Simi Valley

Overview

Golden State Water has proudly served Simi Valley since 1965, providing quality, reliable water to approximately 13,300 local customers.

Water delivered to customers in the Simi Valley System is treated surface water purchased from the Calleguas Municipal Water District, which obtains its supply from Metropolitan Water District of Southern California. The primary water supply is also supplemented with groundwater from the Simi Valley Groundwater Basin.

Drought

Golden State Water has activated its Staged Mandatory Water Conservation & Rationing (Schedule 14.1) filings which outline restrictions, water allocations, enforcement measures and surcharges designed to achieve reductions due to water supply shortages or to achieve identified water usage goals established by an authorized government agency or official. 

The Simi Valley community is in Stage 2. Under this stage, all outdoor irrigation is limited to two days per week. Outdoor irrigation is allowed only after 7PM and before 8AM, according to the schedule below.

Golden State Water customers who do not meet the Stage 2 mandatory 20% reduction in water use may be charged a drought surcharge of up to $2.50 per Ccf (or 748 gallons) for all usage in excess of the customer’s usage allocation. While Golden State Water is not currently implementing surcharges, we are closely monitoring water supply conditions and customer water usage and may implement surcharges if it becomes necessary to spur action and additional conservation.
