DC Water's
Projects

Our capital improvement plan is measured in the billions. That's the level of investment required to upgrade our water and sewer systems, comply with federal mandates to reduce nutrient discharges and combined sewer overflows to local rivers, and improve the efficiency of our operations. This work is occurring across the city, and using the search filters below you can see what's happening in your neighborhood.
