Document Description
Note: Addendum No. 1 The proposed Highway 86 Domestic Water Transmission Main Phase 2 project will supply the communities of Salton Sea Beach, Desert Shores, and Salton City with domestic water from a more reliable groundwater source located ~16 miles to the north in the Thermal area. This project will consolidate the Coachella Valley Water District (CVWD) Improvement District No. 11 public water system with CVWD's Thermal public water system. The proposed route of the pipeline parallels Highway 86 in the west shoulder within the existing highway righ-of-way and will be installed within private property until Avenue 86. The CVWD is in the process of obtaining a 20 ft strip easement for the pipeline from property owners aouth of Avenue 81. The 30 inch diameter pipe will connect to an existing 30 inch diameter line located on the west side of Highway 86 at Avenue 74. From Avenue 74 south to Avenue 81, the pipe will be aligned ~110 ft from the centerline (10 ft from the edge of the existing highway ROW). The pipeline follows this alignment from Avenue 81 south to Avenue 86, for a total distance of ~7 miles. At Avenue 86, the pipeline connects to an existing 16 inch diameter pipe that currently supplies CVWD Improvement District No. 11 with groundwater from a small well field located near Avenue 86. The pipeline will be installed with a minimum of 3 ft of earth cover. Vertical deflections and restrained koints will be installed where the proposed pipe crosses other utilities including irrigation mains, agricultural drain lines, storm drain culverts, and buried telephone lines. In-line valves will be installed at half mile intervals and crosses for future connections will be installed at ~6 locations. The pipeline will be placed in polyethylene wrap to protect the pipe from mildy corrosive soils. The primary purpose of this project is to provide reliable domestic water supplies to communities in CVWD's Imperial County service area, including Salton Sea Beach, Desert Shores, and Salton City.
