Document Description
Coachella Valley Water District's (CVWD) Irrigation Lateral 119.64-7.5 is an old large-diameter concrete irrigation pipeline that delivers water from the Coachella Canal to farmers. The 3.5-milelong pipeline is part of a gravity-fed system interspersed with above-ground baffle stands roughly every quarter mile where the farmers' sub-laterals connect. The aging gravity system is leaking water from the pipeline joints, surging water out of the baffle stands, and spilling excess water at the tail end to the drain. This project would remove and replace approximately 8,800 linear feet of existing concrete pipe with new polyvinyl chloride (PVC) pipe. Additionally, the project would install a new master meter with isolation valves, a regulatory meter, a regulatory baffle stand, and five meters. The proposed improvements also include the removal of existing baffle stands east of Meter No. 1898. A trenchless utility installation method (Jack and Bore method) would be required to complete the work. Street improvements would also be required. The objective of these improvements is to increase operational efficiency, enhance water conservation, and improve customer service. Surrounding land uses consist of residential, agricultural, open space, and roadways. The project is not located within or adjacent to a conservation area associated with the Coachella Valley Multiple Species Habitat Conservation Plan. Ground disturbance and construction activities would occur within pre-disturbed soils.
