Green Infrastructure Projects at DC Water Facilities
As part of its Consent Decreet requirements, DC Water implemented Green Infrastructure (GI) at DC Water facilities to reduce the volume of stormwater entering the combined sewer system. The GI implemented under this project includes:
- Fort Reno Reservoir: 42,400 square feet of green roof and 8,400 square feet of pervious pavement
- Anacostia Water Pumping Station: 1,000 square feet of pervious pavement and 1,500 square feet of bioretention
- East Side Pumping Station: 6,600 square feet of green roof
These GI facilities were designed to capture precipitation from at least 90% of the storms in an average year. DC Water performs ongoing maintenance to ensure long-term performance of the facilities and pre/post-construction monitoring is providing data to improve future GI design, construction, operation and maintenance.
Construction of GI at DC Water Facilities was completed in accordance with the Consent Decree schedule. Ongoing regular maintenance activities began in January 2014 and continue today.
