AI overview

The Washington Suburban Sanitary Commission (WSSC Water) is seeking qualified consultants to provide trunk sewer inspection services for its sanitary district in Montgomery and Prince George's Counties, Maryland. The work involves comprehensive inspection of trunk sewers 15 inches in diameter and larger, including associated manholes, located in wooded rights-of-way and along stream crossings. Services include project management; locating, opening, inspecting, and properly closing trunk sewer manholes; inspecting exposed pipes and stream crossings; documenting and dye testing all exposed sewers; and other source detection efforts. The consultant must also provide longitude and latitude coordinates for all manholes and exposed sewers, including those less than 15 inches in diameter. Work is generally clustered by basin across approximately 625 miles of trunk sewers, but the consultant must be prepared to complete work at any site within the bi-county area without additional compensation for scattered locations.

Key dates include a pre-proposal conference on July 30, 2026 at 2:00 PM (local time), a Q&A deadline on August 4, 2026 at 6:00 PM UTC, and a proposal submission deadline of August 20, 2026 at 2:00 PM local time. Proposals must be submitted via WSSC Water's eProcurement portal at https://procurement.opengov.com/portal/wsscwater. The contract is expected to be a multi-year Indefinite Delivery Indefinite Quantity (IDIQ) arrangement, with individual task orders issued for specific basin work.

Consultants must possess demonstrated experience in sanitary sewer inspection, including the ability to safely access manholes in remote and environmentally sensitive areas. The scope requires all engineering, labor, parts, materials, services, and equipment necessary to perform the inspections. No additional compensation will be provided for scattered job sites. The successful consultant will be expected to coordinate with WSSC Water's project managers and adhere to all safety and environmental regulations.

Evaluation criteria are detailed in the full RFP documents and will consider qualifications, experience, approach, and pricing. Minority Business Enterprise (MBE) and Small Local Business Enterprise (SLBE) participation goals apply. The contract is subject to WSSC Water's standard terms and conditions, including insurance and bonding requirements. All attachments, including the current contract report, goal setting worksheet, and special conditions, are available for download on the procurement portal.
