Westlands Water District (WWD) requests encroachment permission to assess potential damage to an existing concrete ground valve vault (vault), soil pipe, and ground valve in the Department of Water Resources right-of-way. Depending on the condition of these components, they may need to be repaired. The vault is an approximately 2-feet long by 2-feet wide by 2-feet deep prefabricated concrete box; the vault is buried and flush with the ground and allows aboveground access to an attached soil pipe, which is used for opening and closing the ground valve. The soil pipe is made of polyvinyl chloride and is approximately 6-inches in diameter and 8-feet long; it is the point of attachment between the vault and the buried ground valve. The ground valve is buried about 6 to 8 feet underground, is attached to existing pipes, and controls water flow.
WWD will assess the condition of the components after they locate them; to locate the components, WWD will excavate an area approximately 15-feet long by 15-feet wide by 8-feet deep. If repairs are necessary, WWD will replace the damaged components with new ones with similar dimensions and materials. Following the repairs, the excavation will be backfilled, compacted, and shaped to the original contours. Department of Water Resources will issue and encroachment permit for this work. WWD will benefit from this repair.
