The Baltimore City Department of Public Works has stopped the recent sanitary sewer overflow (SSO) into Herring Run Stream (an area parallel to 5100 Perring Parkway), which discharged an estimated 55,400 gallons of sewage.
The SSO started the afternoon of Tuesday, Nov. 17 due to a break in a 21-inch sanitary sewer main. This break caused sewage to run into the stream from a sewer manhole. 

Due to difficulty accessing the SSO site, DPW was not able to completely stop the overflow until early Nov. 21. The area has steep slopes and is wooded, and required DPW to mobilize a contractor to build an access road to allow workers to reach the SSO site. Bypass pumping was used to abate the overflow.

The stream has been posted with warning signs, and the Maryland Department of the Environment and the Baltimore City Health Department have been notified.

Citizens are encouraged to avoid contact with urban streams due to possible pollution. Baltimore City is in the construction phase of the $1 billion Consent Decree rehabilitation of our sewer infrastructure.
