DC Water's

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.
