Polymer Injection System Project

The Polymer Injection System Project, solicitation number 46t191, is a construction project for the City of San Mateo Wastewater Treatment Plant designed to improve sludge handling reliability and reduce pump operating pressures. The scope of work includes the installation of two new polymer pumps on concrete pads, the construction of two new polymer injection rings, and all associated piping, valves, electrical, and instrumentation work, including a new local control panel. The project requires the contractor to coordinate closely with a separately retained System Integrator to ensure seamless communication and control integration with existing plant systems. Key deliverables include hardware equipment submittals, project-wide loop drawings, control panel engineering, a final technical manual, and the successful completion of a thirty-day performance test. The estimated construction cost is $297,051, and the contract period is set for 120 working days. Bids must be submitted in a sealed format by October 8, 2026, at 2:00 p.m. The contract will be awarded to the lowest responsive and responsible bidder. Bidders are required to provide a bid security equal to 10% of the maximum bid amount, and the successful bidder must furnish performance and payment bonds for 100% of the contract price. The project is subject to prevailing wage requirements and must comply with the California Building Code, the Americans with Disabilities Act, and various environmental and safety regulations, including the City's NPDES permit. All project data and document management will be handled through the ProCore platform. The contractor is also responsible for implementing water pollution and erosion controls and providing a comprehensive Quality Control Plan for review by the Engineer.
