The District was formed with the primary mission of conserving groundwater through the use of surface water diverted from the Santa Clara River by United Water Conservation District and Conejo Creek as secondary water supplies to supplement irrigation wells.

Later the District drilled and equipped eleven deep wells to supplement both the surface water supply and the farmers’ wells during drought or dry seasons. These wells in conjunction with the pipeline system and available surface water aid in conserving groundwater and power through more efficient distribution.
