About Water Use Efficiency
- Provides expertise to local agencies and individuals regarding agricultural and urban water and energy conservation, reclamation and reuse of water, land and water use, and drainage management.
- Manages the California Irrigation Management Information System (CIMIS), which collects data from over 140 automated weather stations throughout the State. CIMIS provides reference evapotranspiration (ETo) and weather data to the public for irrigation scheduling and other purposes such as water balance analyses, pest management, energy generation, fire fighting, weather forecasting, and scientific research.
- Assists in establishing mobile laboratories that conduct irrigation system evaluations.
- Carries out data analysis, demonstration projects, and research to achieve energy and water use efficiency.
- Provides loans and grants to make more efficient use of water and energy resources.
- Local urban water suppliers and municipalities are called upon to implement their local water shortage contingency plans immediately in order to avoid or forestall outright restrictions that could become necessary later in the drought season. Local water agencies should also update their legally required urban and agricultural water management plans, which help plan for extended drought conditions. The Department of Water Resources will make the status of these updates publicly available.
- Agricultural water suppliers must prepare and adopt an Agricultural Water Management Plan (AWMP) no later than December 31, 2012, update it on December 31, 2015, and on or before December 31 every five years thereafter. Agricultural water suppliers that supply water to more than 25,000 irrigated acres, less supplied recycled water, are required to submit AWMP’s. AWMP contents are outlined in Section 10826 of the Water Code. Agricultural water suppliers also are required by the Water Code §10608.48(d) to report on EWMPs that have been implemented and those that are planned to be implemented, an estimate of efficiency improvements achieved, and efficiency improvements expected in the next five and ten years and report to the Department of Water Resources. As of January 29, 2014, 29 plans were received of the estimated 55 water agencies required to submit representing 53 percent compliancy. Another 12 suppliers voluntarily submitted AWMP’s. The results are outlined in the table and maps below.

- The 2010 UWMPs must be adopted by July 1, 2011 and submitted to DWR by August 1, 2011. Usually, UWMPs are due on December 31 of years ending in 0 and 5, but a 6-month extension has been granted for submittal of the 2010 UWMPs to provide additional time for water suppliers to address the SB X7-7 requirements(Division 6 Part 2.6 of the Water Code §10610 - 10656). Every urban water supplier that either provides over 3,000 acre-feet of water annually or serves more than 3,000 connections is required to assess the reliability of its water sources over a 20-year planning horizon considering normal, dry, and multiple dry years. This assessment is to be included in its UWMP, which is to be prepared every 5 years and submitted to the Department of Water Resources. As of February 1, 2014, 396 water agencies submitted plans of the 440 required to submit plans representing 90 percent compliancy. The results are outlined in the map below and a table detailing specific agency results.

- The Independent Technical Panel (ITP) The California Department of Water Resources is hosting a webinar meeting of the Independent Technical Panel (ITP) on Demand Management Measures (DMMs) Urban Water Management Plan (UWMPs) Demand Management Measure Reporting and Requirements. The webinar is on Tuesday March 11, 2014 from 10:00AM-12:00PM at the Bonderson Building, Room 301, 3rd Floor 901 P St., Sacramento, CA 95814. The meeting agenda and other materials may be found on this webpage: http://www.water.ca.gov/calendar/index.cfm.
- California Water Code §10631.7 directs DWR to convene the ITP once every five years to provide information and recommendations to DWR and the Legislature on new DMMs, technologies, and approaches.
- The ITP elected to submit two legislative reports. A first report which would include only recommendations related to UWMPs and would be submitted in time for consideration during the 2014 Legislative Session. The second report to the Legislature would consist of recommendations on other DMMs not related to the UWMPs.
