Urban Water Management Plan 2015

Division 6 in 1983, creating the UWMPA. Since this Assembly Bill, more than 20 amendments have changed the quantity of data required, as well as increasing the planning elements included in this 2015 plan. Early amendments to the UWMPA required 20 year planning horizons in 5 year increments for the comparison of water use to sources of water supply. More recently, these planning projections have been extended to 25 year planning horizons in order to maintain the 20 year projections, while the subsequent UWMP is completed. Additional amendments included requirements that water supplier’s UWMP provide provisions for a Water Shortage Contingency Plan, which would meet the specifications set forth in the UWMPA; demand management measures; and provisions for recycled water use. Recycled water use was added to reporting requirements due to its additional reliability for alternative water supply, and most notably, as an additional supply for future water use demand. Individual water purveyors, in coordination with other water purveyors in the same general area and to the extent practicable, must work to prepare the Water Shortage Contingency Plan. The individual water supplier must also describe the water demand management measures that are currently in practice, or those scheduled to be practiced. More than 15 amendments have been passed since the year 2000, amending the UWMPA and increasing reporting for the UWMP. Included in these amendments are SB 610 (Costa, 2001) and AB 901 (Daucher, 2001), which require urban water purveyors to review information regarding water to supply new large developments. Additionally, SB 318 (Alpert, 2004) requires the plan to review opportunities involved in the development of desalinated water, included but not limited to, ocean, brackish, and groundwater, as a long term supply. AB 105 (Wiggins, 2004) requires suppliers to submit their completed UWMP to the California State Library. SBX7-7 requires the state and its municipal water purveyors to achieve a 20 percent reduction in urban per capita water usage by the year 2020. The “20X2020” plan is intended to reduce water usage per capita by 10% by the year 2015, and 20% by the year 2020. The most recent of these amendments are: • AB2067 (2014), which requires urban water suppliers to address the nature and extent of the demand management measures implemented over the past 5 years, as well as document what measures are going to be implemented to meet the SBX7-7 targets. • SB1420 (2014) requires that plans be submitted electronically to the Department of Water Resources (DWR), and that the plan includes the standardized forms provided by DWR. Additionally, SB1420 requires that urban water suppliers quantify water losses in their reporting, and provides a mechanism to estimate future water savings from demand management measures. • SB1036 (2014) allows urban water suppliers to voluntarily report energy intensity related to water supplies.
