Wastewater Engineering Services

The Washington Suburban Sanitary Commission (WSSC) is soliciting proposals under solicitation number 86593 for comprehensive wastewater engineering services to be performed throughout WSSC’s Sanitary Sewer District in Maryland. The scope includes a broad range of services aimed at supporting WSSC’s compliance with regulatory mandates and improving sewer system performance, including sewer basin assessments, preventive maintenance program optimization, blockage analysis, and condition inspections utilizing CCTV, smoke testing, and flow monitoring. Work must comply with WSSC’s internal standards, certifications such as NASsCO PACP and MACP, and reporting formats. The contract features a three-year base period with an optional two-year extension, requires firm fixed labor rates for the base term, and carries detailed insurance, bonding, and subcontractor requirements. The delivery location is the WSSC service area near Laurel, Maryland, and all work must be coordinated under WSSC direction with adherence to contract requirements for inspections and technical reporting. Proposals must be submitted electronically through WSSC’s eProcurement Portal by January 14, 2026, with no late submissions accepted. The evaluation will follow a best-value trade-off methodology where technical factors—weighted heavily on project approach (35%), key personnel qualifications (30%), and firm experience (20%)—are considered alongside pricing (15%). Offerors are required to submit detailed representations and certifications, including conflict of interest affidavits and insurance confirmations. Key personnel must have relevant experience especially in permitting with federal, state, and local agencies and remain assigned throughout the contract period. The contract also includes stringent compliance requirements related to minority and small business participation, requiring offerors to submit certification forms and adhere to reporting and waiver documentation processes overseen by WSSC’s Office of Supplier Diversity and Inclusion. Security clearances are mandatory for personnel requiring access to certain project plans, and contractual performance will be subject to WSSC’s inspection and acceptance processes.
