Santa Ana 2020 Urban Water Management Plan <br />arcadis.com <br />5-13 <br />5 CONSERVATION TARGET COMPLIANCE <br />The Water Conservation Act of 2009, also known as SBx7-7 (Senate Bill 7 as part of the Seventh <br />Extraordinary Session), signed into law on February 3, 2010, requires the State of California to reduce <br />urban water use by 20% by the year 2020 (20x2020). To achieve this each retail urban water supplier <br />must determine baseline water use during their baseline period and target water use for the years <br />2015 and 2020 to meet the state’s water reduction goal. Retail water suppliers are required to comply <br />with SBx7-7 individually or as a region in collaboration with other retail water suppliers, or demonstrate <br />they have a plan or have secured funding to be in compliance, in order to be eligible for water related <br />state grants and loans on or after July 16, 2016. <br />The City’s actual 2020 water use is lower than its 2020 water use target, therefore, demonstrating <br />compliance with SBx7-7. In its 2015 UWMP, the City revised its baseline per capita water use calculations <br />using 2010 U.S. Census data. Changes in the baseline calculations resulted in updated per capita water <br />use targets. <br />The following sections describe the efforts by the City to comply with the requirements of SBx7-7 and <br />efforts by MWDOC to assist retail agencies, including the formation of a Regional Alliance to provide <br />additional flexibility to all water suppliers in Orange County. A discussion of programs implemented to <br />support retail agencies in achieving their per capita water reduction goals is covered in Section 8 – <br />Demand Management Measures of this UWMP. <br />Complimentary to information presented in this section are SBx7-7 Verification and Compliance Forms, a <br />set of standardized tables required by DWR to demonstrate compliance with the Water Conservation Act <br />in this 2020 UWMP (Appendix D) including calculations of recycled water used for groundwater recharge <br />(indirect reuse) to offset a portion of the agency’s potable demand when meeting the regional as well as <br />individual water use targets. <br />Baseline Water Use <br />The baseline water use is the City’s gross water use divided by its service area population, reported in <br />GPCD. Gross water use is a measure of water that enters the distribution system of the supplier over a <br />12-month period with certain allowable exclusions. These exclusions are: <br /> Recycled water delivered within the service area <br /> Indirect recycled water <br /> Water placed in long term storage <br /> Water conveyed to another urban supplier <br /> Water delivered for agricultural use <br /> Process water <br />Water suppliers within the OCWD Groundwater Basin, including the City, have the option of choosing to <br />deduct recycled water used for indirect potable reuse (IPR) from their gross water use to account for the
