Laurel, Md. – November 19, 2021 – WSSC Water crews quickly responded to and stopped a Sanitary Sewer Overflow (SSO) in a wooded area near Sangamore Road and Macarthur Boulevard in Bethesda. The overflow was detected on Wednesday, November 17, at approximately 5:35 a.m. and ended on Thursday, November 18, at 3:15 p.m.

Grease and wipes caused the overflow, which resulted an estimated 10,101 gallons of untreated wastewater to flow into a nearby dry impoundment area, keeping it from entering Little Falls Branch. WSSC Water crews cleared the blockage of grease and wipes and will set up a bypass pumping operation to move wastewater around the section of pipe to allow for a more comprehensive cleaning of the sewer main.

Area residents may notice an odor near the SSO location. Signs warning residents to avoid the area have been posted. Once repairs are complete, crews will clean and restore the impacted area.

WSSC Water has made appropriate notifications to the Maryland Department of the Environment and the Montgomery County Health Department.
