Title

Highway 86 Domestic Water Transmission Main

Description

The proposed Highway 86 Domestic Water Transmission Main project will supply the communities of Valerie Jean and Oasis with domestic water from a more reliable groundwater source located approx. 8 miles to the north of the Thermal area. The proposed route of the pipeline parallels Highway 86 in the west shoulder within the existing right-of-way (ROW). The 30 inch diameter pipeline will connect to an existing 18 inch diameter pipeline on the east side of Highway 86 at Avenue 58 and cross to the west side of Highway 86. From Avenue 58 south to Avenue 62, the pipeline will be aligned approx. 26 feet from the existing centerline within the highway ROW. Approaching Avenue 66, the proposed pipeline will be located 35 feet from the centerline (15 feet from the edge of asphalt and 15 feet from the ROW line).The pipeline follows this alignment from Avenue 66 south to Avenue 74, a distance of approx. 4 miles. The pipeline will be installed with a minimum of three feet of earth cover. Vertical deflections will be installed where the proposed pipeline crosses other utilities including irrigation mains, agricultural drain lines, storm drain culverts and buried telephone lines. In line valves will be installed at 0.5 mile intervals and crosses for future connections will be installed at approx. 8 locations. The pipeline will be replaced in polyethylene wrap to protect the pipe from mildly corrosive soils. The primary purpose of this project is to provide reliable domestic water supplies to communicate in CVWD's lower valley service area, including Valerie Jean and Oasis.
