of total annual 1,867 hrs., based 2,080 hrs./yr less 80 hrs./yr for vacation, 45 hrs./yr for sick leave, and 88 hrs./yr for holidays) for a total of 279 existing connections per year per Cross Connection Control Specialist assigned by the City to cross connection control.

Based on the availability of the Cross Connection Control Project Specialist the City has

City of Fountain Valley Cross Connection Control Management Plan (CCCMP) City of Fountain Valley CCCMP – June 2025 2-3
determined that this phase of the assessments can be completed within 4 years from the adoption of the City’s CCCMP.

2.2.2 Phase 2 - Commercial/Industrial/Institutional Connections without Backflow Protection
The City currently has 350 CII connections without backflow protection installed at the meter as of 6/6/25. For those CII connections without an approved BPA at the meter connection the City will provide a self-reporting letter to provide information regarding onsite conditions which would necessitate the installation of an approved BPA at the meter connection. The self-reporting letters will be distributed via direct mail.

The self-reporting letters would be reviewed based on the available Cross Connection Control Specialist hours. It is assumed that a Cross Connection Control Specialist can process (3) existing connections without backflow protection installed at the meter per available hour, and the total number of annual Cross Connection Control Specialist available hours is 93 hrs./yr (5% of total annual 1,867 hrs., based 2,080 hrs./yr less 80 hrs./yr for vacation, 45 hrs./yr for sick leave, and 88 hrs./yr for holidays) for a total of 279 existing connections per year per Cross Connection Control Specialist assigned by the City to cross connection control.

• If the Cross Connection Control Specialist determines that based on the self-reporting letter that an approved BPA is not required, they will note that in the assessment database and the reason for not requiring an approved BPA.
• If the Cross Connection Control Specialist determines that based on the self-reporting letter that an approved BPA is required, they will note that in the assessment database and notify the commercial/industrial customer that an approved BPA must be installed at the meter connection and note that determination in the assessment database.

The City has determined that this phase of the assessments can be completed within one year and 3 months from the completion of Phase 1.

2.2.3 Phase 3 – Residential Connections without Backflow Protection The City currently has 12,964 residential connections without backflow protection installed at the meter as of 6/6/25. For those residential connections the City will assess each site by means of office-based tools such as:
• Reviewing sites via Google Maps or other aerial photography software • Reviewing tract maps to review blocks of residential customer in a common building area or zone.
• Using meter route maps or other billing information databases.

The office-based assessment will review sites for:

City of Fountain Valley Cross Connection Control Management Plan (CCCMP) City of Fountain Valley CCCMP – June 2025 2-4
• Private water wells
• Other auxiliary water supplies
• Sewer lift stations
• Graywater systems
The office-based assessments would be conducted based on the available Cross Connection Control Specialist hours to review the office-based assessments and/or files. • If the Cross Connection Control Specialist determines that based on the office-based assessment that an approved BPA is not required, they will note that in the assessment database.
• If the Cross Connection Control Specialist determines that based on the office-based that an approved BPA is required, they will note that in the assessment database and notify the residential customer that an approved BPA must be installed at the meter connection and note that the customer has been contacted in the assessment database.

It is assumed that a Cross Connection Control Specialist can process (25) existing residential connections without backflow protection installed at the meter per available hour, and the total number of annual Cross Connection Control Specialist available hours is 93 hrs./yr (5% of total annual 1,867 hrs., based 2,080 hrs./yr less 80 hrs./yr for vacation, 45 hrs./yr for sick leave, and 88 hrs./yr for holidays) for a total of 2,325 existing residential connections with a BPA installed at the meter per year per Cross Connection Control Specialist assigned by the City to cross connection control.

The City has determined that this phase of the assessments can be completed within 5.6 years from the completion of Phase 2.

(B) a trained representative of the City be present to supervise each switchover; and
(C) within seven days of each switchover, if requested by the State Water Board, the City will submit a written report describing compliance with this subsection, as well as potable and recycled water usage information. (e) Except as noted below, the City must ensure its distribution system is protected with no less than DC protection for a user premises with a fire protection system within ten years of adoption of the State CCCPH.
(1) A high hazard cross-connection fire protection system, including but not limited to fire protection systems that may utilize chemical addition (e.g., wetting agents, foam, anti-freeze, corrosion inhibitor, etc.) or an auxiliary water supply, must have no less than RP protection.
(2) For existing fire protection systems that do not meet the State CCCPH, Section

3.2.2 (e)(3) or cannot install DC protection within ten years of adoption of the State CCCPH, the City may propose in the CCCMP submitted for compliance with the State CCCPH Section 3.1.4:
(A) an alternative date; or
(B) an alternative method of backflow protection that provides at least the same level of protection to public health.
(3) A BPA is not necessary for a low hazard fire protection system on a residential user premises if the following criteria are satisfied:

City of Fountain Valley Cross Connection Control Management Plan (CCCMP) City of Fountain Valley CCCMP – June 2025 4-3
(A) the user premises has only one service connection to the City; (B) a single service line onto the user premises exists that subsequently splits on the property for domestic flow and fire protection system flow, such that the fire protection system may be isolated from the rest of the user premises;
(C) a single, water industry standard, water meter is provided to measure combined domestic flow and fire protection system flow; (D)the fire protection system is constructed of piping materials certified as meeting NSF/ANSI Standard 61; and

10 User Supervisors
In accordance with the State CCCPH, Section 3.2.2 (3)(f),The State Water Board and City may, at their discretion, require a water user to designate a user supervisor when the user premises has a multi-piping system that conveys various types of fluids and where changes in the piping system are frequently made. If a user supervisor is designated the following is required:
(1) The user supervisor is responsible for the avoidance of cross-connections during the installation, operation and maintenance of the water user’s pipelines and equipment. The user supervisor must be trained on the fluids used and backflow protection for the premise, and must inform the City of changes in piping, and maintain current contact information on file with the City; and,
(2) The City must include in the CCCMP required in CCCPH Section 3.1.4 the training and qualification requirements for user supervisors if required by the State Water Board or City, identify the entity that will provide the user supervisor training, and frequency of any necessary recurring training. The training must adequately address the types of hazards and concerns typically found.

The City has not required any user supervisors for use sites within the City.

City of Fountain Valley Cross Connection Control Management Plan (CCCMP) City of Fountain Valley CCCMP – June 2025 11-1
11 Backflow Prevention Assembly Testing and Reporting
In accordance with the State CCCPH, Section 3.1.3 (a)(6) – the City must ensure that each BPA required by the CCCMP to protect the City’s domestic water system is field tested. The City must develop and implement a procedure for ensuring all BPAs are field tested, inspected, and maintained and AG’s are inspected and maintained in accordance with the State CCCPH, Section 3.3.3.

1. All BPAs installed in the City in compliance with CCCMP must be field tested following installation, repair, depressurization for winterizing, or permanent relocation. All required field testing must be performed by certified backflow prevention assembly tester.

2. BPAs must be field tested at least annually. The State CCCPH does not preclude the City, the State Water Board, or a local health agency from requiring more frequent field testing for premises with high hazard cross-connection or BPA at increased risk of testing failure.

3. Air-gap separations must be visually inspected at least annually by a certified backflow prevention assembly tester or a certified cross-connection control specialist.

4. The City must receive passing field tests before providing continuous service to a water user with a newly installed BPA.

5. BPAs that fail the field test must be repaired or replaced within 30 days of notification of the failure by the City. Extensions may be allowed at the discretion of the Cross Connection Control Specialist if mitigating circumstances warrant an extension.

Backflow prevention assembly testers must notify the City within one day if a backflow incident or an unprotected cross-connection is observed at the BPA or prior to the user premises during field testing. The City will immediately investigate and discontinue service to the user premises if a backflow incident is confirmed, and water service will not be restored to that user premises until the City receives a confirmation of a passing BPA field test from a backflow prevention assembly tester and the assembly is protecting the City.

11.1 Backflow Testing Notification Process
Each water user with a BPA on the service connection must comply with the following schedule in order to be in compliance with the CCCMP and continue to receive water service from the City.

City of Fountain Valley Cross Connection Control Management Plan (CCCMP) City of Fountain Valley CCCMP – June 2025 11-2
• First notice – the first annual notice of BPA testing required is sent to the users by mail only in one group per month for twelve months which is 45 days before the devices certification expires. The customer has 45 days from the date of the notice to respond and submit backflow test results by email.
• Second notice –if after 45 days the first notice was sent to the user test results are not submitted, a second notice will be sent to the customer by mail and email, if available.

The customer has 30 days from the date of the second notice to provide the required backflow test results by email.
• Third notice –if after 30 days after the second notice was sent to the user, a third notice will be sent to the user by mail and if available via email notifying the customer that the water will be shutoff if the backflow test results are not submitted within 15 days of the third notice.
• Fourth notice – install door hangar with one day notice to turnoff. Try to call customer and notify them that water will be shut off in three days. Example call on Monday of the second week of April for the examples above. On Thursday of that week cut off the service and notify water billing if no passing test notice has been received. Water billing will handle the reinstatement fee collection and let us know when to restore service. Do we have a door hanger that we leave when we cutoff service? If so place a notice at the address.

11.2 Damaged, missing, or improperly installed backflow prevention assemblies.

In the event that a backflow prevention assembly is missing (or stolen), installed incorrectly, illegally modified, or tampered with, the City will require that user replace or repair missing, installed incorrectly, illegally modified, or tampered BPA within 30 days of notification by the City.

Extensions may be allowed at the discretion of the Cross Connection Control Specialist if mitigating circumstances warrant an extension.

Background on Backflow Protection and Cross-Connection Control A.1 What is a Cross-Connection?
A cross-connection is an interconnection between a potable water supply and a non- potable source via any actual or potential connection or structural arrangement between a PWS and any source or distribution system containing liquid, gas, or other substances not from an approved water supply. Bypass arrangements, jumper connections, removable sections, swivel or change-over devices and other temporary or permanent devices through which, or because of which backflow can occur are considered to be cross-connections.1 The State CCCPH includes acceptable installation criteria for swivel-ell and other types of backflow prevention assemblies (BPAs) to prevent backflow.

Backflow is the undesired or unintended reversal of flow of water and/or other liquids, gases, or other substances into a PWS’s distribution system or approved water supply.

The presence of a cross-connection represents a location in a distribution system through which backflow of contaminants or pollutants can occur. Backflow occurs when a non-potable source is at a greater pressure than the potable water distribution system. Backflow can occur from either backsiphonage or backpressure. Backsiphonage occurs when a non-potable source enters the drinking water supply due to negative (i.e., sub-atmospheric) distribution system pressure. Backpressure occurs when the pressure from a non-potable source exceeds the pressure in the potable water distribution system.

Backsiphonage may be caused by a variety of circumstances, such as main breaks, flushing, pump failure, or emergency firefighting water demand. Backpressure may occur when heating, cooling, waste disposal, or industrial manufacturing systems are connected to potable supplies and the pressure in the external system exceeds the pressure in the distribution system. Both situations act to change the direction of water, which normally flows from the distribution system to the customer, so that non-potable substances from industrial, commercial, or residential premises flows back into the distribution system through a cross-connection.

Cross-connections are not limited to industrial or commercial facilities. Submerged inlets are found on many common plumbing fixtures and are sometimes necessary features of the fixtures if they are to function properly. Examples of this type of design are siphon-jet urinals or water closets, flushing rim slop sinks, and dental cuspidors.

Older bathtubs and lavatories may have supply inlets below the flood level rims, but modern sanitary design has minimized or eliminated this cross-connection in new fixtures. Chemical and industrial process vats sometimes have submerged inlets where the water pressure is used as an aid in diffusion, dispersion, and agitation of the vat contents. Even though a supply pipe may be installed above a vat, backsiphonage can still occur. Siphon action has been shown to raise a liquid in a pipe such as water almost 34 feet. Some submerged inlets are difficult to control, including those which are not apparent until a significant change in water level occurs or where a supply may be conveniently extended below the liquid surface by means of a hose or auxiliary piping. A submerged inlet may be created in numerous ways, and its detection may be difficult.

City of Fountain Valley Cross Connection Control Management Plan (CCCMP) City of Fountain Valley CCCMP – June 2025
Chemical and biological contaminants have caused illness and deaths during known incidents of backflow, with contamination affecting several service connections, and the number of incidents reported is believed to be a small percentage of the total number of backflow incidents that actually occur. The public health risk from cross-connections and backflow is a function of a variety of factors including cross-connection and backflow occurrence and type and amount of contaminants.

A.2 Purpose of a Cross-Connection Control Program
The purpose of a cross-connection control program is to prevent the occurrence of backflow into a PWS’s distribution system in order to protect customers from contamination or pollution from any on-site hazards. Properly installed and maintained BPAs, devices or methods provide protection against the threat posed by many conditions typically found on a user’s premise.

The use of approved BPAs ensures that the appropriate performance evaluation of the assembly was conducted. It is important and required by the State CCCPH to select and properly install an approved BPA that is capable of protecting the distribution system from the hazard identified.

The success of a program depends on individuals that are knowledgeable about crossconnection control to identify actual and potential hazards, apply principles of backflow protection and prevention, and implement cross-connection control policies and procedures. A successful program will have ongoing surveillance of a PWS to ensure BPAs, devices or methods are working and identify new hazards or changes in the distribution system. Certified specialists are needed to properly evaluate the degree of hazard that exists in the distribution system. Hazards typically identified in distribution systems along with the required level of protection are specified in Chapter 3 of the State CCCPH.

A.3 Notes on Applicability of the Cross-Connection Control Policy Handbook The State CCCPH provides the basis for regulating the use and management of crossconnection control programs and BPAs in PWSs, and related requirements for supporting programs and policies. Activities or uses outside of the scope of the authority of the State Water Board to regulate PWSs are not regulated by the State CCCPH, including California Plumbing Code requirements and definitions not related to PWSs.

Recycled water cross-connection control installations and programs for the purposes of protecting the recycled water supply are not regulated by the State CCCPH, although a PWS that uses recycled water is regulated by the State CCCPH to ensure that a PWS’s drinking water system has adequate backflow protection from a recycled water system.

Water systems that do not meet the definition of a PWS (e.g., “State Small Water Systems” under CCR Title 22, Article 3) are not regulated by the CCCPH, although they may need to comply with the California Plumbing Code, local health agencies, and other laws or entities. __________________________________________

Assembly Bill No. 1671
CHAPTER 533
An act to amend Section 116810 of, and to add Sections 116407 and 116555.5 to, the Health and Safety Code, relating to drinking water. [Approved by Governor October 6, 2017. Filed with Secretary of State October 6, 2017.]
legislative counsel’s digest
AB 1671, Caballero. Backflow protection and cross-connection controls:
standards.
(1) Existing law, the California Safe Drinking Water Act, requires the State Water Resources Control Board to administer provisions relating to the regulation of drinking water to protect public health, including, but not limited to, conducting research, studies, and demonstration projects relating to the provision of a dependable, safe supply of drinking water, enforcing the federal Safe Drinking Water Act, adopting regulations, and conducting studies and investigations to assess the quality of private domestic water wells. Existing law makes certain violations of the act a misdemeanor.

Existing law requires any person who owns a public water system to ensure that the system does certain things, including, but not limited to, that it will not be subject to backflow under normal operating conditions. Existing law, to ensure that testing and maintenance of backflow prevention devices are performed by persons qualified to do testing and maintenance, authorizes local health officers to maintain programs for certification of backflow prevention device testers and requires the certification program to be consistent with backflow protection regulations adopted by the state board. A violation of these provisions, or an order by a local health officer pursuant to these provisions, is a misdemeanor.

This bill would require a public water system to implement a crossconnection control program that complies with, and would require the certification program to be consistent with, applicable regulations and the standards described in (2).
(2) Existing regulations establish standards for a backflow prevention device and cross-connection control.

This bill, on or before January 1, 2020, would require the state board to adopt standards for backflow protection and cross-connection control and would authorize the state board to do so through the adoption of a policy handbook, as specified. By authorizing the state board to adopt standards, the violation of which would be a crime, the bill would create a new crime and impose a state-mandated local program.

Chapter 14.17. CROSS-CONNECTION CONTROL

PROGRAM
§ 14.17.010. Purpose.

In cooperation with the State Water Resources Control Board Division of Drinking Water, City’s major goal is to ensure the distribution of a safe and potable water supply to all domestic water users. In order for the City to achieve this goal, a Cross-Connection Control Management Plan (CCCMP) is being developed with an effective date of July 1, 2025. The City’s CCCMP was developed pursuant to the requirements set forth in the Cross-Connection Control Policy Handbook (CCCPH) In accordance with standards established in the California Administrative Code CCCPH, as administered by the water superintendent, approved backflow prevention devices shall be installed to protect the public water supply system from contamination due to potential and actual cross-connections. Prevention of cross-connections include: (1) isolating, within the premises, contamination that may occur because of some undiscovered or unauthorized cross-connection on the premises; (2) eliminating existing connections between drinking water systems and other sources of water that are not approved as safe and potable for human consumption; (3) eliminating cross-connections between drinking water systems and sources of contamination; (4) safeguarding against cross-connections in the future. This shall be accomplished by the establishment of a cross-connection control program as required by state regulations. The ordinance codified in this chapter is adopted pursuant to CCCPH which replaced State of California Administrative Code Title 17, Sections §7583 through §7605 and applies to all State of California Public Water Systems, as defined in California’s Health and Safety Code (CHSC, section 116275(h))the State of California Administrative Code, Title 17, of the California Code of Regulations, "Regulations Relating to Cross- Connections," hereinafter referred to as the "state regulations." (Ord. 1247 § 2, 1996)
§ 14.17.020. Application.

This chapter shall be interpreted so as to comply with the state regulations on cross-connections as the same exist now, or as subsequently amended. The definitions set forth therein are adopted, except as otherwise provided.
(Ord. 1247 § 2, 1996)
§ 14.17.030. Administration.

The cross-connection control program shall be administered by the water department's cross-connection control specialist under the general supervision of the water superintendent. The water department will establish and maintain a list of approved backflow prevention assemblies, as well as a list of approved backflow prevention assembly testers. The cross-connection control specialist shall conduct necessary surveys of water user premises to evaluate the degree of potential health hazards. The water department shall notify the user when an assembly needs to be tested. The user shall receive a notice containing a due date for backflow prevention assembly testing.
(Ord. 1247 § 2, 1996)
§ 14.17.040. Cross-connection protection requirements.

The type of protection that shall be provided to prevent backflow into the public water supply system shall be commensurate with the degree of hazard, actual or potential, that exists on the water user's premises. Unprotected cross-connections with the public water supply are prohibited. The type of backflow protection assembly that may be required includes: air-gap separation (AG), reduced pressure Page 245 principle backflow protection assembly (RP), and double check valve assembly (DC) The types of backflow protection required to protect the approved water supply, at the user's water connection, to premises with varying degrees of hazard are listed in Table 1 of the state regulations. Situations which are not covered in Table 1 shall be evaluated on a case-by-case basis and the appropriate backflow protection shall be determined by the water superintendent in accordance with the nature of the hazard presented.
(Ord. 1247 § 2, 1996)
§ 14.17.050. Backflow prevention assemblies.
(a) Only backflow prevention assemblies which have been approved by the water department, in accordance with the state regulations, shall be acceptable for installation by a water user. A list of approved backflow prevention assemblies will be provided upon request. Backflow prevention assemblies shall be installed in a manner prescribed in the state regulations. Location of the assemblies shall be as close as practical to the user's connection. The water superintendent shall have the final authority in determining the required location of a backflow prevention assembly. Upon installation, backflow prevention assemblies shall be tested by an Orange County health department AWWA certified backflow tester.
(b) Testing of backflow assemblies shall be conducted only by an Orange County health department AWWA certified backflow tester that possesses a current city of Fountain Valley business license.

Backflow prevention assemblies must be tested immediately after installation, relocation or repair.

Approval must be obtained from the water department prior to removing, relocating or replacing a backflow prevention assembly.
(c) As a minimum, backflow prevention assemblies other than single-family residential irrigation systems, as well as other applications using atmospheric vacuum breakers, must be tested annually. More frequent testing may be required if deemed necessary by the water superintendent, based on facts demonstrating a potential hazard. No assembly shall be placed back in service unless it is functioning as required. These assemblies shall be serviced, overhauled or replaced, whenever they are found to be defective. All costs of testing, repair and maintenance shall be borne by the water user. (Ord. 1247 § 2, 1996)
§ 14.17.060. Inspection fee.

When a new backflow prevention assembly is installed or an existing backflow prevention assembly relocated, an installation inspection shall be completed by the water department. The installation inspection shall be conducted by the water department's cross-connection control specialist at the expense of the water user. The inspection fee, established by separate resolution, shall be paid by the water user prior to acquisition of water service. On single-family residential irrigation systems, as well as other applications where atmospheric vacuum breakers are considered appropriate backflow protection, no tests, inspections or fees shall apply.
(Ord. 1247 § 2, 1996)
§ 14.17.070. Water service termination.

When the water department encounters water uses that represent a hazard to the potable water supply that cannot be immediately abated by other means, the procedure for terminating water service shall be instituted. Conditions or water uses that create a basis for termination of water service shall include, but are not limited to the following:

(1) Refusal to install or to test a backflow prevention assembly, or to repair or replace a faulty backflow prevention assembly;
(2) Direct or indirect connection between the public water system and a sewer connection; (3) Unprotected, direct or indirect, connection between the public water system and a system or equipment containing contaminants;
(4) Unprotected, direct or indirect, connection between the public water system and an auxiliary water system.

Unless immediate action is required because of an urgent health and safety problem, the water department will terminate service to a water user's premises after proper notification has been sent. If no action has been taken within the allowed period, water service may be terminated, locked service valves installed, and service shall not be restored until corrections have been made, all provisions of this code met, and the public health, safety and welfare ensured. In cases in which immediate termination is required because of an urgent health and safety problem, service may be immediately terminated. The conditions constituting the urgent health and safety problem should be promptly documented. (Ord. 1247 § 2, 1996)
§ 14.17.080. Violations.

It is unlawful for any person, firm or corporation, at any time, to make or maintain, or cause to be made or maintained, temporarily or permanently, for any period of time whatsoever, any cross-connection between plumbing pipes or water fixtures being served with water by the city water department, and any other source of water supply, or to maintain any sanitary fixture or other appurtenances or fixtures which, by reason of their construction, may cause or allow backflow of water, or other substances, into the water supply system of the city, and/or the service of water pipes or fixtures of any consumer of the city, or to fail to comply with the provisions of this chapter. Violations shall be punished as provided in Chapter 1.16 of this code.

14.17.050 BACKFLOW PREVENTION ASSEMBLIES (a) Only backflow pre vention assemblies which have been approved by the Water Department, in accordance with the State Regulations, shall be acceptable for installation by a water user. A list of approved backflow prevention assemblies will be provided upon request. Backflow prevention assemblies shall be installed in a manner prescribed in the State Regulations. Location of the assemblies shall be as close as practical to the user's connection. The Water Superintendent shall have the final authority in determining the required location of a backflow prevention assembly. Upon installation, backflow prevention assemblies shall be tested by an Orange County Health DepartmentAWWA certified backflow tester. (b) Testing of backflow assemblies shall be conducted only by an Orange County Health Department AWWA certified backflow tester that possesses a current City of Fountain Valley business license. Backflow prevention assemblies must be tested immediately after installation, relocation or repair. Approval must be obtained from the Water Department prior to removing, relocating, or replacing a backflow prevention assemply. 4 1247

(c) As a minimum, backflow prevention assemblies other than single-family residential irrigation systems, as well as other applications using atmospheric vacuum breakers, must be tested annually. More frequent testing may be required if deemed necessary by the Water Superintendent, based on facts demonstrating a potential hazard. No assembly shall be placed back in service unless it is functioning as required. These assemblies shall be serviced, overhauled or replaced, whenever they are found to be defective. All costs of testing, repair and maintenance shall be borne by the water user.

14.17.060 INSPECTION FEE When a new backflow prevention assembly is installed or an existing backflow prevention assembly relocated, an installation inspection shall be completed by the Water Department. The installation inspection shall be conducted by the Water Department's Cross-Connection Control Specialist at the expense of the water user. The inspection fee, established by separate resolution, shall be paid by the water user prior to acquisition of water service. On single-family residential irrigation systems, as well as other applications where atmospheric vacuum breakers are considered appropriate backflow protection, no tests, inspections, or fees shall apply. 5 1247

14.17.070 WATER SERVICE TERMINATION When the Water Department encounters water uses that represent a hazard to the potable water supply that cannot be immediately abated by other means, the procedure for terminating water service shall be instituted. Conditions or water uses that create a basis for termination of water service shall include, but are not limited to the following:

1. Refusal to install or to test a backflow prevention assembly, or to repair or replace a faulty backflow prevention assembly.

2. Direct or indirect connection between the public water system and a sewer connection. 3. Unprotected, direct or indirect, connection between the public water system and a system or equipment containing contaminants.

4. Unprotected, direct or indirect, connection between the public water system and an auxiliary water system.

Unless immediate action is required because of an urgent health and safety problem, the Water Department will terminate service to a water user's premises after proper notification has been sent. If no action has been taken within the allowed period, water service may be terminated, locked service valves installed, and service shall not be restored until corrections have been made, all provisions of this code met, and the public health, safety and welfare ensured. In cases in which immediate termination is required because of an urgent health and safety problem, service may be immediately terminated. The conditions constituting the urgent health and safety problem should be promptly documented. 6 124/

14.17.080 VIOLATIONS It is unlawful for any person, firm, or corporation, at any time, to make or maintain, or cause to be made or maintained, temporarily or permanently, for any period of time whatsoever, any cross-connection between plumbing pipes or water fixtures being served with water by the City Water Department, and any other source of water supply, or to maintain any sanitary fixture or other appurtenances or fixtures which, by reason of their construction, may cause or allow backflow of water, or other substances, into the water supply system of the City, and/or the service of water pipes or fixtures of any consumer of the City, or to fail to comply with the provisions of this chapter. Violations shall be punished as provided in Chapter 1.16 of this Code."
