Water Main Break

September 01, 2004

The District of Columbia Water and Sewer Authority (WASA) is responding to a 16-inch water main break just west of the Duke Ellington Street Bridge in the Calvert -Woodley Park area in northwest DC.

The areas affected by the water main break are Cathedral Avenue – North Boundary; Connecticut Avenue – East Boundary; 24th Street – South Boundary; and Norman Stone Lane – West Boundary.

No structural damage to the bridge has been identified as a result of the main break.

Because of the location of the break, this is a particularly difficult and complex main repair that will require bringing in a specially equipped contract crew.

DC WASA is bringing water in from another water zone in an effort to maintain water pressure for our customers in the affected area. Nonetheless, residents in the area may experience fluctuating water pressure as a result of the repair work.

It may take several days to a week to complete the repairs and restore full service.

Residents with problems during this activity can contact the WASA 24-Hour Emergency Hotline at 612-3400

This website will be updated daily with information about the situation until service is fully restored.
