Potomac WFP Water Quality/PFAS Pilot Project

The Washington Suburban Sanitary Commission of Maryland is soliciting sealed responses for a progressive design-build contract to design, construct, and operate a PFAS pilot plant at the Potomac Water Filtration Plant. The project aims to evaluate treatment trains to address water quality concerns, including per- and polyfluoroalkyl substances, disinfection by-products, and other contaminants. The work is divided into a preliminary stage, covering design up to 70 percent and early procurement, and a completion stage encompassing final design, construction, commissioning, and a minimum of 12 months of operational data collection. Proposals must be submitted via the WSSC eProcurement Portal by December 1, 2026. Award decisions will be based on the most advantageous proposal, evaluated on project approach (30 percent), key team member experience (30 percent), technical experience (20 percent), and progressive design-build team experience (15 percent), with price not being the sole determining factor. Required submissions include a technical proposal without cost, various affidavits regarding conflicts of interest and Iran investment activity, and a statement of offeror qualifications. The contract requires strict adherence to Maryland's prevailing wage statutes and the Maryland Buy American Steel Act. Selected design-builders must provide performance and payment bonds equal to the completion stage price, as well as a one-year maintenance bond. Additionally, the project emphasizes supplier diversity, recognizing certified Minority Business Enterprises and Small Local Business Enterprises. All materials and equipment must be stored and maintained according to manufacturer and owner specifications until the project is accepted as substantially complete.
