About this file
This is a standard details reference document for the Washington Suburban Sanitary Commission (WSSC) in Maryland, serving as a comprehensive table of contents and design specification guide for miscellaneous construction details used in water and sewer infrastructure projects. The document, dated September 2021, catalogues 41 standard detail specifications organized by designation number (M/3.0 through M/22.1) and covers a broad range of construction elements including trench designs for rigid and flexible pipes of various materials, pipeline crossing details, concrete encasement and cradle specifications, tunneling and bore-and-jack installation procedures, access structures, safety equipment, and site management features. These standardized details are applicable to the Area Water and Sewer House Connection project, which involves constructing approximately 11,000 linear feet of water house connections (1 inch through 2 inch), approximately 2,600 linear feet of sewer house connections (4 inch through 6 inch), and approximately 335 linear feet of pressure sewer house connections across approximately 150 new service installations at various locations in Prince George's and Montgomery Counties, Maryland on an annual basis, with sealed responses due via WSSC's eProcurement Portal by 2:00 p.m. on Tuesday, May 26, 2026.
The document serves as a technical reference guide establishing uniform construction standards and methodologies for WSSC infrastructure projects rather than containing pricing terms, set-asides, incumbent information, or funding requirements. Contractors responding to the solicitation are expected to adhere to these standard details when designing and executing the water and sewer house connection installations, ensuring consistency and compliance with WSSC specifications across all project locations and service types.
