FOR IMMEDIATE RELEASE

Laurel – June 23, 2014: The total amount of a Sanitary Sewer Overflow (SSO) into Charles Branch Creek in Upper Marlboro, which was confirmed at 10:45 p.m. on Friday, June 21 and ended on Sunday, June 22 at 12:30 p.m. was 73,134 gallons. The SSO ended when WSSC contractors were able to gain access to the break and setup a bypass around the broken section of 24-inch sewer main while repairs are made.

During the SSO, a majority of waste was re-entering a section of the same broken pipe downstream at an undetermined rate. The creek bed beneath the sewer main deteriorated, undermining the pipe's support to the point that it ruptured. The area where the break is located is remote and wooded, which required the construction of a temporary access road. With overpumping in place, crews will now turn to replacing the broken sewer main. With the bypass in place, crews will now turn to replacing the broken sewer main. The bypass will remain in place until repairs are complete.

Notifications have been made to the Maryland Department of the Environment and the Prince George’s County Department of the Environment. WSSC crews have posted signs and will perform all necessary cleanup in the affected area.
