All residents, private companies and government agencies must obtain approval from DC Water prior to performing any work that directly or indirectly affects the public water and/or sewerage systems. The Permit Operations Department is the starting point for all of DC Water's permit services. Permit Operations can provide you with mapping of the existing water and sewer infrastructure and can answer many of your questions. If you have general permitting questions please call 202-646-8600.

If your project is more complex, then your plan will need to be reviewed and approved by the Department of Engineering and Technical Services to verify your design is in conformance with DC Water Standards. If you have questions about larger more complex projects please call 202-646-8600.
