Local Advanced Water Purification System (Local AWPS)

Description of Project: The Local AWPS project consists of two Phases. This IFB is for Phase 1 that will produce 1.125 MGD of reverse osmosis permeate and will include housekeeping pads for future skids and pipe headers sized enough to accommodate expansion. Phase I Motor Control Centers will also accommodate for Phase II electrical loads. The permeate produced from the project will be blended with the existing tertiary-treated recycled water to achieve an instantaneous TDS concentration of 400 to 500 mg/L. The Local AWPS will be constructed without interruption to the current treatment operations, except as allowed under special circumstances, such as piping and utility tie-ins. The electrical service, potable water service and fire water supply will be independent from the RWQCP's service. New service connections will be made with City of Palo Alto Utilities (CPAU). The Project will construct a new odor control structure, membrane filtration, reverse osmosis system, a new permeate storage tank, blending station, new chemical storage facilities, electrical, instrumentation and control systems. Site work includes pile foundation, concrete slab, yard piping, replacement of a sewer line, paving, grading, landscaping, a metal canopy, a pre-engineered electrical building and a perimeter wall. THE ENGINEER'S ESTIMATE FOR THIS PROJECT IS: $53,598,743
