Small Diameter Water Main Replacement Project - Jackson and 12th Street, NE


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. These efforts will help improve water quality and system reliability, increase water pressure in some areas, and maintain adequate flows throughout the system. Construction for this project will occur on Jackson Street NE between 10th Street NE and 14th Street NE, and also on 12th Street NE from Kearny Street NE to Irving Street NE. 

Scope of work

  • Installation of  2,700 linear feet of 8-inch water mains
  • Replacement of service lines (lead and/or other) in public space, as needed
  • Replacement of fire hydrants and valves


  • Construction start: March 2016
  •  Construction completion: May 2017
  • Normal work hours: 9:30 am – 3:30pm, Monday through Friday
  • Contractor may work at night or on weekends, dependent upon additional construction activities or due to inclement weather.

 Important information

  • If a planned temporary water service shut-off is necessary, affected residents will be notified 48 hours in advance.  Service interruptions will be minimal.
  • Construction may cause temporary discolored water or low water pressure. If you experience discolored water, flush cold water taps for 15 minutes. If water does not clear, contact the DC Water Drinking Water Division or 24-hr Emergency/Command Center.

Traffic plans

  • Lane closures may be required daily with approved traffic plans by the District Department of Transportation (DDOT).
  • Notifications regarding “No-Parking” zones will be posted 72 hours prior to construction, in certain areas in and around the job site as required by DDOT.


DC Water is currently working closely with DDOT to ensure minimal disruption during this project.  Regular updates will also be provided to affected Advisory Neighborhood Commissions.
