Overflows in Halethorpe and Catonsville Stopped Within Hours

Baltimore County’s Department of Public Works reported and corrected two sanitary sewage overflows in the County's southwest area following Sunday’s flooding.

The Patapsco Sewage Pumping Station, located at 4612 Annapolis Road in Halethorpe, 21227, was overwhelmed by the storm at 10:32 p.m. Sunday night and discharged 607,000 gallons into the Patapsco River. The overflow was stopped at 2:47 a.m. Monday morning.

The Frederick Road Pumping Station, located at 1809 Frederick Road in Catonsville, 21228, released 47,000 gallons into the Patapsco River. The overflow began at 4:10 p.m. on Sunday afternoon and ceased at 10:08 p.m. that evening.  

The sanitary sewage discharges were due to increases in volume caused by the storm which exceeded the capacities of both stations. When volumes receded, full operations were restored.

As a precaution, contact with the waters of the Patapsco River should be avoided. The Baltimore County Department of Health will issue water contact advisories when necessary on the Department of Health Department's website


Public advised to avoid contact with water while Department of Health monitors water quality

A sanitary sewer overflow was discovered late Tuesday morning in a wooded area north of Coppermill Court in Owings Mills. Crews from Baltimore County’s Bureau of Utilities responded to contain the discharge from a sewer manhole. They worked through the day to establish a pump-around using three pumps. The release was stopped by 10:45 p.m. Tuesday night.

The sewage overflow, estimated at 212,500 gallons, was apparently the result of damage from stream debris to two manholes which happened during recent, hard rains. Debris entered the damaged manholes and blocked an 18-inch diameter pipe.

The overflow occurred in a densely wooded area, from a manhole located in a tributary to the Gwynns Falls. Utility crews are liming and cleaning up the area, but the public is advised to avoid contact with the water. The Baltimore County Department of Health is monitoring water quality in the area and has issued a water contact advisory on the Department's website:
