This week in… Water Use Data

Last week, the State Water Resources Control Board released a database  describing residential water use in more than 400 water agencies in the state. The State Board reported that 87% of utilities surveyed are implementing mandatory restrictions on residential water use. Statewide, utilities reported a 10% savings in September 2014 compared to 2013. The San Francisco Bay, Sacramento River, and Central Coast all reduced daily per capita residential water use by more than 15% between September 2013 and 2014.

In other news…

  • The California Department of Water Resources has awarded $220 million in grants to 27 proposals to help California communities provide immediate drought relief and prepare for future droughts.
  • The Friant Water Authority and most of its member agencies have filed a petition for writ of mandate in Fresno County Superior Court, seeking a judicial review of the State Board’s actions this spring and summer that reduced allocations to junior water rights holders to zero.
  • Later this week, the Cambria Community Services District will open a new brackish water desalination plant on the San Simeon Creek that could produce up to 250 acre-feet per year. The plant was approved through an emergency permit and would only operate under State 3 drought conditions.
