The District of Columbia Water and Sewer Authority (DC Water) is issuing a Boil Water Advisory today for some customers in Northwest DC that experienced a loss of water pressure on Friday, June 5, 2026, impacting 4,970 customers.
This is a precautionary notice to customers in the impacted neighborhoods to boil water prior to ingesting, due to water of unknown quality in this localized area of the system.
