FOR IMMEDIATE RELEASE

Laurel, Md – April 19, 2018 – WSSC crews are working to determine the cause of a sanitary sewer overflow that began Thursday morning in the 4600 block of Annapolis Road near the Bladensburg Waterfront Park in the Hyattsville area of Prince George’s County. The overflow ended at approximately 11:49 a.m. The volume, which will be calculated based on wastewater flow data, is expected to be in excess of 10,000 gallons.

Crews arriving on the scene this morning found a significant amount of oil mixed with wastewater overflowing from a manhole near the Hyattsville Wastewater Pumping Station. It is possible that the oil caused a blockage in the sewer main, causing the overflow. WSSC crews are in the process of setting up a system to bypass the wastewater around the site of the blockage to inspect the pipe and determine the exact cause.

WSSC crews diverted the wastewater into an unlined storage pond located next to the pumping station. It is possible that diluted wastewater could impact the Anacostia River. WSSC is encouraging residents to avoid contact with the river in this area and downstream from the park. WSSC will post signs in the area affected by the overflow.

It is prohibited to discharge any wastes containing petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin that could cause a sanitary sewer overflow.

Notifications have been made to the Maryland Department of the Environment, the Prince George’s County Health Department and the Prince George’s County Department of Parks and Recreation.

It is important to note that WSSC’s water and wastewater systems are separate. Sanitary sewer overflows do NOT affect WSSC’s drinking water.
