WSSC Water Crews Stop Sanitary Sewer Overflow in Rockville

Work Continues to Repair Sewer Main and Determine Cause

| News Release



Reminder: Drinking Water System Not Impacted

Laurel, Md. – February 28, 2020 (4:45 p.m. Update) – WSSC Water crews worked around the clock to stop a 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. and was stopped at 9:30 a.m. today. The total volume of the overflow is estimated to be 19,020 gallons of untreated wastewater that flowed into Old Farm Creek.

An extensive bypass operation has been established to pump wastewater around the section of 18-inch diameter sewer pipe that was overflowing, and will remain in place until crews can determine the cause and make necessary repairs.

A significant number of downed trees had to be removed from the area and an access road was constructed, allowing contractors to reach the site and set up the temporary bypass pumping operation.

The impacted area has been cleaned up and crews applied lime to mitigate the odor. Eighteen signs have been posted alerting residents to avoid the area. Once repairs are complete, crews will restore the area.
It is important to note that the water and wastewater systems are separate. This overflow did NOT affect WSSC Water’s drinking water.
