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.

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.
