2025 URBAN WATER MANAGEMENT PLAN <br /> MAY 2026/FINAL DRAFT/CAROLLO <br /> CHAPTER CONSERVATION TARGET COMPLIANCE <br /> The Water Conservation Act of 2009, also known as Senate Bill (SB) X7-7, mandated a 20 percent <br /> reduction in urban per-capita water use across California by 2020.To achieve this goal, the Act required <br /> each retail water supplier to establish an urban water-use target, contributing to the State's collective <br /> efforts. The Legislature stated that the combined reductions from all retail suppliers would fulfill the <br /> statewide legislative mandate. <br /> The goal of this chapter is to allow the retail water supplier to report on their progress toward meeting <br /> their urban water-use targets in their Urban Water Management Plan (UWMP), pursuant to Water Code <br /> Section 10608.40. Suppliers that did not meet their 2020 target in 2020 are required to compare their <br /> 2025 water use to the 2020 target. As the City's actual 2020 water use was lower than its 2020 water use <br /> target, this did not apply to the City. <br /> Retail water suppliers are required to comply with SB X7-7 individually or as a region in collaboration with <br /> other retail water suppliers or demonstrate they have a plan or have secured funding to be in compliance, <br /> in order to be eligible for water related state grants and loans. <br /> When determining water use in an UWMP, two terms are often used interchangeably: <br /> ■ Daily Per Capita Water Use.The amount of water used per person per day. In the UWMP <br /> calculations, this is total water use within a service area, divided by population, and it is measured in <br /> gallons. <br /> ■ Gallons Per Capita Per Day(gpcd). This is the daily per capita water use measured in gallons. <br /> Therefore,the term commonly used when referring to "daily per capita water use" is "gallons per <br /> capita per day' or gpcd.' <br /> 5.1 Reporting Requirements <br /> MWDOC's Water Use Efficiency (WUE) programs helped Orange County meet the state's 20x2020 <br /> mandate by coordinating conservation efforts across its member agencies, funding and implementing <br /> regionally cost-effective efficiency programs, and enabling compliance through the Orange County <br /> 20x2020 Regional Alliance. By aligning its WUE portfolio directly with SB X7-7 requirements, supporting <br /> high-impact measures (especially outdoor water savings), documenting eligible indirect potable reuse <br /> credits, and centrally handling regional target calculations and reporting, MWDOC allowed participating <br /> retailers to comply collectively rather than individually resulting in regional per capita water use well <br /> below the required 2020 target. <br /> It is important to distinguish gpcd (as used in UWMPs) from the Residential Gallons Per Capita Per Day <br /> (R-GPCD) that is used in some reporting to the California State Water Resources Control Board (SWRCB). <br /> GPCD is the total water use from all sectors within a service area (residential, commercial, institutional, and <br /> any others) minus allowable exclusions (as defined in SB X7-7), then divided by the population.This is <br /> used in UWMPs. R-GPCD is only a part of the gpcd; it is the estimated residential water use in a service <br /> area divided by population. <br /> CITY OF SANTA ANA <br />
