Potomac WFP Water Quality/PFAS Pilot Project

Washington Suburban Sanitary Commission (WSSC) is soliciting sealed responses for progressive design-build services on the Potomac WFP Water Quality/PFAS Pilot Project, with responses due August 20, 2026.

The scope encompasses design, construction, and operation of a PFAS pilot treatment plant at the Potomac Water Filtration Plant facility in Montgomery County, Maryland. The contractor will perform comprehensive engineering design, permitting, construction management, and operational support for pilot-scale treatment systems addressing per- and polyfluoroalkyl substances contamination in the water supply. Responsibilities include regulatory coordination, environmental compliance, performance monitoring, data analysis, and detailed reporting throughout the pilot operation period. The project is structured to permit phased implementation with design refinement opportunities based on pilot results prior to full-scale deployment decisions.

The engagement supports both technical innovation and risk mitigation by testing treatment approaches at controlled scale before significant capital investment in full-scale infrastructure. No specific contract value, contract term, or incumbent information is disclosed in the solicitation documents. A detailed Scope of Work document (828167plantwssc.pdf) is attached and available for review.
