DC Water's Clean Rivers Project is a $2.7 billion program to reduce combined sewer overflows into the Anacostia and Potomac Rivers and Rock Creek.

Working with design-builder Anchor Construction and in joint venture with Nitsch Engineering, AKRF led the design and maintenance of 79 green infrastructure facilities to manage stormwater runoff from 15.6 impervious acres and 29.4 acres of total contributing drainage area.

Green infrastructure practices include rain gardens in planter strips and curb extensions, permeable pavement on streets and alleys, and downspout disconnection, including rain barrels. In 2021, DC Water announced the design-build delivery of green infrastructure practices reduced stormwater runoff into Rock Creek by nearly 20 percent.
