Brentwood Reservoir Rehabilitation and Upgrade Project


DC Water’s Brentwood Reservoir is an underground reinforced concrete structure for potable water storage that was first put into service in 1959. The Brentwood Reservoir has a capacity of approximately 25 million gallons and is located in northeast DC. DC Water is making upgrades to the Reservoir and associated water infrastructure.


Among other detailed work activities, this project will include ventilation improvements at the Brentwood Reservoir.

  • Contractor may work at night or on weekends, depending on needed construction activities or inclement weather


  • 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-Hour Command Center.


  • Lane closures may be required daily and will be done in accordance with traffic plans approved by the District Department of Transportation (DDOT).

DC Water is currently working closely with the National Park Service (NPS) and will coordinate with other District and Federal agencies to ensure minimal disruption during this project.
