Pipe Blockage Control Program
The goal of the Pipe Blockage Control Program is to reduce the amount of Pipe Blocking Materials such as Fats, Oils and Grease Wipes, Roots, etc… discharged to the sanitary sewer system. The City has determined that these items do not pose a problem within the Industrial Sewer Collection and Conveyance System and therefore is not required to meet additional regulatory requirements identified for this Element.
System Evaluation, Capacity Assurance, and Capital Improvement Plan The City has conducted several studies of the Industrial System between 2001, 2008, and 2022 to assess the existing, near term and long-term capacity needs to safely convey wastewater to the Industrial Wastewater Treatment Plant. These analyses indicate that there is adequate capacity under existing conditions for the collection and conveyance system. In the near term. When discharges reach 2 mgd some improvements may be required , however additional analyses will be required to confirm capacity needs. Capacity needs for the long term will depend on the number and size of facilities connected in the future. The City has identified one area for capacity upgrades within the Industrial System. The Airport Boulevard Lift Station is planned to be upgraded in 2026 to address capacity deficiencies to meet existing and future flow additions upstream. An additional Vulnerability Assessment will be required to meet some of the additional (2022) requirements included in the WDRs.
Monitoring, Measurement, and Program Modifications
The City monitors the implementation of the SSMP Elements in order to measure the effectiveness of the City SSMP program in reducing sewer spills. This SSMP Element outlines the manner in which each SSMP Element is monitored and evaluated and the schedule with which the City completes this monitoring and evaluation.
Sewer System Management Plan Program Audits
The SSMP Program Audits Element outlines the audit process and identifies City Staff responsible for conducting or participating in SSMP Program Audits and generating the required SSMP Program Audit Report. SSMP Program Audits must occur at a minimum of every three (3) years and are required to evaluate the City SSMP Program, identify program deficiencies, and provide an improvement schedule based on the audit findings.

1.4 System Asset Overview and Service Area
The City of Salinas is incorporated as a charter City on March 4, 1874, and operates under the Council-Manager form of government. The City is governed by a six-member Council elected by districts for four-year alternating terms and a Mayor elected at large for a two-year term. The Council appoints the City Attorney and the City Manager who is responsible for day-to-day administration of the City under the policy direction of the Council.
The City of Salinas operates a unique Industrial Wastewater Sewer Collection, Conveyance & Treatment System. While most municipalities maintain a Storm Sewer and a Sanitary Sewer System only, Salinas maintains a third collection system for a service area on the southern end of the City. The Industrial Wastewater Sewer receives industrial wastewater discharges from 23 industrial users via permitted connections; and conveys the discharge to a 200-acre treatment facility located along the Salinas River. The treatment facility and collection system are solely funded by user fees from the current roster of 23 industrial users. The industrial waste fund is adequate for the immediate operations and maintenance of the treatment facility and collection system.
The City industrial wastewater collection system consists of approximately 0.5 miles of force Sewer System Management Plan (IW) – Revision 02

The IW sewer system allows fifteen (15) facilities of the twenty-three (23) that operate year-round to divert stormwater into the sewer system from outdoor areas of industrial activity. The City has two existing stormwater diversion structures (Phase 1A, constructed in 2020) within the IW sewer system. The City plans to make additional improvements (Phase 2A) in the future to facilitate additional stormwater diversion from the southeast section of Salinas into the industrial sewer system. A schematic of Phase 1A and Phase 2A stormwater projects is shown below:
The improvements to integrate additional (Phase 2A) stormwater into the industrial sewer system is a long-term goal. The date to move forward with this project was not determined at the time this 2025 revision of the SSMP was developed.
Data management for the operations and maintenance of the sewer systems is provided utilizing the City Computerized Maintenance Program utilizing ArcGIS field mapping applications. The web-based application includes map updates, data storage and produces t asks for sewer inspections and maintenance.
Sewer laterals are owned, operated and maintained by individual property owners from the wye connection at the sewer main, back to each building. The City does not own or maintain any sewer laterals within the service area.

Sewer System Management Plan – Revision 02
Element 7 – Fats, Oils and Grease Control Program
City of Salinas
May 2025
ELEMENT 7 – PIPE BLOCKAGE CONTROL PROGRAM
The City of Salinas does not have a significant number of Commercial/Industrial Facilities that contribute Fats, Oils and Grease (FOG) or other Pipe Blocking Materials into the industrial sewer system. Pipe Blocking Materials have not been a contributing factor in any industrial system sewer spills.
7.1 Regulatory Requirements
WDR Order No. 2022-0103-DWQ Attachment D 7 states:
The Sewer System Management Plan must include procedures for the evaluation of the Enrollee’s service area to determine whether a sewer pipe blockage control program is needed to control fats, oils, grease, rags and debris. If the Enrollee determines that a program is not needed, the Enrollee shall provide justification in its Plan for why a program is not needed. The procedures must include, at minimum:
(a). An implementation plan and schedule for a public education outreach program that promotes proper disposal of pipe blocking substances; (b). A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area;
(c). The legal authority to prohibit discharges to the system and identify measures to prevent spills and blockages;
(d). Requirements to install grease removal devices (such as traps or interceptors) and the development of design standards for such devices, maintenance requirements, BMP requirements, record keeping and reporting requirements; (e). Authority to inspect grease producing facilities, enforcement authorities, and whether the City has sufficient staff to inspect and enforce the FOG ordinance; (f). An identification of sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section; and Implementation of source control measures for all sources of fats, oils, and grease reaching the sanitary sewer system for each section identified above
7.2 Pipe Blockage Control Program Public Outreach
The focus of an effective Pipe Blockage Control Program for the industrial system will include commercial and industrial facilities.
The City provides the following outreach and education materials that consist of the following:
• Residential and commercial outreach on proper Disposal of Wipes - “Toilets are not Trashcans” flyer which can be found on the City website:
https://www.cityofsalinas.org/Your-Government/Find-a-Department/Public- Works/PW-Maintenance-Services/Environmental-Maintenance-Services/Sanitary- Sewer-Maintenance
Sewer System Management Plan – Revision 02
Element 7 – Fats, Oils and Grease Control Program
City of Salinas
May 2025
• These facilities are also regulated by the City’s wastewater pretreatment program which includes regular inspections and outreach on discharge prohibitions to the City’s industrial sewer system.
7.3 City Determination that a FOG Program is not Required The Cities industrial waste collection system has neither historically nor currently had Fats, oils or grease issues within its collection system. Most of the Industrial Waste Facility (IWF) users are fresh vegetable processors, packers, and coolers. Included in this group are the fresh-pack salad producers that continue to be the fastest growing segment of the City's users. Chlorinated effluent, ammonia refrigerant, solids, and hydraulic oil spills typify the potential concerns with their wastewater discharge. Two box companies comprise the next group of users. These companies manufacture corrugated cardboard containers using prefabricated rolled paper and use ink and waxes in the process of labeling and finishing the boxes. Control of heavy metals, hydraulic oil spills, wax and starch spills, high TDS, varying pH and slug discharges are potential concerns from this group.
Cal Marine Fish Company is the sole processor of seafood at one facility. Squid, herring, crab and shrimp are among the products prepared at this facility. From this seafood group, the City specifically monitors BOD, screening and sanitation. Although oils from fish processing present a potential concern, the oils, if any, do not present an issue for buildup in the collection system.
Due to the small percentage of flow from this facility this user does not present a fats oils or grease source control problem for the collection system. There are no fats or grease discharged from the facility.
A FOG program is not indicated with the current industrial waste dischargers group.
7.4 Discharge Prohibition Legal Authority and Spill Prevention Measures The City’s current source control program is run in cooperation with the Monterey One Water Source Control Program and relies heavily on Monterey One Water ordinances and requirements.
The City’s current Municipal Code expressly incorporates all Monterey O ne Water regulations, including those related to requirements for source control and pretreatment requirements.
Monterey One Water’s authority for the Source Control Program is derived from Ordinance 2008-
1. The City of Salinas City Code Chapter 36 expressly requires that all users within the City comply with all Monterey One Water regulations.
• Sec. 36-12.2. Compliance with discharge requirements of Monterey One Water. All dischargers into the sanitary sewer shall comply with all the discharge requirements of Monterey One Water. (Ord. No. 2102 (NCS).)
• Section 36-1 acknowledges that the City’s sanitary sewer collection system is tributary to the Monterey One Water treatment facility. It states that Monterey One Water implements a pretreatment program for its member jurisdictions (including the City of Salinas).

• Section 36-11 requires that all private sewage disposal system conform with the city plumbing code currently in effect.
• Section 36-12 requires that a City permit be issued for all connection to or use of the public sanitary sewer system.
• Sections 36-12.1 and 36-12.2 state that final approval for a sanitary sewer permit is contingent upon compliance with the requirements of Monterey One Water and that all dischargers into the sanitary sewer must comply with all discharge requirements of Monterey One Water.
• Section 36-16 requires that design and construction of building sewers conform to the requirements of the city plumbing code and the City Design Standards and Standard Specifications currently in effect at the time of installation. (Elsewhere in the City Code, the California Plumbing Code is adopted by reference.)
7.5 High Maintenance Problem Area Identification and Sewer Cleaning The City has not experienced any sewer spills that resulted from pipeline obstructions or plugs due to any pipe blocking materials. Between 2010 and 2024, CIWQS records show the causes of three (3) sewer spills as follows:
• Pressure Relief Valve Failure (Force Main)
• Pump Station Controls
• Pump Station Controls
There are currently no high maintenance problem areas that require more frequent cleaning.
City staff will continue to monitor the system in the event high frequency cleaning areas of the system are identified.

8.2 System Evaluation
Overview and Background
The City of Salinas IWTF is located south of the City adjacent to the Salinas River. It treats industrial wastewater discharges from industrial customers located in the southeastern part of the City. The industrial wastewater is conveyed from customer sites to the industrial treatment facility by the City’s industrial sewer system. This chapter addresses the industrial sewer system.
The industrial sewer system is completely separate from the sanitary (domestic) sewer system. All sanitary (domestic) wastewater is collected in a separate sanitary sewer system and conveyed to the Monterey One Regional Treatment Plant (M1W RTP) located north of Marina CA. A separate Sanitary Sewer Management Plan addresses the sanitary sewer system.
The City has conducted several studies over the past years to evaluate capacity needs in the industrial sewer system. These studies include:
o “Relocation Feasibility Study for Industrial Wastewater Treatment Facility”, prepared for City of Salinas by CDM, December 2001.
o “Industrial Wastewater Main Line Capacity Analysis”, prepared for City of Salinas by C&D (Creegan & D’Angelo) Consulting Engineers, November 2003. o “Recommended Capital Improvement Program for Industrial Wastewater Treatment Facility”, prepared for City of Salinas by CDM, June 2004. o “Industrial Wastewater System – Conceptual Approach for System Expansion”, Summary Report prepared for City of Salinas by CDM, July 2008. o “Industrial Waste Conveyance System Study”, prepared for the City of Salinas by Wood Rodgers, December 2008.
o “Industrial Wastewater Capacity Analysis, prepared by Carollo Engineers, November 2022.
Existing Industrial Sewer System
The major industrial sewer conveyance system consists of approximately 38,600 feet of 12, 15, 18, 27, 33, 36 and 42 -inch reinforced concrete and HDPE pipe. The pipeline system conveys industrial flows from the customer locations to the industrial wastewater plant.
The 27-inch pipe originates where Sanborn Road crosses over the railroad tracks, passes through a 60-foot-long inverted siphon at the Abbott Street and East Blanco Road intersection, and then continues downstream for about 1600 feet where it intersects the east 27-inch trunk line. From there, it continues for an additional 2600 feet before it enters the 36-inch pipeline near the intersection of East Blanco Road and La Mesa Way.
The 36-inch pipeline then drains to and through the former Salinas wastewater treatment plant site (TP1 site). At that point, it discharges into a new 42 -inch HDPE pipeline that flows southerly to the IWTF.
Sewer System Management Plan (IW) – Revision 02
Element 8 – System Evaluation and Capacity Assurance Plan
City of Salinas IW
May 2025
Industrial Wastewater Flow Projections & Capacity Evaluation The industrial customers are primarily food processing and related businesses. Many customers conduct fresh vegetable packing operations. Some customers provide related services such as manufactured ice, refrigerated warehousing, and corrugated and solid fiber boxes.
The industrial wastewater facility operates year-round. However, different from a sanitary sewer system, the industrial sewer flows are lower in the winter because some customers, particularly fresh vegetable packing and cooling facilities, move their operations to warmer southern locations. Approximately ½ of the industries remain open year- round.
The industrial system must be able to accommodate the flows during the high use periods, which occur during the summer peak growing/harvesting season. The treatment facility must be able to treat the average monthly flow during the high use periods and have peaking ability to accommodate the high day flows. The conveyance system from customers to the treatment facility must accommodate the high day (peak) flow.
A collection system model was developed to evaluate system capacity in the industrial waste system. The model assessed the conveyance capacity for the collection system and the impacts of future developments and land use changes.
InfoSWMM+, developed by Innovyze was selected as the new software platform for the City's updated hydraulic model. The hydraulic modeling engine for InfoSWMM+ uses the Environmental Protection Agency's (EPA's) Storm Water Management Model (SWMM), which is widely used throughout the world for planning, analysis, and design related to stormwater runoff, combined sewers, sanitary sewers, and other drainage systems.
InfoSWMM+ routes flows through the model using the Dynamic Wave method, which solves the complete Saint Venant, one dimensional equations of fluid flow. The equation is based on mass conservation and momentum conservation principals.
The hydraulic model was developed from drawings, and previous reports on the IWWCS.
The Influent Pump Station (IPS) and Airport Lift Station are included in the model with associated pump curves. Due to unknown conditions of existing pipelines, a conservative Manning's “n” factor of 0.013 was used for the evaluation of all existing collection system gravity pipelines and a Hazen Williams factor of 120 was used for the force mains.
The analysis involved identifying total capacity within the collection system and evaluating areas where pipe capacity is inadequate to convey peak flows (Monitored and Allotted) and could cause the pipeline to surcharge. For this analysis pipelines were assumed capacity deficient if they were modeled to surcharge under peak flow conditions.
Collection systems that lack sufficient capacity create bottlenecks in the sewer and potentially contribute to sanitary sewer spills. The City's industrial waste system was evaluated with the hydraulic computer model, which provided a platform for effectively identifying and managing capacity deficiencies within the industrial waste system.
Sewer System Management Plan (IW) – Revision 02
Element 8 – System Evaluation and Capacity Assurance Plan
City of Salinas IW
May 2025
Industry standard practice is to require that sewage lift stations have sufficient capacity to pump peak flows with the largest pump out of service (firm capacity). Force main piping should be sized to provide a minimum velocity of 3 feet per second (fps) at the design flow rate of the lift station and no more than 6.5 fps. For the determination of head loss, the Hazen-Williams equation is used with a C-factor of 120, which is typical for collection system master planning purposes.
The 2022 Carollo Report concluded the following:
o Under existing conditions, the IWWCS gravity mains have capacity to convey industrial flow to the IWTF. Figure 2.2 shows the flow-depth-to-pipe-diameter (d/D) ratio. As shown, the d/D illustrates that the system has additional capacity under existing peak flow. The 27-inch diameter pipeline on Blanco Road, south of Abbot Street has a d/D of 0.51 and the 33-inch diameter pipeline upstream of TP-1 has a d/D of 0.56. o The system has capacity to convey peak flow. A segment of 33-inch diameter pipeline upstream of TP-1 has a small gradient and reduces capacity within the system. Capacity within the system was considered to be deficient when the d/D exceeded 0.9 within the gravity system in the future.
o The Airport Lift Station is capacity deficient under existing peak flow. The existing capacity of this lift station is 1.04 mgd, however the existing system’s peak flow potential is 3.89 mgd. The analysis recommends increasing the firm capacity to 4 mgd and total capacity to 6 mgd. The associated 14-inch diameter force main does not exceed the velocity criteria and is not considered to be capacity deficient. o Under future peak flow conditions replacing approximately 900 feet (ft) of 33-inch diameter pipeline with 42-inch diameter pipeline. The project is located east of TP-1 within an open field. This segment of pipeline has a small inclination relative to upstream pipelines and is shown below:

8.3 Design Criteria
Chapter 36 “Industrial Waste, Wastewater Collection and Discharge” of the City’s Municipal Code specifies the requirements for discharge to the City’s industrial wastewater system.
These requirements are applicable to existing and new customers of the industrial wastewater system.
Unlike the municipal sanitary sewer system, the peak flows for the industrial wastewater system occur during the summer peak growing season months. Winter rainfall (RDII) is not an issue for capacity of the IWWCS, as industrial wastewater flows are very low in the winter months. During the period with high industrial wastewater discharges, there is no or negligible rainfall.
The hydraulic criteria evaluated the pipes adequacy to handle the projected flows without surcharge, i.e., flowing full but no surcharge based on Manning’s equation. Those pipes without adequate capacity to meet the criteria have been identified for improvement.
The City’s Standard Specifications (current version) specify the requirements for sewer pipe materials, installation methods, and testing for new sewer improvements.
8.4 Schedule and Funding for Capacity Improvements
Immediate Needs to 2025
The City’s industrial wastewater system will require some improvements in order to meet estimated needs. The Industrial Lift Station located at the south end of Airport Boulevard near Hansen Street will require increased capacity to accommodate any additional flows upstream. However, the major industrial pipeline system has adequate capacity for estimated peak flows. Some system redundancy is provided by the Industrial Wastewater Diversion Project which consists of a bypass to the M1W sanitary sewer system installed at the TP1 site. M1W’s Salinas Area Pump Station (SAPS) is located at the TP1 site which conveys sanitary wastewater from the City to the RTP operated by M1W. The Industrial Wastewater Diversion Project was completed in 2016. This project also included construction of an emergency wastewater bypass system to allow mixed wastewaters to flow to the IWTF instead of to the Salinas River in the event of a catastrophic failure at the M1W Salinas Pump Station.
The design phase of the Airport lift station upgrade has been completed. The City plans to bid the project in 2025 with project completion anticipated in 2026.
Ultimate Needs
The improvements identified above for near-term implementation are sized to accommodate the anticipated buildout total instantaneous peak flows reaching the TP1 site and treatment facility.
Ultimately, the need for additional pipeline improvements would depend on future additions of industrial customers, and the City’s decisions in the near term on the appropriate location for
Sewer System Management Plan (IW) – Revision 02

additional treatment capacity. This plan will be updated as needed consistent with future updates to any conceptual expansion plans.
The table below summarizes the timeframe and estimated capital costs for the conceptual improvements to provide additional capacity in the industrial wastewater system. These order of magnitude costs by timeframe are at a conceptual planning level and are based on previous studies. The costs will be updated and refined as part of subsequent detailed studies to refine and select specific improvement projects.
Industrial Waste System Capital Projects
Item Estimated Capital
Cost ($ Million, in
2018 dollars)
Immediate Measures (by 2026)
New Industrial Lift Station at Airport Boulevard $2.26
The City currently funds the industrial wastewater system through a monthly user rate consisting of: a monthly service charge, total flow charge, and an average BOD charge. The rates cover operations and maintenance expenses, capital improvements and past debt service on any outstanding bonds that have been issued for capital improvements.
Capital improvements to provide capacity for future customers also benefit existing customers by improving the overall function of the IWWCS. the existing treatment facility.
Potential funding methods to cover the costs of these capital improvements are identified below. The potential funding methods must be further evaluated to determine their applicability. While all the options are feasible, some may be more applicable or more desirable for the specific conditions. It is anticipated that a combination of options will be utilized.
As recommended in the conceptual expansion plan (CDM, 2008), the City is planning to conduct a detailed financing study to determine the preferred approach and appropriate methods for funding the required improvements for both pipeline conveyance and for treatment facility expansion. It is anticipated a combination of multiple funding sources will be used. Most of the methods are available only to municipalities or other government agencies; however, there are some that could be utilized by the individual industries.
Grant programs from the EDA Public Works and Economic Development Program, the State Water Resources Control Board and others are preferred funding sources for IWWCS upgrades. If grant funding proves to be unavailable other potential funding options may also include:
o User rates
o Connection fees
Sewer System Management Plan (IW) – Revision 02
Element 8 – System Evaluation and Capacity Assurance Plan
City of Salinas IW

o Municipal bonds
o Special assessment districts
o Public/private partnerships
o California Infrastructure and Economic Development Bank: infrastructure state revolving fund program; industrial development bonds
o California State loans and grants: State Revolving Fund (SRF); direct state appropriations
o Federal grants and loans: EDA Public Works and Economic Development Program; direct federal appropriations
The schedule for implementation of future capacity improvements will depend on the available funding and the schedule for future additions and expansion of the IWWCS. As part of its annual budgeting and CIP process, City staff will refine the implementation schedule for specific projects.
8.5 Additional WDR Requirements
The City plans to conduct a Vulnerability Assessment to address the following WDR requirements:
o Prioritize the condition assessment of system areas that:
▪ Hold a high level of environmental consequences if vulnerable to collapse, failure, blockage, capacity issues, or other system deficiencies; ▪ Are located in or within the vicinity of surface waters, steep terrain, high groundwater elevations, and environmentally sensitive areas; o Are within the vicinity of a receiving water with a bacterial-related impairment on the most current Clean Water Act section 303(d) List;
o Assess the system conditions using visual observations, video surveillance and/or other comparable system inspection methods;
o Utilize observations/evidence of system conditions that may contribute to exiting of sewage from the system which can reasonably be expected to discharge into a water of the State;
o Identify system assets vulnerable to direct and indirect impacts of climate change, including but not limited to: sea level rise; flooding and/or erosion due to increased storm volumes, frequency, and/or intensity; wildfires; and increased power disruptions. o Outline how capacity assessment considers:
▪ Data from existing system condition assessments, system inspections, system audits, spill history, and other available information; ▪ Capacity of flood-prone systems subject to increased infiltration and inflow, under normal local and regional storm conditions;
▪ Capacity of systems subject to increased infiltration and inflow due to larger and/or higher-intensity storm events as a result of climate change; ▪ Increases of erosive forces in canyons and streams near underground and above- ground system components due to larger and/or higher-intensity storm events;
o Capital Improvement Plan that includes:
