WSSC Water Crews Responding to a Sanitary Sewer Overflow in Rockville

Crews Worked Throughout the Night to Remove Downed Trees and Build Access Road to Overflow Area

| News Release



Drinking Water System Not Impacted


Laurel, Md. – February 28, 2020 – WSSC Water crews worked throughout the night to gain access to an ongoing Sanitary Sewer Overflow (SSO) in a wooded area near 11604 Parkedge Drive in Rockville. The SSO was discovered yesterday shortly after 5:30 p.m. Since that time, crews have been removing downed trees and building an access road to the overflow location. The overflow is continuing at this time and running into Old Farm Creek.

With downed trees removed and the access road constructed, crews are in the process of establishing a temporary bypass pumping operation, which will stop the overflow by moving the wastewater around the overflowing section of 18-inch diameter pipe. It is unclear at this time the cause of the overflow or how much wastewater has entered the creek. Updates will be provided as soon as possible.

It is important to note that the water and wastewater systems are separate. This overflow is NOT affecting WSSC Water’s drinking water.

WSSC Water has made appropriate notifications to the Maryland Department of the Environment and the Montgomery County Health Department. WSSC Water crews will clean up and post signs warning the public to avoid area once repairs are complete.
