- The City of Big Bear Lake's Water System Facilities Automation Project Phase II will replace four of its existing pumping plant controls with new variable frequency drive units and water meters, upgrade existing telemetry or install new telemetry components, install three new production well meters, upgrade six other production well meters by adding SCADA and Radio Read connections, and upgrade its Main Base SCADA Server. These improvements will allow the City to more accurately control and monitor water use and fluctuations. The upgrades will also improve reporting and alarm abilities, and allow for faster responses to problems and emergencies, preventing further water loss. This project aligns with goals in the City’s five-year Capital Improvement Plan.
- The West Basin Municipal Water District’s "Regional Landscape Water Use Efficiency (WUE) Program" will assist West Basin's member agencies to better improve regional water management practices by converting a total of 450,000 square feet of grass turf with water conserving landscape alternatives. West Basin has observed a high demand in water consumption stemming from over irrigation at golf courses, commercial landscaping, parks, and residential lawns. This high use consumption is not only dependent on the ETo of turf grass but also on the misapplication by consumers (i.e. over watering), particularly during the dry summer months. The Regional Landscape WUE Program's goals are to curtail the use of imported water, energy consumption, and greenhouse gas emissions within West Basin's service area through the implementation of this project and better manage these critical resources.
- South Coast Water District Advanced Metering Infrastructure Implementation Program Phase 1 Project. South Coast Water District in southern California will upgrade 3,008 Automatic Meter Readings (AMR) water meters to Advanced Metering Infrastructure (AMI) meters. The project is expected to result in 90 acre-feet of water savings annually. The project will implement adaptation strategies from the WaterSMART Colorado River Basin Study.
- West Basin Municipal Water District Water Use Efficiency Data Study Final Project Report. In 2016, West Basin took an innovative approach to this project. Before proceeding with the Plan development, West Staff took a step back and developed a 2-step process. In step 1, West Basin hired a consultant to help identify the components to include in the Plan. This approach took a bit longer, but was well worth the effort. West Basin identified key drivers that would need to be included in the plan, such as how to use “big data”, identifying water conservation legislation and developing a stakeholder driven process. Once these drivers were identified, West Basin hired its second consultant to develop the Plan. As the process rolled-out, West Basin staff came to learn pretty quickly that the Plan was actually a data study.
- Helendale Community Services District AMI Smart Meter Installation Program - The Helendale Community Services District in southern California will install 400 Advanced Metering Infrastructure (AMI) Smart Meters, 400 AMI radios, a radio tower, and all necessary hardware to upgrade their outdated meters. AMI technology will assist the District in water planning, water conservation efforts, and enhance customer service. The project is part of the District’s Capital Improvement Plan.
- City of Big Bear Lake Department of Water and Power Division Well Field Solar Project - Under this Agreement, the City of Big Bear Lake Department of Water and Power (DWP) will install 700 solar panels to provide power to DWP’s Division Well Pumping Plant Nos. 2,5,6,7, & 8. The solar panels will be non-reflective and installed at a steep angle on ground-mounted stands approximately three feet above finished grade. Each solar panel will connect to an inverter and one master meter will be installed to deliver electricity to the Bear Valley Electrical Service. The solar panels will have a capacity of 220 kilowatts and are expected to generate 400,000 kilowatt-hours of energy annually. The Project site is located between the Big Bear Airport and Baker Pond. Major components of this project are anticipated to include 700 solar panels, 4-12 inverters, one master meter, minor grading, and 1,200 linear feet of 6-foot high slatted chain link fence.
- City of Big Bear Lake Variable Frequency Drive Motor Starter Units and Water Meter - Under this Agreement, Recipient will purchase and install, Variable Frequency Drive (VFD) Motor Starter Units and Water Meters for customers within the Bear Valley basin in San Bernardino County, California. Major components of this project include: • New pressure and water level sensing devices and displays • Update of the telemetry control system • Regulate the pumping of each well based on system needs and aquifer water levels.
- Western Municipal Water District - Western is pioneering a new approach to develop a Water Use Efficiency Master Plan (Plan). This approach will include detailed customer preferences and attitudes beyond what is typically included in these types of plans. By working with a local university, Western will obtain data that will inform the development of water use efficiency programs and allow for much more detailed and targeted marketing of programs. Traditional plans use basic demographic information about customers, but do not usually ask customers about their beliefs and attitudes toward water use efficiency, nor do they account for cultural differences in messaging beyond a cursory effort. The Plan will combine in-depth information on stakeholder beliefs, attitudes, and cultural differences with a comprehensive outreach plan that will help increase water use efficiency awareness and program participation. The Plan will help Western design more relevant water use efficiency programs and outreach to make more efficient use of existing water supplies.
- Municipal Water District of Orange County's Spray-to-Drip Conversion Pilot Project (January 2018) -- This project encouraged replacement of high-water-using spray heads with efficient low-water-using drip irrigation at residential and commercial properties. The objective of this Program is to attain quantifiable and sustained water savings and improved water management, resulting in an increase in energy efficient water management and promotion of activities that support water supply sustainability. The Program also expands District's existing suite of landscape rebate opportunities beyond Smart Timer Rebates, Rotating Sprinkler Nozzle Rebates, and Turf Removal. Total water savings combined for both commercial and residential sites is estimated to be 64 AF/year over a 10-year period.
- Chino Basin Water Conservation District Residential Weather Based Irrigation Controller (WBIC) Installation Program (October 2017) – This program installed 300 WBICs at residential locations to help reduce water demand by about 40 acre-feet per year. WBICs provide an appropriate watering schedule, adjust for weather changes, and irrigate based on the needs of the landscape and soil conditions.
- City of Big Bear Lake Advanced Metering Infrastructure (AMI) Program (September 2017) – The City’s Department of Water and Power aims to replace 15,500 aging manual-read meters with AMI meters and radios. An AMI system allows for better tracking of water system demands in real time to assess the effects of conservation measures and identify where additional conservation may be possible. The system also reduces water waste through early leak detection. The scope of this project was the replacement of 5,000 meters and radios installed between July 2015 and March 2017. City staff installed and programmed the AMI installations, saving more than $200,000 in installation costs. The project is estimated to save approximately 43 acre-feet per year.
- City of Big Bear Lake Boulevard Pipeline Replacement Project (September 2017) – This project included the replacement of 4,000 linear feet of 12-inch steel pipeline with new 12-inch PVC pipe. Commercial water service lines to 39 businesses were also replaced, as well as two commercial fire services and eight hydrants. Approximately 17 acre-feet per year are expected to be saved through the elimination of leaks associated with the 69 year-old steel pipeline. With reduced pumping demands associated with the leaks, the project is also saving more than 120,000 kWh per year.
- Metropolitan Water District of Southern California, California Friendly Turf Replacement Incentive Program - Phase 2 Southern California (December 2016) - The California Friendly® Turf Replacement Incentive Program - Phase 2 (Program) transformed 1.07 million square feet of thirsty turf landscapes to California Friendly landscapes with climate-appropriate plants, efficient irrigation, permeable surfaces to allow rainwater infiltration, and mulch to preserve soil moisture. These 1.07 million square feet have included residential and commercial projects throughout Metropolitan's 5,200 square mile service area. The program provided 1,400 acre-feet in lifetime water savings, increased acceptance of non-turf lawns, and continued market transformation. Because a significant portion of Metropolitan's water supplies are imported from the Colorado River and Bay Delta, this program also provided benefits for energy efficiency, critical habitat for threatened and endangered species, and water markets.
- Metropolitan Water District of Southern California, Southern California Friendly Turf Replacement Incentive Program - Phase 2-A Southern California (December 2016) - The California Friendly® Turf Replacement Incentive Program - Phase 2-A (Program) transformed 1.09 million square feet of thirsty turf landscapes to California Friendly landscapes with climate-appropriate plants, efficient irrigation, permeable surfaces to allow rainwater infiltration, and mulch to preserve soil moisture. These 1.09 million square feet have included residential and commercial projects throughout Metropolitan's 5,200 square mile service area. The program provided 1,422 acre-feet in lifetime water savings, increased acceptance of non-turf lawns, and continued market transformation. Because a significant portion ofMetropolitan's water supplies are imported from the Colorado River and Bay Delta, this program also provided benefits for energy efficiency, critical habitat for threatened and endangered species, and water markets.
- Los Angeles Department of Water and Power Landscape Incentive Program (CII) Project Los Angeles, California (December 2016) - Established in 2009, the LADWP’s Commercial/Industrial Drought Resistant Landscape Incentive Program provides financial incentives of $1.00 per square foot of turf removed and replaced with California Friendly landscapes, including mulch and drip water irrigation systems. Funding from this Grant was for converting 3,000,000 square feet total turf, expecting a water savings of 229.34 Acre Foot/Year (AFY). LADWP began implementing the Grant on October 1, 2011, and when the Grant termed out in September 30, 2013, an extension was granted until September 30, 2016. The conditions of the Grant were met with the 7th, semi-annual invoice (10/01/14-03/31/15). 94 Turf projects were completed during the course of the Grant for a total of 3,690,550 square feet of turf converted. Of the 3,690,550 square feet of turf that was removed, 313,413 square feet were completed beyond the requirements of the Grant.
- Elsinore Valley Municipal Water District, Instant Hot Water Recirculating System Rebate (June 2016) - In an effort to aid customers in reducing their indoor water use, EVMWD sought funding to expand its rebate program to include Instant Hot Water Recirculation Systems. EVMWD believes this rebate program would motivate customers to install this system, and save a potentially significant amount of water throughout the service area. These systems cost approximately $180-$200 at local hardware stores such as Lowe’s and Home Depot, and can be installed directly onto an existing traditional water heater by the homeowner or a plumber. The installation of an Instant Hot Water Recirculating System enables hot water to run almost immediately from faucet and shower when needed, dramatically reducing the amount of cold water. According to one manufacturer, an average home has approximately 125 feet of ¾-inch pipe, which holds 3.14 gallons of water. If hot water is used 10 times per day, 31 gallons of water is wasted running the faucets/shower to achieve hot water. In just one year, this equals about 11,461 gallons of water.
- Municipal Water District of Orange County Online Irrigation Base Schedule Calculator (April 2016) - The Project targets all consumers with automatic irrigation systems, by offering an irrigation base schedule software tool based on the actual, on-site irrigation equipment application (precipitation) rate, plant material, slope sun exposure, and soil type. The Calculator develops customized irrigation base schedules to be entered when programming either conventional or smart irrigation timers. The Calculator can also utilized to provide the information as a monthly schedule. In addition to the water savings attributed to the use of the Calculator as a standalone tool, it can also be utilized to ensure optimum water savings and program success for program such as the Smart Timer Rebate Program and the California Sprinkler Adjustment Notification System (CSANS). Ultimately, this tool will be made available for use by water agencies throughout the state. Based on similar irrigation management projects, approximately 39 gallons per day can be saved through proper irrigation management. Anticipating the Calculator will be used by at least 50 new people per month, the associated water savings goal is 26 acre-feet per year (AFY) or 131 lifetime acre feet (AFL) over the anticipated five-year life. Actual water saving resulted in 31 AFY or 153 AFL.
- City of Burbank Johnny Carson Park Irrigation Retrofit (April 2016) - The Johnny Carson Park Irrigation Retrofit project will reduce potable water demands by retrofitting the antiquated and inefficient landscape irrigation system, and converting from potable water to 100% recycled water. The project supports the City’s Recycled Water Master Plan and Sustainable Goals.
- City of Corona Centralized Irrigation Controllers for Targeted District Schools Final Project Report (March 2016) - The City of Corona Department of Water & Power (DWP) Project included the installation and procurement of centralized weather-based irrigation controllers at five separate elementary school sites selected in the Corona-Norco Unified School District (CNUSD). Installation consisted of state-of-the art, wireless weather-based centralized controllers (also called evapotranspiration or “ET” controllers) to create a centralized network throughout an existing irrigation system. The upgrade to real-time ET controllers allows District staff to access the irrigation system from their personal computers and stop, start, adjust or even alert staff immediately when unusual increases in water flow occur. The ET controllers will automatically shut down the affected line until school (or District) staff can respond to save water, time, and resources. CNUSD is one of the City’s largest water customers; reducing their water consumption will help towards the City achieving its water conservation goals.
- Metropolitan Water District of Southern California High Efficiency Clothes Washer Incentive Program (February 2016) - The High Efficiency Clothes Washer Incentive Program (Program) influenced 13,292 residential customers to purchase high-efficiency clothes washers. The Program increased Metropolitan's incentive from $85 to $110 per unit, which reduces the cost barrier for customers between traditional washers and more efficient washers. The Program only funded high-efficiency clothes washers with a water factor of 4.0 or less. Incentives were provided through Metropolitan's regional rebate program, SoCal Water$mart. Based on studies of water savings for high-efficiency clothes washers, the Program provided 6,1 00 acre-feet in lifetime water savings. The Program also provided direct energy savings from the high-efficiency clothes washers. In addition, because a significant portion of Metropolitan's water supplies are imported from the Colorado River and Bay-Delta, this program also provided benefits for energy efficiency, critical habitat for threatened and endangered species, and water markets.
- Municipal Water District of Orange County Water Efficient Site Certification and Smart Timer Rebate Project (December 2015) - The Water Efficiency Site Certification and Smart Irrigation Rebate Project (Project) provides rebates for the installation of residential water efficiency improvements in over 700 households, including advance irrigation timers and rotating nozzles. The Project also provided single family sites with indoor and outdoor audits to identify the importance of installing water savings deceives and other water saving improvements. As a goal, the Project was to facilitate the installation of 576 residential smart timers and 23,400 rotating nozzles with installation verification. Additionally, the Project used a Site Water Use Audit Project format to perform up to 1,000 comprehensive residential audits. The single-family indoor and outdoor audits identified the areas of the property where water based improvements could be made, and as part of the audit any applicable rebates for improvements was recommended.
- Municipal Water District of Orange County CII Performance-Based Water Use Efficiency Program (December 2015) - The Commercial/Institutional/Industrial (CII) Performance-Based Water Use Efficiency Program (Program) was developed by the Municipal Water District of Orange County (MWDOC) to offer Commercial, Industrial, and Institutional (CII) and Large Landscape Turf Removal (LL) sites with incentives in the form of rebates to assist in the reduction of water use. The projects utilized a comprehensive process approach for the oneto-one replacement of high water using devices for water efficient devices. At LL sites, comprehensive landscape projects may include any combination of the following components: the replacement of non-functional turfgrass with climate-appropriate, non-invasive, California-Friendly landscapes or permeable surfaces, conversion of high-water-using spray heads to rotating nozzles, upgrade of conventional irrigation timers to smart timers, and irrigation management services. For CII device replacement the Program facilitated rebates by utilizing Metropolitans southern California Regional rebate Program and for LL project incentives were facilitated by MWDOC’s Turf Removal Program. Through a combined effort across all Program sectors the water savings goal is 113 acre-feet-per year (AFY).
- Metropolitan Water District of Southern California 2011 Innovative Conservation Program Final Project Report (December 2015) - In 2008, the Metropolitan Water District of Southern California (Metropolitan) signed an agreement (08FG350247) with the United States Bureau of Reclamation (Reclamation) for the Innovative Conservation Program (ICP) for $228,000. This agreement was amended several times in the subsequent years, including change of agreement number to the current R08AP35247 and increase of Reclamation funds to $248,000. The ICP provided grant funding to explore the water and energy savings potential and practicality of innovative water conservation technologies. Through this agreement, seven (7) research projects were completed totaling almost $384,500 of combined funding from Metropolitan and Reclamation. Some of the funding provided through this agreement was also used to fund projects on the subsequent 2013 ICP. Each project submitted a Final Report that includes information on project design and accomplishments including water and energy efficiency/savings.
- Santa Ana River Watershed LiDAR/Infrared Imagery Landscape Mapping Demonstration Project (November 2015) - The purpose of the project was to demonstrate the use of color orthophotography and LiDAR for identification of areas of irrigated plant types and locations. The identification occurs by matching color cells from the color orthophotography and the height from the LiDAR data. LiDAR creates a contour map including the buildings and plants. There were three areas of study to determine the feasibility of identifying irrigated landscapes. Each area was located in the Santa Ana Watershed and represented urban, mixed use, and predominately agriculture land use. This improves water use efficiency by providing an accurate ground picture of irrigated land when applying tiered water rates. Irrigation of landscaping within the Santa Ana Watershed accounts for approximately 70% of the water delivered to the average customer.
- City of Corona Advanced Metering Infrastructure Final Project Report (August 2015) - The City of Corona Department of Water & Power proposed to convert outdated water meters into "smart" meters with advanced metering infrastructure (AMI) technology capabilities. The final project encompassed a total of 1,311 new meters and existing meters retrofitted with the AMI technology. A total of 1,213 meters were either replaced or retrofitted within the Eagle Glen area. Replaced meters located within the Eagle Glen area are now able to be read via data collectors, with remaining meters retrofitted for real-time data for a system water balance check to this area. The balance of 98 AMI meters were placed elsewhere throughout the City, in difficult to access areas that were completely inaccessible by meter readers, previously resulting in estimated readings. These can now be read using in-house data collection software on a regular basis. The project expands the City's current water conservation efforts by utilizing advanced technology advancements in metering infrastructure as a cost-effective means of improving operational efficiencies, provides accurate meter reading data for maximum revenue optimization, and aids as a tool in identifying potential waste location of a precious resource, water.
- National Water Resources Institute Conservation Potential of Salinity Mitigation Strategies (June 2015) - The URS Corporation and its subconsultants, PlanTierra and Harvey Economics, were retained by the National Water Research Institute to conduct an extensive literature review in order to: 1) estimate the water savings that may be realized when salinity levels are reduced, specifically for large landscape irrigation applications and in the residential, commercial and industrial sectors where water softeners and reverse osmosis devices are being utilized; 2) estimate the associated dollar savings when salinity levels are reduced; and 3) identify potential cost effective water saving approaches and future studies. The information contained within this study may be adapted for any area; however, the focus was on the Metropolitan Water District of Southern California’s service area. Appendix A
- City of Torrance Stormwater Basin Enhancement Project (July 2015) - The stormwater from the City of Torrance that requires treatment mostly comes from the watershed area that is tributary to the Amie, Henrietta and Entradero stormwater detention basins. The Stormwater Basin Enhancement Project provided the following: 1) Amie Basin: passive wetland treatment, native habitat restoration and additional stormwater infiltration; 2) Henrietta Basin: passive wetland treatment, additional stormwater infiltration and habitat restoration, access pathways and educational opportunities; and 3) Entradero Basin: additional infiltration, habitat restoration and improved public access without affecting the existing park and baseball activities and retrofit of existing park irrigation to recycled water.
- Inland Empire Utilities Agency Turner Basin Recharge Improvements Project (July 2015) - The project is part of an integrated strategy to increase local water supplies and minimize purchases of water from the Bay-Delta. Existing facilities at the Turner Basin recharge site were expanded and improved to more efficiently be able to capture and recharge local rainfall runoff and recycled water. The water savings was expected to be 2,400 acre feet per year (afy) as a long-term average of 20 years or more. The water will be recharged into the Chino Basin groundwater aquifer and managed for conjunctive use. Conjunctive use provides flexibility to manage and minimize imported surface water supplies by “banking” water in the subsurface or otherwise drawing on groundwater supplies to offset surface deliveries.
- Bureau of Reclamation Weather- and Soil Moisture-Based Landscape Irrigation Scheduling Devices (August 2018) - Since 2004, Reclamation has maintained a report on weather and soil moisture-based landscape irrigation controllers (smartcontroller). To be considered a smartcontroller, an irrigation scheduling device must automatically schedule/adjust irrigation as a function of weather (ET) or soil-moisture conditions. The purpose of the report is to: provide some technical background on how a smartcontroller functions; summarize smartcontroller certification and testing processes; and present an unbiased overview of available products. Though many will find the content compelling, water agencies developing a smartcontroller incentivization program might find the report particularly useful. This sixth edition of the report includes information on smart irrigation controller products from 24 companies.
- Council for Watershed Health Elmer Paseo Stormwater Improvements Project (May 2015) - Through this project, also known as the Green Alleyway Landscape Retrofit for Water Conservation project, the Council for Watershed Health successfully revitalized a paved alleyway used for stormwater conveyance by converting it to a green space with bioswales, pervious walkway, native plants, green walls, solar-powered drip irrigation, monitoring equipment, and interpretive signs. The project is now a natively-planted pocket-park in a park-poor low-income community in Los Angeles that captures dry weather and wet weather flow for infiltration to the San Fernando Groundwater Basin. High flows pass through the Paseo bioswales, but do receive treatment by green infrastructure that diminishes pollutant loading. The native plants draw local pollinators and provide respite for the neighborhood. Interpretive signage provides educational information and monitoring for the project. Tour groups from professional and government groups, as well as classes of students, are regular visitors to learn the benefits of green infrastructure retrofits for water conservation. The Elmer Paseo is engineered to capture all dry-weather flow from 7 acres of residential land, and up to 6 acre-feet of storm water during an average rainfall year.
- Municipal Water District of Orange County Industrial Process Expansion (March 2015) - The Municipal Water District of Orange County (MWDOC) developed a program to help industrial businesses reduce their water use and associated wastewater flows. The Industrial Process Water Use Reduction Program provides businesses in the Food Processing, Textile Manufacturing, Metal Plating, and Electronics Manufacturing industries (sectors with the largest potential for water savings) with engineering surveys to identify water saving process improvements and offers financial incentives to help implement recommended changes. Survey participants received customized Survey Reports that summarized recommended retrofits and changes to operating practices that will result in significant water savings. Estimated costs, savings and payback information were also included, along with "next steps" on how to implement the recommended improvements. Incentive payments from The Metropolitan Water District of Southern California and MWDOC were offered to companies successfully implementing long-term process improvements. The Industrial Process Expansion project continued the efforts of this program to include three additional comprehensive surveys, five additional MWDOC incentives, and engineering assistance to implement process changes for two companies. The overall water savings project goal was 377 acre feet of water per year.
- Municipal of Water District of Orange County OC Smart Timer Rebate Program (March 2015) - The OC Smart Irrigation Timer Rebate Program was developed by the Municipal Water District of Orange County (MWDOC) to offer residential and commercial sites rebate incentives to encourage irrigation controller device retrofits. Weather-based irrigation controllers (commonly referred to as Smart Timers) were targeted for this program because of their significant potential for water savings. To implement this project, MWDOC employed a rebate-format implementation process that included marketing/promotion; participation guidelines and procedures to add this project into the regional rebate administrator process; development of customer service protocols; project data compiling; device installation verification; a water savings evaluation; quarterly and final reporting; and quality control procedures. MWDOC's goals were to install 475 residential timers and 800 commercial timers, with an overall project water savings goal of 560 acre-feet of water per year over a 10-year term. From project launch in September 2011 through the end of September 2014, a total of 2,072 residential timers and 1,803 commercial timers were installed, yielding a potential water savings of 783 acre-feet of water per year. The implementation rates far exceeded the project goals by 436% for residential timers and 225% for commercial timers. Over the same time period, 400 residential and 100 commercial post-installation inspections were performed, exceeding the goals by 540% and 217% respectively. Based on the results of an associated impact evaluation, the water savings under this program is estimated at 59 gallons per day per residential site and 320 gallons per day per commercial site, or 783 acre-feet per year of overall savings.
- Rancho California Water District Residential Irrigation Efficiency Implementation Program and Enhanced Agricultural Irrigation Efficiency Program (December 2014) - The Rancho California Water District conducted two programs within the City of Temecula, and in portions of the City of Murrieta and southwest Riverside County. The Residential program was designed to encourage 500 high water users to participate in a cost-effective program to reduce their water consumption. Despite limited participation (possibly due to the launch of the program during low water use months), those who participated in the program benefited from the onsite irrigation audits that allowed them to identify potential irrigation upgrades, which included upgrading of the irrigation controller to a Smart Weather Based unit, realignment of irrigation spray heads, and the replacement of more efficient nozzles. The Agricultural program expanded the assistance provided to local farmers through an existing ag efficiency program by installing weather stations and soil moisture sensors at avocado farms in the District's service area, providing the farmers with more data to help make more informed irrigation scheduling decisions..
- Municipal Water District of Orange County California Sprinkler Adjustment Notification System (December 2014) - The Municipal Water District of Orange County developed the California Sprinkler Adjustment Notification System (CSANS) allows property owners to turn their 'dumb' irrigation timers into smart timers at no cost. A system widget alllows customers to register to receive regular e-mails from their water provider containing the updated irrigation factor specific to the weather at their geographic locations. The factor is used to make global irrigation scheduling adjustments on irrigation timers that have a percent adjustment feature. In addition to the irrigation adjustment factor, water agencies can customize these emails to include agency-specific information, such as seasonally appropriate gardening suggestions, rebate program information, water supply updates, etc.
- West Basin Municipal Water District Water Efficient Equipment Installation Program(September 2014) - West Basin's Commercial, Industrial, Institutional (CII) Incentive Program implemented water efficiency measures within the CII sector, targeting businesses and institutions in the District's service area that have facilities with cooling towers or those industries using water for manufacturing of products and/or services (i.e., oil refining, mining and metal plating, processing/dying/laundering of textiles, food and beverage production). West Basin provided technical assistance to identify solutions to use water more efficiently. The project aims to conserve water and energy by retrofitting existing CII sites with more water and energy efficient equipmen to help West Basin’s water retailers meet the goals and objectives of the California Urban Water Conservation Council’s CII Best Management Practices.
- City of Corona Department of Water & Power Water Use Efficiency Master Plan Final Project Report (September 2014) - The City of Corona developed this Water Use Efficiency Master Plan to identify the largest water consumers in the City and create strategies to improve their efficiency. It identifies cost-effective and innovative capital improvement projects that would help conserve water including increasing reclaimed water use and groundwater recharge, and updating inefficient and outdated infrastructure. One of the most important objectives of the Project was to pave the way to identify and prioritize water conservation projects that, when implemented in full, would help the City achieve their 20% by 2020 State mandated target. This document will be used as a planning tool and illustrates that water conservation efforts by the City are a feasible and cost-effective means of assuring adequate future water supplies.
- Bureau of Reclamation The Influence of Conservation Pricing and Other Non-price Factors on Residential Water Demand (May 2014) - Water conservation, including conservation pricing, is a demand side approach to water management that can help avoid the costs associated with water supply expansion or can be implemented in areas that do not have a financially viable supply side option. This report evaluates the effectiveness of conservation pricing, specifically the use of an increasing block rate pricing structure, in reducing municipal and industrial water demand. Different types of increasing block rate structures would be expected to have varying levels of effectiveness in reducing water demand. This research evaluates the influence of various marginal water prices on the quantity of water demanded and the most appropriate rate structure for meeting water conservation goals.
- City of Anaheim Water Use Efficiency Master Planning Grant Report (April 2014) - Anaheim's Water Use Efficiency Master Plan builds upon existing water conservation program achievements to help reach the City's goal of a 20 percent reduction in urban per capita water use by 2020. The Master Plan identifies potential conservation program concepts for specific customer sectors (i.e. residential, commercial, industrial and landscape-irrigation) and recommends a viable program mix with several implementation options focusing on landscape efficiency and innovative water use efficiency projects. The estimated water savings is projected to be 23 gallons/capita/day once the Master Plan is implemented.
- Eastern Municipal Water District Perris Water Filtration Plant Reject Recovery Project (April 2014) - The Perris Water Filtration Plant routinely discharges a reject flow of 1.0 mgd at capacity. This reject flow is discharged to the sewer and processed at EMWD Perris Valley Regional Water Reclamation Facility. The new Reject Recovery Facility diverts the reject stream from the sewer and treats the flow using low pressure membrane filtration. At capacity, approximately 0.85 mgd is returned to the Filtration Plant and 0.15 mgd is discharged to the sewer, resulting in a decrease in imported raw water and reduced flows to the wastewater treatment plant. This also results in substantial operations, maintenance, and energy savings.
- Metropolitan Water District of Southern California Conservation Market Study Final Project Report (March 2014) - Under this project, The Metropolitan Water District of Southern California’s water conservation programs were reviewed. The Large Landscape Saturation Survey collected Geographic Information System (GIS) data on the location of past conservation programs, large landscapes, and recycled water systems. Results from the saturation survey will be used to guide future conservation programs at Metropolitan. The second project is a Multiple Strategy Document that reviews conservation strategies utilized within Metropolitan’s service area. (Both documents are included as appendices to this report.)
- Metropolitan Water District of Southern California Landscape Water Use Efficiency Research Project (October 2013) - Under this project, The Metropolitan Water District of Southern California conducted water savings analysis for smart controllers that have been installed for more than four years using regional data, and identified water savings opportunities by surveying conditions for landscape water use behaviors and use of irrigation devices within Metropolitan’s service area.
- Metropolitan Water District of Southern California Friendly Turf Replacement Incentive Program (September 2013) - This project transformed more than 2 million square-feet of irrigated turf to California Friendly landscapes with climate-appropriate plants, efficient irrigation, permeable surfaces to allow rainwater infiltration, and mulch to preserve soil moisture. These lands have included residential and commercial projects throughout The Metropolitan's Water District of Southern California's 5,200 square-mile service area.
