UPDATE: DC Water Lifts Boil Water Advisory for All Affected Customers – Effective 7:30 AM July 4, 2024

July 04, 2024

All DC Water customers under the precautionary boil water advisory can use tap water for all purposes after it was confirmed that drinking water provided by the Washington Aqueduct never deviated from U.S. EPA established water quality standards as had been anticipated.

Under advice from the Washington Aqueduct, DC Water issued the precautionary 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.

The advisory affected all customers in the District of Columbia, as well as the Pentagon, Arlington National Cemetery and Reagan National Airport. Arlington County customers were also impacted.

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. Questions can 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. Information is also available at dcwater.com and Bilingual FAQs are provided at www.dcwater.com/boilwaterFAQ.

Today, DC Water completed construction on a temporary bypass system as part of sewer repairs on the Potomac Interceptor near Pennyfield Lock in Potomac, Maryland. Crews turned on the pumps and successfully tested the system.

Today, DC Water broke ground on the Piney Branch Tunnel, the final major tunnel in our Clean Rivers Project. This work will help keep sewage and trash out of local waterways and make Rock Creek, the Potomac River, and the Chesapeake Bay cleaner for our community.

When we finish the Piney Branch Tunnel, it will hold at least 4.2 million gallons of rainwater and wastewater during heavy storms. Instead of overflowing into Piney Branch, that water will go to the Blue Plains Water Resource Recovery Facility, where it will be treated.

Starting the week of July 13, 2026, people who live, work or travel near the Canal Road NW entrance to Georgetown University may hear controlled blasting. This work is part of our Potomac River Tunnel Project.

When blasting happens, neighbors may hear a brief noise or feel light shaking. Drivers, cyclists, and pedestrians on Canal Road NW may also be stopped for a few minutes while we safely complete each blast.
