Clean Water Construction Grant Program - Stormwater Grey Infrastructure Projects

<< Back to Clean Water Construction Grant Program main page

Stormwater Grey Infrastructure Projects prevent or reduce discharge of stormwater pollution from industrial activities at municipal facilities into storm sewers, combined sewer systems, or District waterbodies. Industrial activities include those for which stormwater pollution prevention is required under the Multi-Sector General Permit (MSGP) permit, the District’s Municipal Separate Storm Sewer (MS4) permit, or other National Pollutant Discharge Elimination System (NPDES) permits.

Project examples

• Leachate pretreatment at municipal landfills and trash transfer stations;
• Infrastructure to prevent stormwater from coming into contact with contaminants; and
• Any method, conveyance, equipment, or infrastructure used as part of a system for treating stormwater to remove pollutants.

• Project site is publicly owned and located in the District of Columbia;

• Project contributes to achievement, maintenance, or compliance with the enforceable requirements of the CWA;
• Project must include construction; however, funds can also be used for design;
• Application includes a feasible plan for maintenance of the structure, restoration, or planting that ensures continuing functionality;
• Application must present a project that can be completed within three-years. Alternatively, the project can be broken into design and construction phases that are funded consecutively, with each being completed within a three-year time period;
• Projects must be voluntary, and as such, cannot be used to meet the stormwater management requirements of 21 DCMR Chapter 5; and
