Title
Walnut Grove Pump Station Abandonment Project
Description
The Central Valley Regional Water Board is issuing a 401 Water Quality Certification for the subject project. The project entails placing a 16-inch diameter gravity pipeline following the route of an existing 8-inch diameter forced main sewer line. The new pipeline will begin at Pump Station S064 and continue southeast parallel to ditch AGD1 for approximately 1,270 feet and cross a lateral agricultural ditch. The pipeline will then turn to the northeast for approximately 190 feet and cross a second lateral ditch, turn to the southeast again and travel approximately 500 feet along the adjacent agricultural land until reaching Pump Station S146. The gravity pipeline will outfall into the influent manhole at Pump Station S146. The total length of the new pipeline will be approximately 2,000 feet, with manholes place no more than 500 feet apart. The existing 8-inch force main will be abandoned in place.
