The Santa Clarita Valley Water Agency (SCV Water) is a full-service regional water agency located in the Santa Clarita Valley. SCV Water provides water service to approximately 300,000 business and residential customers over an area of nearly 200 square miles. Half of the water provided comes from local groundwater, with the other half imported from the State Water Project and other sources. SCV Water was formed on January 1, 2018 and combines the former service areas of Castaic Lake Water Agency, Newhall County Water District, Santa Clarita Water Division and Valencia Water Company. Following a multi-year public engagement process, the agency was formed through Senate Bill 634 authored by Senator Scott Wilk and signed by Governor Jerry Brown on October 15, 2017. SCV Water was formed to enhance regional water management and reduce costs for local ratepayers.
