Environmental Impact Bond

The results are in—green infrastructure projects achieved goals for stormwater runoff

DC Water announced the success of both its first green infrastructure (GI) projects in Rock Creek and the innovative Environmental Impact Bond (EIB) that financed them. The intent of the projects and robust evaluation of project outcomes was to establish the effectiveness of green infrastructure in the District and reduce combined sewer and stormwater runoff into Rock Creek, improving the health of waterways in the District.

DC Water Breaks Ground on Piney Branch Tunnel, Final Phase of DC Clean Rivers Project

Today, DC Water broke ground on the Piney Branch Tunnel, the final major tunnel in our Clean Rivers Project. This work will help keep sewage and trash out of local waterways and make Rock Creek, the Potomac River, and the Chesapeake Bay cleaner for our community.

When we finish the Piney Branch Tunnel, it will hold at least 4.2 million gallons of rainwater and wastewater during heavy storms. Instead of overflowing into Piney Branch, that water will go to the Blue Plains Water Resource Recovery Facility, where it will be treated.
