This project will renew and install hydraulic, energy efficiency, and operational improvements at each pump station. Work at the HSPS includes replacing the existing surge tank system with a new bladder type surge vessel of 30,000 gallons to protect the HSPS from potential damage by surge flows, rehabilitation of motors and control valves, installing new valves; and removing failed coatings and re-painting all exposed discharge piping. Work at the LSPS includes installing structural steel reinforcement between two existing concrete beams supporting Pump No. 2, removing existing anti-vortex plates and installing vortex suppression baskets on all six vertical turbine discharge pumps, and replacing all eleven existing wet well sluice gates with new gates. Item 6 Water & Wastewater Commission: July 16, 2025 Council: July 24, 2025 This item includes six allowances: • The allowance of $210,000 for replacing a large diameter gate valve at the HSPS. • The allowance of $210,000 for replacing a large diameter gate valve at the HSPS. • The allowance of $210,000 for replacing a large diameter gate valve at the HSPS. • The allowance of $760,000 for rehabilitating four pump motors at the HSPS. • The allowance of $110,000 for needed miscellaneous Supervisory Control and Data Acquisition equipment due to electrical and instrumentation and controls issues that could not be identified or foreseen during design. • The allowance of $500,000 for installing on-site parking.
