Cross-Connection

Cross-Connection Control Program

The DC Water Cross-Connection Control Program is responsible for inspection, regulation, enforcement and education in preventing backflow incidents in the District. A cross connection is a physical connection between the drinking water system and a non-potable source. Backflow occurs when an unprotected cross-connection allows the reverse flow of a non-potable substance into the water system, potentially contaminating or polluting the drinking water supply. The Cross Connection Control Program ensures proper backflow protection methods are used at cross-connections in the District to prevent contamination and protect public health.

For additional information about the Cross-Connection Control Program, contact the Drinking Water Division at 202-364-3144 or email . Learn more about ensuring water quality in commercial buildings.
