Technical Reports and Resources
The following publications provide information that may be helpful for Southern California agencies and businesses in implementing water conservation practices:
- Smart Irrigation Timer Rebate Program Evaluation (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.
- 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..
- 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 Metropolitan 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.
- 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.
- 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.
