California American Water Implements Stage 3 Drought Contingency Plans in Ventura County

On April 1st, 2015 Governor Jerry Brown imposed mandatory 25% statewide water reduction from 2013 and prohibited water uses.  

But this 25% wasn't imposed across the board. The State Water Resources Control Board imposed cutbacks ranging from 4  to 36% from 2013 water use, applying higher guidelines to communities with higher consumption..

California American Water received a target reduction of 32% for its Ventura County customers, near the top of the state's guidelines. From June through August, a cumulative reduction of 27.2% was met, nearly 5% lower than the target. Cal Am customers in the Conejo Valley include most folks west of Moorpark Road.  Most other residents are served by the City of Thousand Oaks and California Water Service. 

As a result, Cal Am's Ventura County customers have been moved from Stage 2 to Stage 3 water-use restrictions. Effective immediately, water use by Cal Am customers in Ventura County is limited to one day a week - odd numbered addresses on Saturdays and even numbered addresses on Sundays  - no more than 15 minutes per station, between the hours of 5 p.m. and 9 a.m. Exemptions made for hand-watering, drip and microspray irrigation.

Additionally, a "drought surcharge" has been implemented. Customers who use more than 8,976 gallons of water per month will pay an extra 21 cents for every 100 gallons used.

These rules apply only to Cal Am customers. City of Thousand Oaks and Cal Water customer are not impacted at this point.
