Water Shortage Contingency Plan Rivers ide Public Utilities 1 This document represents the Water Shortage Contingency Plan (WSCP) adopted by the City of Riverside Public Utilities Department (RPU). The document follows the structure recommended in guidance documents prepared by the California Department of Water Resources (DWR). The numbering of Sections 1 through 12 corresponds with the numbered sections in the UWMP Guidebook.

RPU's 2010 Urban Water Management Plan (UWMP) included a WSCP and three supporting appendices:
 RPU Water Rule #9 (Shortage of W ater Supply and Interruption of Delivery, also known as the Water Shortage Ordinance)
 RPU Water Rule #15 (Water Waste)
 A draft Water Conservation Ordi nance that expanded on the Water Shortage Ordinance and was recommended for approval by the City’s Board of Public Utilities after the preparation of the 2010 UWMP. The Water Conservation Ordinance amended the Riverside Municipal Code (RMC) Title 14 and included a detailed description of unreasonable uses of water, RPU's Water Conservation Program, responses to water shortage emergencies, and enforcement and severability.

In July of 2014, the City Council adopted revisions to the City’s Water Conservation Ordinance, as set forth in RMC Chapter 14.22, and adopted a resolution implementing Stages 1 and 2 of the City’s Water Conservation Ordinance. The City’s revisions to Chapter 14.22 changed Stage 2 restrictions from voluntary to mandatory. The City also limited non-agricultural landscape watering to four days in Stage 2 and decreased the non-agricultural landscape watering to three days in Stage 3.

In June of 2015, the City Council adopted additional changes to the Water Conservation Ordinance. The changes included additional restrictions on irrigation water use and an updated enforcement policy. The City also adopted a resolution implementing Stages 1, 2, and 3 of the Water Conservation Ordinance.

In 2018, new legislation expanded the required elements of a WSCP. RPU has prepared this updated WSCP to meet these requirements and is adopting it alongside its 2020 UWMP.

This plan addresses actions that RPU would take as a wholesale supplier and as a retail supplier.

The WSCP is a separate document from the UWMP. RPU will continue to monitor the effectiveness of this WSCP, and if the need arises to modify this plan, RPU will follow the update procedures described in Section 12.

This section summarizes the supply reliability analysis presented in the UWMP and highlights key issues that could create a shortage condition.

RPU’s supplies generally have a high degree of reliability. RPU’s primary source of supply is local groundwater. RPU has fixed extraction rights under the Western-San Bernardino Judgment, based upon a five-year rolling average. RPU generally under-produces below its fixed rights. Should a drought increase demand, RPU has the capacity and rights to increase pumping to maximize its fixed extraction rights in that drought year. RPU is able to meet current demands with local groundwater production. As an additional backup supply source, RPU has access to imported water through Western Municipal Water District (WMWD). RPU is also able to receive water through an interconnection with Norco during an emergency.

Chapter 7 of RPU’s UWMP presents a supply reliability analysis for a five-year dry period. This analysis shows that RPU could continue to meet demands without the use of imported water. Although that analysis demonstrates that RPU’s urban water supply is reliable, there are potential issues that could create a shortage condition. These include:
 An extended drought more severe than historic events, possibly impacted by climate change  An extended and wide-sp read power outage caused by a natural disaster or malevolent acts Water Shortage Contingency Plan Rivers ide Public Utilities 2  A regional emergency such as a hazardous chemical spill or a terrorist attack  Regulatory mandates to reduce water use
Water shortage contingency planning provides a way to plan for these risks and anticipate actions that should be implemented to manage the impacts. This plan describes how RPU intends to respond to such shortage events.

RPU will be required to prepare an Annual Water Supply and Demand Assessment, referred to by DWR as the Annual Assessment, and submit it to DWR each year, beginning July 1, 2022. The Annual Assessment is intended to meet requirements of Water Code Section 10632.1 and present an assessment of the likelihood of a water shortage occurring during the next 12 months. This section of the WSCP outlines the procedures that RPU will use to prepare the Annual Assessment. The procedures defined in this section will allow RPU to follow a consistent annual procedure for making the determination of whether to activate the WSCP.

Decision Making Process
RPU will use the following procedures in preparing the Annual Assessment.

1. In January and F ebruary of each year, RPU staff will review available data related to anticipated supplies and demands. RPU staff will coordinate with WMWD and the City of Norco on the regional outlook for water supply reliability.

2. In April of each year, RPU staff will present a recommendation to the RPU Board of Directors for approval. The board will approve the determination of supply reliability and will take actions to implement shortage response actions, if needed. The board will provide public notice of a hearing to consider changes in the implementation of shortage response actions.

3. In May of each year, RPU will prepare the Annual Assessment with required information and submit it to DWR.

The timeline may be modified to reflect updated information available from surrounding agencies. For example, the Metropolitan Water District of Southern California (MWD) will be preparing its own Annual Assessment each year. The draft WSCP published by MWD describes a process of preparing the Annual Assessment for approval by the MWD Board of Directors in June of each year. This information may help inform the Annual Assessment prepared by WMWD, and RPU may wish to coordinate its analysis with that of WMWD. RPU staff would seek to make RPU’s Annual Assessment reflective of the most current information available from its supply partners.

Data and Methodologies
This section describes the data and methodologies that will be used by RPU to evaluate water system reliability for the coming year, while considering that the year to follow could be dry.

2.2.1 Evaluation Criteria
RPU will rely on locally applicable criteria for each Annual Assessment. These criteria will include the Annual Report of the Western-San Bernardino Watermaster, which describes groundwater conditions in the San Bernardino Basin Area, the Riverside Basin, and the Colton Basin.

2.2.2 Water Supply
RPU’s anticipated supplies will be quantified for the near-term, and descriptive text will be used to note any anticipated reductions in supply.

2.2.3 Unconstrained Customer Demand
Water Shortage Contingency Plan Rivers ide Public Utilities 3 RPU will prepare an estimate of unconstrained demand (as the term is used in Water Code Section 10632(a)(2)(B)(i)). The estimated demand will be calculated using the demand projection approach described in the UWMP, in combination with updated data for connections, climate, changes in land use, and recent water usage history.

2.2.4 Planned Water Use for Current Year Considering Dry Subsequent Year RPU will describe the anticipated use of water supplies for the coming year, with the anticipation that the following year will be dry. The supplies will be characterized in a manner consistent with the UWMP, in combination with updated data for climate and recent observations.

2.2.5 Infrastructure Considerations
RPU will describe any potential infrastructure constraints on the ability to deliver adequate supplies to meet expected customer demands in the coming year. RPU will show that its system of wells, pipelines, pump stations, and storage tanks have adequate capacity to deliver the anticipated demands. RPU will describe any anticipated capital projects that are intended to address constraints in production, treatment, or distribution.

2.2.6 Other Factors
RPU will describe any specific locally applicable factors that could influence or disrupt supplies. RPU will also describe unique local considerations that are considered as part of the annual assessment.

Since the preparation of the 2015 UWMP, the Water Code has been amended to define six standard shortage levels. The six standard water shortage levels correspond to progressively increasing estimated shortage conditions (up to 10-, 20-, 30-, 40-, 50- percent, and greater than 50-percent shortage compared to the normal reliability condition). If an agency elects to retain an existing set of shortage levels from its previous WSCP, then the document must provide a crosswalk to relate the existing stages to the six standard stages.

RPU’s agreements with its wholesale customers (WMWD and Norco) call for deliveries to be suspended during periods when surplus water is not available. RPU’s plan addresses the stages and actions it will take as a retail supplier.

RPU’s updated plan has five shortage stages. The Water Conservation Stage shall be set by City Council action. All normal water efficiency programs and water conservation regulations shall remain in force during any stage, unless the City Council directs otherwise.

Wholesale Shortage Levels
RPU’s wholesale customers receive only surplus water by agreement. Therefore, wholesale deliveries will cease if RPU lacks surplus water and enters a water shortage Retail Shortage Levels
RPU’s updated WSCP includes five stages. Stage One represents normal conditions. Stage One conservation measures are voluntary, and will be encouraged and promoted through public outreach, education, and awareness measures by the City.

Stages Two, Three, Four, and Five represent potential and actual shortages. Stages Two, Three, Four, and Five may be triggered by a local or regional water supply shortage; production, treatment, transmission, or delivery infrastructure problems; limited or unavailable alternative water supplies; or other circumstances. Stages Two, Three, Four, and Five conservation measures are mandatory, and violations may be subject to criminal, civil, and/or administrative action. Stage One conservation measures become mandatory when Stage Two, Three, Four, or Five are declared.

Water Shortage Contingency Plan Riversi de Public Utilities 4 Stage Five Water Shortage Emergency may be an immediate emergency, or a threatened future water shortage, or both.

Upon declaration of a Water Shortage Emergency:
1) No new construction meters will be issued.
2) No construction water may be used for earth work such as road construction purposes, dust control, compaction, or trench jetting.
3) No new building permits shall be issued, except:
a) Projects found by the City C ouncil to be necessary for public health and safety. b) Projects using recycled water for construction.
c) Projects which will not resul t in a net increase in non-recycled water use. d) Projects with adequate Conservation Offsets, if available. The City, in its sole discretion, may choose to make Conservation Offsets available. Conservation Offset costs shall be based on the cost of conserving the water elsewhere to provide the water needed for a project, the cost of providing an alternative water supply deemed acceptable by the City, or other measures as may be found in the City’s Water Use Efficiency Master Plan. Conservation Offset fees will be set forth in the Water Rules and Rate Schedules.

During a mandated reduction, RPU will intensify its water conservation programs, especially public education. RPU promotes efficient water use including non-potable uses such as landscaping and irrigation (Chapter 19.67 of the Riverside Municipal Code).

As part of this update, RPU added a fifth stage for shortages of greater than 50 percent. RPU has elected to use these five stages and provide a crosswalk to relate RPU’s stages to the six standard stages. This crosswalk is shown in Table 1.

Stage One (Normal Water Supply) applies when the City can meet all of its water demands, but declares, by resolution, that it has determined that certain conservation methods are warranted to preserve existing water supplies in the event the City will be unable to meet future water demands with its local water supplies. Any other normal water efficiency programs and water conservation regulations remain in force during Stage One.
2 < 15%
Stage Two (Minimum Water Shortage) applies when the City Council declares, by resolution, a reasonable probability exists that the City will not be able to meet all of its water demands with its local water supplies, other regional or statewide conditions warrant implementation; or RPU faces an actual supply shortage of up to 15%, corresponding to CA Water Code section 10632 shortage levels 1 and 2.
3 15 – 20%
Stage Three (Moderate Water Shortage) applies when the City Council declares, by resolution, a reasonable probability exists that the City will not be able to meet all of its water demands with its local water supplies, other regional or statewide conditions warrant implementation; or RPU faces an actual supply shortage of 15-20%, corresponding to CA Water Code section 10632 shortage levels 2 and 3.
4 20 – 50%
Stage Four (Severe Water Shortage) applies when the City Council declares, by resolution, that the City's ability to meet its water demands with its local water supplies is seriously impaired; or RPU faces an actual supply shortage of 20-50%, corresponding to CA Water Code section 10632 shortage levels 3, 4, and 5.
5 >50%
Stage Five Water Shortage Emergency applies when the City Council declares, by resolution, that the City’s ability to meet its water demands with its local water supplies is so seriously impaired that RPU faces an actual supply shortage of over 50%,
corresponding to CA Water Code section 10632 shortage level 6.

The WSCP limits water demand during times of shortage in five stages. These stages can be triggered when there is water deficiency caused by limitations on supply or by limitations on RPU’s delivery system.

The plan shall be implemented in case of a long or short-term water deficiency, or in case of an emergency water shortage.

Higher stages will be implemented as shortages continue and/or if customer response does not bring about adequate desired water savings to address the shortage.

Each level represents an anticipated reduction in the supplies that would normally be available to the agency. These supply reductions could be the result of a variety of potential causes including natural forces, system component failure or interruption, regulatory actions, contamination, or any combination thereof.

The stages involve voluntary and mandatory conservation measures and restrictions, depending on the causes, severity, and anticipated duration of the water supply shortage. The locally appropriate shortage response actions that would be taken at each level to address the resulting gap between supplies and demands are described in the following section.

Water Shortage Contingency Plan Rivers ide Public Utilities 6 This section describes the shortage response actions that would be taken by RPU at each shortage level.

These actions have been grouped into categories including:
 Supply Augmentation Actions
 Demand Reduction Actions and Mandatory Use Restrictions  Operational Changes
Supply Augmentation
For long-range planning, RPU continues to evaluate opportunities for transfers, exchanges, and purchase of imported water to increase supply reliability. These programs are described in the supply sections of the UWMP. RPU has agreements in place to access imported supply if needed, and RPU has an emergency interconnection with Norco that could provide supply in an emergency. RPU is also able to receive 25 cubic feet per second (cfs) through a connection to Western.

RPU has a number of interties that can be used to provide additional supply during an emergency. Some of these are currently configured to deliver water from RPU to another system; however, during an emergency, they could be used as part of a regional water distribution strategy. The interties are shown in Table 3. Emergency Interties.

Demand Reduction Actions and Mandatory Use Restrictions RPU offers various rebates to encourage water use efficiency (such as ultra-low flush toilets, high- efficiency washing machines, etc.). RPU has a water rate structure that promotes water efficiency. The reduction goal is to balance supply and demand.

The demand reduction actions that will be implemented at each shortage level are shown in Table 5. The format of Table 5 is based on the standard submittal table defined by DWR. The column titled, “Penalty, Charge, or Enforcement” is a Yes/No field to characterize whether there is a penalty, charge, or enforcement action associated with implementing the demand reduction action. This field is a required field in the standard submittal table defined by DWR.

Water Shortage Contingency Plan Rivers ide Public Utilities 1 1

Operational Changes
RPU has identified operational changes that could be made to help address a short-term gap between demands and available supplies. These include:
 Increased monitoring and analysis of customer water usage  Reductions in flushing of h ydrants and dead-end lines  Expediting planned system improve ment projects that include reduction in water loss (e.g., replacement of water mains that are experiencing higher rates of leaks and breaks)  Activate conservation protocols
 Stop or minimize watering of medians and park areas with potab le water.  Stopping production of wholesale water for Norco and Western Additional Mandatory Restrictions
RPU has identified a series of restrictions that will be implemented at different shortage levels. These prohibitions are identified in RMC Code Chapter 14.22 and are included in the demand reduction actions in Table 5.

Emergency Response Plan
The Water Code requires that an agency’s WSCP address and plan for catastrophic water shortages.

This information can be found in the agency’s Emergency Response Plan (ERP). Each agency’s ERP can contain sensitive information related to potential vulnerabilities or impacts of natural disasters or malevolent acts. Therefore, these documents are not typically made publicly available.

Major hazards that can degrade the quality and/or impact the quantity of water available to the RPU water system include: regional power outages, earthquakes, liquefaction (i.e. high groundwater levels), floods, chemical spills, groundwater contamination, and terrorist acts. Some of these hazards could also adversely impact the distribution systems, such as the major transmission mains or reservoirs.

Interruptions to water supplies from any of the above-mentioned hazards may be limited to days or even months, except for groundwater contamination, which could last several years.

RPU has implemented several measures to improve the reliability of its water system. Actions taken to prepare for a catastrophe include:
 Establishing criteria for a proclamation of water shortage  Developing alternate sources of water supplies
 Establishing contacts and mutual aid agreement with other agen cies  Establishing an Emergency Response Team/Coordinator
 Preparing an Emergency Respons e Plan (ERP) (updated in September 2020)  Conducting mock exercises and d rills to evaluate and improve response procedures  Developing public awareness programs
RPU’s ERP may be activated whenever any of the following conditions exist:
 Natural disasters such as earthquake, flood, etc.
 Major loss of power
 Loss of water transmission lines , main breaks, or other major facilities  Water quality issues involving a "boil water" order or other major public relations/communication issues
 Emergency curtailment
 Disturbance affecti ng nearby utilities
 Hazardous spills
 Terrorist activities
Water Shortage Contingency Plan Riversi de Public Utilities 1 2
The ERP will guide damage assessment, record keeping, prioritization of repairs, and coordination with other City Departments. The goal is returning to normal operations as soon as practicable.

Typically, RPU's actions during voluntary rationing include a public information campaign and media outreach to encourage conservation. Typical emergency response actions to the above listed possible catastrophes may include the following:
 Assemble crisis management teams at pre-designated locations a nd Emergency Operations Center (EOC)
 Assess and document damaged facilities and repair or reactivat e as appropriate  Assess for signs of contaminati on, i.e., increase the frequency of monitoring  Deactivate cont aminated sources
 Install additional treatment facilities
 Community outreach e.g., public education, media outreach, boi l water advisories  Coordination with other City Departments, and other government agencies  Seek mutual aid assistance
 Drain contaminated reservoirs as quickly as possible
Inter-ties between water systems can be used to deliver water from other water retailers to assist RPU during short-term emergencies. RPU is also a member of the Water Agency Response Network (WARN).

RPU also participates in the Emergency Response Network of the Inland Empire (ERNIE). ERNIE is a water/wastewater mutual aid network within San Bernardino and Riverside counties. ERNIE meets monthly and provides regular training for utilities in emergency response and long-term emergency planning.

An assessment of each listed catastrophe and summarized description of previous responses and/or actions undertaken to prepare for such catastrophic events is described below.

4.5.1 Regional Power Outage
RPU is a municipally owned utility that provides both water and electricity within the City of Riverside.

RPU maintains a diverse power supply portfolio that includes long term base load and local generating facilities (LGF) and an increasing amount of renewable resources. With significant internal generation capability, RPU can maintain a high level of reliability in emergency situations.

Riverside’s system may be vulnerable to natural gas disruption. If natural gas interruption were to occur when RPU’s system demand reaches its peak, RPU may experience heightened stress to maintain service reliability to RPU customers.

Some wells in the Bunker Hill Basin are powered by electricity provided by Southern California Edison.

During electrical power outages, RPU will still be able to produce some potable water from the Gage wells and the Garner B well because they are or can be powered by gas engines. The water distribution system is entirely within the RPU electric service territory. Most of the pressure zones within the distribution system are fed by gravity from reservoirs. RPU is likely to have water in storage to meet an average day demand should a power outage occur.

4.5.2 Earthquakes
The City of Riverside is located close to two major earthquake faults: the San Andreas and San Joaquin.

Earthquakes pose potential significant risks to the RPU water system and could potentially result in water supply shortages and disruptions to the transmission/ distribution systems.

Groundwater produced from wells in the Bunker Hill Basin is conveyed using two major transmission mains that cross several earthquake faults before reaching the Linden Evans Reservoir in Riverside.

The City of Riverside has experienced some earthquakes in the past without significant water supply shortages or disruptions. Stronger earthquakes can result in major water service disruptions either due to facility damage or to power outages. In some cases, harmful microorganisms could migrate into the distribution system because of pipe breaks and/ or damage to water disinfection facilities. It could take several days (or more) to restore the water distribution system depending on the severity of damage.

Water Shortage Contingency Plan Riversi de Public Utilities 1 3
An earthquake in northern or central California could disrupt deliveries from the State Water Project to WMWD. The California Department of Water Resources (DWR) has estimated that in the event of a major earthquake in or near the Delta, regular water supply deliveries from the SWP could be interrupted for up to three years, posing a substantial risk to the California business economy. Current planning efforts for these potential events are described in documents prepared by DWR, MWD, and WMWD.

4.5.3 Liquefaction
Another potential hazard related to earthquakes is soil liquefaction. Liquefaction is a phenomenon that occurs in loose, saturated, granular soils when subjected to strong ground movement. High groundwater levels shallower than the threshold (between 30 and 50 feet below ground surface) may at some locations increase the potential for liquefaction during very strong earthquakes. Some of the wells in the North Orange area of the Riverside Basin are located in areas prone to liquefaction.

RPU also has wells located in the lower part of the Bunker Hill Basin (i.e. the pressure zone), which can be vulnerable to liquefaction. Some segments of RPU's major water transmission mains from the Bunker Hill Basin to the Linden Evans Reservoir are located within potential liquefaction zones.

RPU cooperated with the San Bernardino Basin Area Basin Technical Advisory Committee (BTAC) to develop and implement a "high groundwater" mitigation plan to reduce the potential for liquefaction in the Bunker Hill Basin. During the recent past, the Western San-Bernardino Watermaster has not declared a "high groundwater" risk. Groundwater levels are lower in the Bunker Hill Basin due to climactic conditions and increased pumping. Should high groundwater pose a threat in the future, RPU will assist by pumping additional groundwater from the pressure zone, in accordance with the rules and regulations of the Western-San Bernardino Watermaster.

4.5.4 Floods
Some RPU wells are located within the flood plain of the Santa Ana River and vulnerable to flooding. In 1995, floods washed away the superstructure of the Gage 21 well, and the sub-surface portion of the well was subsequently abandoned. The Gage 98-1 well replaced the Gage 21 well with funding assistance from the Federal Emergency Management Agency (FEMA). The other wells most vulnerable to flooding include some Warren Tract wells. RPU replaced some of the Warren Tract wells upstream with the Cooley J well.

In 1999, the Seven Oaks Dam, which is located near the headwaters of the Santa Ana River, became operational and reduces the magnitude, frequency and vulnerability of flooding while increasing available water rights.

RPU has implemented many measures in order to minimize adverse impacts of flooding on groundwater contamination. For example, RPU increased the length of well seals for newer wells to greater depths than required by the State of California water well standards. RPU also screens newer wells generally deeper than 200 feet below ground surface. Additional chlorination stations were added further upstream of the major transmission mains thereby increasing the disinfection contact time. Prior to 2003, wells in the North Orange area pumped directly into the distribution system. The North Orange wells have now been connected by a major transmission main to the Linden Evans Reservoir for increased disinfection contact time.

Potential hazards from floods are not limited to physical damage and/ or loss of water infrastructure.

Studies have found that more than half of the waterborne disease outbreaks in the United States in the past 50 years were preceded by heavy rainfall. Outbreaks due to surface water contamination, which accounted for approximately 24-percent of all outbreaks, were associated with extreme precipitation occurring during the month of the outbreak and one month prior. Outbreaks due to groundwater contamination, which accounted for approximately 36-percent of all outbreaks, were associated with extreme precipitation occurring within a three-month lag preceding the outbreaks.

4.5.5 Groundwater Contamination
Water Shortage Contingency Plan Rivers ide Public Utilities 1 4
Potential hazards that could result in groundwater contamination include migrating contaminant plumes, chemical spills, agricultural return flows, leaky underground storage tanks, and septic systems. Chemical spills and leaking underground storage tanks initially tend to affect a small number of wells, whereas contaminant plumes, agricultural return flows, and septic systems may impact regional aquifers.

Previous improper waste disposal practices have created several groundwater contamination plumes that impact a number of RPU wells. Groundwater contamination can potentially interrupt water supplies for an extended period. However, some groundwater contamination/ chemical spills have Potentially Responsible Parties (PRP) who can be made to pay mitigation costs. PRPs are mitigating groundwater contamination due to organic solvents thus assuring continued availability and reliability of water supplies affected by those plumes.

In 2001, RPU reached an agreement with manufacturers of the pesticide dibromochloropropane (DBCP) that has contaminated wells in the Riverside Basin. Under the agreement, DBCP manufacturers agreed to pay the capital costs and 40 years of operating and maintenance costs of facilities to remove DBCP from production wells. RPU has been reimbursed for Granular Activated Carbon (GAC) treatment plants that enable RPU to produce additional water from wells previously abandoned due to contamination.

In the late 1980s and early 1990s, water produced from wells connected to the Waterman Transmission main were used to blend impaired water produced from the Gage wells to meet potable drinking water standards. However, water quality within the Gage wells has improved since the Responsible Parties constructed wellhead treatment facilities and replaced shallow wells with deeper ones. The treatment facilities are capable of removing a range of contaminants.

Seismic Risk Assessment and Mitigation Plan
Water Code Section 10632.5 requires agencies to assess seismic risk to water supplies as part of their WSCP. The code also requires a mitigation plan for managing seismic risks.

In lieu of conducting their own seismic risk assessment, suppliers can comply with the Water Code requirement by submitting the relevant local hazard mitigation plan or multi-hazard mitigation plan.

RPU participated in the development of the Riverside County Local Hazard Mitigation Plan, which was updated in 2018. The Riverside County LHMP is available on the Riverside County web site at https://rivcoemd.org/LHMP.

The Riverside County LHMP includes an assessment of the region’s vulnerability to a broad range of hazards, including earthquakes. It also describes mitigation strategies and actions to reduce the impacts of a seismic event.

RPU continues to include seismic risk assessment in its planning process for system improvements.

Some elements of RPU’s approach to mitigation seismic risk are:
 Several of RPU’s reservoirs ar e outfitted with seismically actuated valves.  RPU restrains the joints of it s distribution pipelines and utilizes welded steel pipes for its transmission mains.
 RPU is in the process of perfo rming condition assessments and evaluating its reservoirs for seismic vulnerability.
 RPU uses flexible seismic joi nts on its pipelines where they transition from underground into highway bridge structures.
 RPU recently replaced Evans Rese rvoir to meet current seismic codes.  RPU recently replaced the roof on Linden Reservoir to meet current seismic codes.

Shortage Response Action Effectiveness
RPU has estimated the effectiveness of shortage response actions in terms of reducing the gap between expected supplies and demands. These estimates were developed using industry resources and observations from recent operating history at the agency. These estimates have been included in Table

5. Water Shortage Contingency Plan Rivers ide Public Utilities 1 5

Timely and effective communication is a key element of WSCP implementation. RPU will need to inform customers, the general public, and other government entities of WSCP actions taken during a water shortage (either one derived from the Annual Assessment, or an emergency or catastrophic event).

The communication protocols to be used by RPU at each shortage level are summarized in Table 6.

Water Shortage Contingency Plan Rivers ide Public Utilities 1 7

The Water Conservation Ordinance states that any violation shall be subject to enforcement by issuance of an administrative citation pursuant to Chapter 1.17 of the Riverside Municipal Code. Prior to issuance of an administrative citation, the City shall give one courtesy notice requesting voluntary correction of the violation. The City Manager, or his or her designee, may enter into a written agreement with a customer to resolve any violation provided that such agreement is consistent with the purpose and intent of the Water Conservation Ordinance.

RPU has mechanisms in-place for monitoring compliance with actual mandated reductions. Water sales to customers are metered and billed monthly. RPU implements a meter maintenance program to assure accuracy. Collected revenues from water sales are incorporated into the monthly financial reports produced by the RPU Finance Section. RPU’s billing system can be used to provide customers with reports of their water usage for current year and previous years. The billing software can also be used to evaluate compliance with mandated reductions.

RPU has the capability to determine reductions in water production. RPU maintains a comprehensive Supervisory Control and Data Acquisition (SCADA) system to monitor and control the water distribution system. All production wells are metered and monitored. The SCADA system is capable of recording potable water production and water levels within potable water reservoirs. Water levels of selected wells are regularly monitored and charted. Flow meters installed at pump stations and booster stations can be read automatically through the SCADA system to determine usage.

Water Rule No. 15 includes penalties for excessive water usage. According to Water Rule No. 15, "Whenever it appears to the Director that water delivered by the Water Utility is being used in violation of the terms of this Rule, he [/she] shall give written notice to the person so wasting water of his [/her] intention, after a reasonable time to be therein stated, to shut-off the water supply to the Person's Premises".

Appeals and Exemption Process
The City has processes in place for appeals and exemptions from penalties for violations. These are identified in the RMC, Chapter 1.17.

This section describes the legal authorities that the agency relies upon to implement the shortage response actions and the associated enforcement actions.

The current version of the Water Conservation Ordinance, which is Chapter 14.22 of the RMC, is attached to this document.

In accordance with Water Code Chapter 3 (commencing with Section 350) of Division 1 general provisions regarding water shortage emergencies, RPU shall declare a water shortage emergency in the event of a catastrophic interruption in supply.

RPU shall coordinate with any city or county within which it provides water supply services for the possible proclamation of a local emergency under California Government Code, California Emergency Services Act (Article 2, Section 8558). Including a list of and contacts for all cities or counties for which the Supplier provides service in the WSCP, along with developed coordination protocols, can facilitate compliance with this section of the Water Code in the event of a local emergency as defined in subpart (c) of Government Code Section 8558.

The cities and counties in the RPU’s service area are shown in Table 7.

This section describes the anticipated financial consequences to RPU of implementing the WSCP. The description includes potential reductions in revenue due to lower water sales and increased expenses associated with implementing the shortage response actions.

Potential financial impacts could include
 Reduced revenue from reduced water use
 Increased staff costs for tra cking, reporting, patrolling, and enforcing restrictions  Economic impacts associated wi th water-dependent businesses in the service area Potential mitigation measures may include
 triggering of drought rate structures or surcharges
 using financial reserves
 reducing operation and maintenance expenses

RPU is fortunate as a water provider in California in that it owns, operates and maintains its own water supply and is not typically dependent on imported water from outside sources. RPU has responded to past droughts by continuing to offer a wide variety of water use efficiency and conservation programs for its customers in an effort to conserve its water resources. In addition, RPU has increased its drought messaging to its customers, increased community educational awareness and leveraged funding from MWD to provide incentives for water conservation programs such as turf removal.

RPU’s long range water supply planning includes significant contributions of both conservation and recycled water. The behavioral changes instituted through conservation and water use efficiency should have some permanent impact. Changes in landscape patterns and uses will have permanent and on- going impacts to water use. Continuing conservation measures could negatively impact RPU’s revenues and will be addressed as needed during analysis of cost of service.

RPU's typical water rate includes the following components: a fixed monthly charge, a prorated commodity charge based on consumption with increasing marginal rates and adjustments for seasonality, an energy factor adjustment, a surcharge for customers not within City Limits, and a Water Conservation and Reclamation surcharge. Revenue from fees such as fixed monthly charges, development related fees, and the backflow protection program will not be impacted by reduction in water usage due to droughts.

RPU has many options to cushion reduction in revenues due to reduced demand by its retail customers.

RPU maintains reserves that can offset minor revenue impacts. In addition to these liquid assets, RPU has an additional 12 to 18 months of operating revenue in the form of non-liquid assets such as land and buildings. Other potential measures that RPU can implement to mitigate some revenue impacts due to Water Shortage Contingency Plan Rivers ide Public Utilities 1 9
shortages include adjusting the water rates, using water that has been stored in reservoirs, and refinancing existing bonds or issuing new bonds.

RPU seeks to maintain flexibility to adjust expenditures during drought conditions as well. Some expense categories such as purchased energy, treatment costs, and operations and maintenance will be reduced as revenue from water sales decrease. Reduced groundwater production will also lead to reduced energy costs. RPU can reduce or avoid some water treatment costs by choosing to operate wells that require the least amount of treatment. RPU can also pump the most efficient wells to further reduce energy costs. RPU can investigate additional energy savings from switching to cheaper rate schedules based on time of use by taking advantage of distribution system reservoir storage. Lastly, RPU can delay capital expenditures.

This section describes how the agency will monitor and report on implementation of the WSCP. RPU has the capability to determine reductions in water production and consumption. RPU maintains a comprehensive SCADA system of the water distribution system. All production wells are metered and monitored. The SCADA system is capable of recording potable water production and water levels within potable water reservoirs. Water levels of selected wells are regularly monitored and charted. Flow meters installed at pump stations and booster stations can be read automatically through the SCADA system to determine usage. RPU can also use billing data to monitor changes in consumption.

RPU will gather data on key water use metrics and use the data to evaluate the effectiveness of response actions in achieving their intended water use reduction purposes. RPU will also gather data on customer compliance to evaluate the effectiveness of enforcement actions.

RPU will monitor water use by customers using its billing systems and operational control systems to monitor production and consumption. RPU measures and determines the actual water savings made by implementing each stage of the WSCP by relying on water meters that record the production and consumption of water. Each level of the WSCP has an associated target reduction for metered water use.

RPU will monitor the implementation of this plan to evaluate its effectiveness as an adaptive management tool. The monitoring and reporting program described in Section 9 will provide information on the effectiveness of the shortage response actions during any shortage levels that may be invoked. If RPU determines that the shortage response actions are not effective in producing the desired results, it will initiate a process to refine the WSCP.

RPU will consider the addition of new shortage response actions or changes to the levels when shortage response actions are implemented. Suggestions for refinements will be collected from agency staff, customers, industry experts, and the general public. RPU will work with wholesale customers to share data and suggestions for refinement to identify opportunities to increase the effectiveness of the WSCP while maintaining alignment with other agencies in the region when possible.

RPU will review the WSCP’s description of procedures for the Annual Assessment each year while preparing the Annual Assessment and adjust as needed.

RPU has distinguished swimming pools and spas as recreational water features, while non-pool and non- spa water features are considered decorative water features. This distinction is used in the shortage response actions because decorative water features have the potential to use recycled water, while pools and spas (recreational water features) must use potable water for health and safety considerations.

A splash pad shall be defined as a recreational feature and includes any pavement or sidewalk area that is part of the splash pad. Operation of a splash pad is not prohibited by this ordinance as an unreasonable use of water.

RPU adopted this WSCP with the 2020 UWMP. The UWMP and WSCP were made available for public review during May of 2021. A public hearing was held on June 14, 2021 to allow public input on the draft UWMP and the WSCP.

The RPU board of directors adopted the UWMP and the WSCP at a meeting on June 14, 2021, and the City Council adopted them on June 22, 2021. The resolution of adoption is included as an attachment.

This WSCP was submitted to DWR through the WUEData portal before the deadline of July 1, 2021.

This WSCP will be available to the public on the agency’s web site. Notice will be provided to cities and counties in the service area that the WSCP is available on the agency’s web site.

If RPU identifies the need to amend this WSCP, it will follow the same procedures for notification to cities, counties and the public as used for the UWMP and for initial adoption of the WSCP. The draft amended WSCP will be made available for public review, and the agency’s governing board will hold a public hearing to receive comments on the draft amended WSCP. Once RPU’s governing board adopts the amended WSCP, the amended plan will be submitted to DWR and the California State Library, and it will be made available to the public and the cities and counties in the service area through placement on the agency’s web site.
