PAWSD is accepting proposals for the design to replace the existing Lift Station 7, the gravity sewer main connecting Lift Station 7 to Lift Station 6 and the sealing of the Lift Station 7 wet well and all overflow tanks at Lift Stations 7 and 6. The project is intended to replace the existing aging infrastructure and reduce infiltration from the leaking sewer main and provide additional protections against Sanitary Sewer Overflow (SSO) events. The Scope of Work includes the design of a replacement lift station and associated improvements including but not limited to gravity and force sewer main connections, installation of a valve vault and site improvements. Electrical upgrades and replacement of 8 gravity sewer. Communication and controls will be designed by PAWSD staff but must be coordinated with the Design Engineer. PAWSD is in the process of converting multiple lift stations from vacuum-primed pumps to submersible pumps. The design shall be coordinated with the Districts standardization efforts, including but not limited to, pumps, electrical equipment, communications, instrumentation and controls. The new lift station design shall incorporate the exiting emergency overflow vaults. Design services shall include a project phasing plan for maintaining sanitary sewer flows during construction and start-up of the new lift station and replacement of the sewer main as well as demolition and removal of unused equipment and materials associated with the existing lift station.
