2015 URBAN WATER MANAGEMENT PLAN 1 INTRODUCTION Water Code Sections 10610 through 10656 of the Urban Water Management Planning Act (Act) require every urban water supplier providing water for municipal purposes to more than 3,000 customers or supplying more than 3,000 acre -feet (AF) of water annually to prepare, adopt, and file an Urban Water Management Plan (UWMP) with the California Department of Water Resources (DWR) every five years in the years ending in zero and five. The 2015 UWMP updates are due to DWR by July 1, 2016. This 2015 UWMP provides a detailed summary of present and future water resources and demands and provides an assessment of the City of Santa Ana's (City) water resource needs. Specifically, the UWMP provides water supply planning for a 25 -year planning period in five -year increments and identifies water supplies needed to meet existing and future demands. The demand analysis must identify supply reliability under three hydrologic conditions: a normal year, a single -dry year, and multiple -dry years. The City's 2015 UWMP updates the 2010 UWMP in compliance with the requirements of the Act as amended in 2009, and includes a discussion of: • Water Service Area and Facilities • Water Sources and Supplies • Water Use by Customer Type • Demand Management Measures' • Water Supply Reliability • Planned Water Supply Projects and Programs • Water Shortage Contingency Plan f Recycled Water Use Since the original Act's passage in 1983, several amendments have been added. The most recent changes affecting the 2015 UWMP include Senate Bill 7 as part of the Seventh Extraordinary Session (SBx7 -7) and SB 1087. SBx7 -7, or the Water Conservation Act of 2009, is part of the Delta Action Plan that stemmed from the Governor's goal to achieve a 20 percent statewide reduction in urban per capita water use by 2020 (20x2020). Reduction in water use is an important part of this plan that aims to sustainably manage the Bay Delta and reduce conflicts between environmental conservation and water supply; it is detailed in Section 3.2.2. SBx7 -7 requires each urban retail water supplier to develop urban water use targets to achieve the 20x2020 goal and the interim ten percent goal by 2015. Each urban retail water supplier must include in its 2015 UWMPs the following information from its target- setting process: • Baseline daily per capita water use • 2020 Urban water use target i 2015 Interim water use target compliance 75E -13 arcadis.com 1 -1
