STATE WATER PROJECT
The District’s annual importation of its State Water allocation (Table A water) is used to increase the recharge of groundwater basins in the District, beyond what water is naturally available within the Santa Clara River watershed.
This added recharge, paid through a voter-approved property tax special assessment, benefits all groundwater basins District-wide. UWCD also receives surplus State Water, known as Article 21 water, when it is available.
UWCD optimizes State Water deliveries by working with partners across the region to strategically transfer and exchange supplies for mutual benefit.

REGIONAL COLLABORATION:
STATE WATER INTERCONNECTION PROJECT
The proposed interconnection project will bring State Water allocations to western Ventura County. The project is a collaboration between the City of Ventura, Calleguas Municipal Water District, Casitas Municipal Water District and United Water Conservation District to enhance local and regional water security.
By partnering to bring State Water to multiple agencies throughout Ventura County, the project is economically advantageous and meets a regional water need.
Ventura has had a State Water entitlement since the 1970s but has been unable to use it because it lacked the facilities for conveyance. The interconnection would move up to 20,000 acre-feet of water per year through the Calleguas MWD system.
The project will include two turnouts for United, which will use the additional supply to manage the groundwater basins within its boundaries more efficiently.
