As part of its Capital Improvement Program, DC Water is replacing existing 12-inch and smaller cast iron water mains in various locations throughout the city. Construction for this project will occur in the Capitol Hill neighborhood (see construction location map on the back). These efforts will help improve water quality and system reliability, increase water pressure in some areas, and maintain adequate flows throughout the system.


scope of work

  • Installation of approximately 6,316 linear feet of 4-inch up to 12-inch water mains
  • Replacement of service lines – including free private side replacement of lead and galvanized iron pipe
  • Replacement of fire hydrants and valves
  • Restoration of all surfaces disturbed by the project construction upon completion of work



  • Construction start: On or about 02/06/2023
  • Construction completion: On or about 03/15/2024
  • Normal work hours: 9:30 AM to 3:30 PM, Monday through Friday


The contractor may, at times, need to work at night or on weekends, dependent upon certain construction activities or due to inclement weather.


important information

  • For all planned temporary water service shut-offs, affected residents will be notified 48 hours in advance. Service interruptions should be minimal.
  • Construction activities such as these may cause temporary discolored water or low water pressure. If you experience discolored water, it is recommended that you flush your cold water tap from the lowest point inside your property for approximately 15 minutes. If your water does not clear after this process, please contact DC Water’s Water Quality and Technology Division, or our 24-hr Emergency/Command Center.



  • Flagging operations and lane closures may be required daily for each construction phase to maintain traffic in the construction work zone. All Traffic Control Plans will be approved by the District Department of Transportation (DDOT).
  •     At various times during construction, “No Parking” signs may be placed in certain areas in and around the work zone.  Notifications regarding “No Parking” zones will be posted 72 hours prior to construction, as required by DDOT.



DC Water is currently working closely with DDOT to ensure minimal traffic disruptions during this project. Regular updates will also be provided to impacted residents, Advisory Neighborhood Commission 6B, Ward 6 representatives in the Mayor’s Office of Community Relations and Services, and Ward 6 Councilmember Chales Allen and members of his staff.
