DC Water Secures 10 Consecutive Years of a “AAA” credit rating from S&P

The District of Columbia Water and Sewer Authority (DC Water) has once again secured high credit ratings from all three major rating agencies—S&P Global Ratings, Moody’s Investors Service, and Fitch Ratings—further strengthening our position as a national leader in public utilities.

To our neighbors, community partners, and everyone who cares deeply about the Potomac River and our shared commitment to the Potomac River.

Work remains ongoing, and protecting public health and the Potomac River continues to be the top priority of DC Water.

Pumping capacity remains a challenge, due to ongoing maintenance and operational issues. An overflow occurred late Monday night, when two pumps – clogged with non-disposable wipes – were taken out of service for cleaning and maintenance. During a period of high flow, the volume of wastewater temporarily exceeded pumping capacity resulting in the overflow.

The overflow did not enter the Potomac River and was contained on-site by an earthen dam and a trench system that captured and redirected the wastewater back into the sewer system.
