UPDATE: DC Water Lifts Boil Water Advisory for All Affected Customers – Effective 5:00 a.m. May 10, 2024

May 10, 2024

All DC Water customers in the impact area under the boil water advisory can use tap water for all purposes after following the instructions provided below.

DC Water issued the boil water advisory as a conservative measure to protect public health, and we sincerely appreciate our customers’ patience while we took necessary precautions to ensure the safety of the tap water we deliver.

DC Water lifted the boil water advisory after tests confirmed that drinking water meets all water quality safety standards. DC Water tested water samples from multiple sites in the affected area and has verified that there is no risk of water contamination from the loss of pressure in some portions of the distribution system.  

The advisory affected 4,800 customers in some neighborhoods in Upper Northwest D.C. Please see the interactive map at dcwater.com or call the 24-Hour Command Center at ( 202) 612-3400 to verify if your address was in the affected area.

Customers residing in the previously affected area should take the following precautions before returning to normal water usage:

•    Run the cold water taps for 10 minutes (if water was not used at all during the advisory).
•    Discard food, beverages or ice prepared with water that was not boiled during the advisory.

Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this public notice in a public place or distributing copies by hand or mail.

DC Water will work with customers to answer questions and respond to additional issues following the Boil Water Advisory. Customers with water quality questions should contact the Drinking Water Division at (202) 612-3440 (Monday through Friday, 8 a.m. to 4:30 p.m.)

All other questions or suggestions should be directed to DC Water Customer Service at 202-354-3600 (Monday through Friday, 8:00 a.m. to 5:00 p.m.) or the 24-Hour Command Center at 202-612-3400.

Tree and debris removal for environmental rehabilitation

Work is nearly complete on the downstream section of the Potomac Interceptor to reinforce the pipeline with geopolymer. The concrete-like material will strengthen and restore the structural integrity of the pipe. Completion of the geopolymer lining downstream is one of the final steps to restore flow to the interceptor and finish the emergency repair.

This comes one month since the last overflow reached the Potomac River.

geopolymer downstream

As emergency repairs continue, today marks 27 days, nearly one month, with no overflow reaching the Potomac River.

Crews are making significant progress to reinforce the downstream section of pipe from the collapse site and completed 240 linear feet of geopolymer overnight. Crews are working to apply another layer of geopolymer today. The material is similar in strength to concrete and when applied restores the structural integrity of the pipe.
