Section 2 Water Demand with purchased imported water, storm water, and recycled water. OCWD further protects the groundwater basin from seawater intrusion through the injection of imported and recycled water along the coast, known as the Talbert Injection Barrier. Since demands for replenishment for groundwater basin storage and seawater barriers are driven by the availability of supply to the groundwater basin in Orange County, the demand forecast for this type of use is based on the projection of the following supplies under normal conditions: • Santa Ana River Flows; • Incidental Recharge; • Replenishment (surplus) supplies from Metropolitan; and • Recycled Supplies for replenishment use. Table 2-5 shows the historical amount used for indirect consumption in MWDOC’s service area. Table 2-5: Historical Water Demands for Indirect Water Use in MWDOC’s Service Area (AFY) Fiscal Year Ending 1990 1995 2000 2005 Total Demand 168,000 193,000 228,000 161,000 2.4. SBx7-7 Requirements 2.4.1. Overview SBx7-7, The Water Conservation Act of 2009, was signed into law on February 3, 2010, as part of a comprehensive water legislation package. As discussed above, the bill sets a goal of achieving a 20% statewide reduction in urban per capita water use, and directs urban retail water suppliers to develop targets to meet a 20% reduction in per capita water use by 2020, and an interim 10% reduction by 2015. Water suppliers receive partial credit for past efforts in conservation and deductions for direct and indirect use of recycled water. As a result not all agencies need to reduce demand by 20% in order to comply with the legislation. A retail agency that does not comply with the requirements of SBx7-7 will not be eligible for water related grants or loans from the state on and after July 16, 2016. However, if an agency is not in compliance documents a plan and obtain funding approval to come into compliance they could become eligible for grants or loans. As a wholesale water supplier, MWDOC is not required to establish and meet targets on its own. MWDOC’s role implementing the legislation is to assist each retail water supplier in Orange County in analyzing the requirements and establishing their baseline and target water use, as guided by DWR under the Methodologies for Calculating Municipal Water District of Orange County 2010 Regional Urban Water Management Plan Final 2-7
Section 2 Water Demand Baseline and Compliance Urban Per Capita Water Use (Technical Methodologies), dated February 2011. This section includes a description of the efforts by MWDOC to assist retail agencies in complying with the requirements of SBx7-7, including the formation of a Regional Alliance to provide additional flexibility to all water suppliers in Orange County in meeting compliance under the legislation. This section also includes the documentation for calculations that will allow retail water suppliers to use recycled water for groundwater recharge (indirect reuse) to offset a portion of their potable demand when meeting the regional as well as individual water use targets for compliance purposes. MWDOC is also required to include in its RUWMP a discussion of programs intended to be implemented to support retail agencies in achieving their per capita water reduction goals. This is covered in Section 4 – Demand Management Measures. 2.4.2. Orange County 20x2020 Regional Alliance MWDOC in collaboration with all of its retail agencies as well as the cities of Anaheim, Fullerton, and Santa Ana, has created the Orange County 20x2020 Regional Alliance in an effort to create flexibility in meeting the per capita water use reduction targets required under SBx7-7. This Regional Alliance will allow all of Orange County to benefit from regional investments such as the GWRS, recycled water, and water use efficiency. The members of the Orange County 20x2020 Regional Alliance are shown below in Table 2-6.
