San Jose Creek Water Reclamation Plant Stage III Primary Sedimentation System Expansion
MND - Mitigated Negative Declaration
The proposed project would include the following components: construction of two new Primary Sedimentation Tanks, extension of Channel 1 and Gallery 1, and repairs to the concrete and liner for Channel 2 and the Step Feed Channels at the SJCWRP. The proposed project would include construction of two new Primary Sedimentation Tanks (Tanks 6 and 7) along the southeast corner of the SJCWRP. The new Primary Sedimentation Tanks would be located south of the existing Primary Sedimentation Tanks and would be built to match the existing dimension and treatment capacity of the existing tanks. The Channel 1 and Gallery 1 structures are located near the inlet side of the existing Primary Sedimentation Tanks. The extensions would be constructed to match the existing design and would be approximately 42 feet long and 11 feet 10 inches wide. All corroded concrete and steel would be replaced at Channel 2 and the Step Feed Channels. Reinforcing steel that is corroded and has rust would be removed and replaced with new reinforcing steel. A bonding agent would be used to coat reinforcing steel and the surfaces of the existing concrete. The corroded channels would be restored to the original dimensions by installing concrete repair material. Damaged PVC liners would be removed and replaced. Operation of the project would require small mechanical equipment of approximately 5 horsepower and a chopper pump motor rated at 50 horsepower.
