Over 3 million gallons of sewage flows into Baltimore waterways

BALTIMORE, Md: - Baltimore City public works officials said sewage overflow caused by massive rainfall earlier this week exceeded earlier estimates by dumping over three million gallons of sewage into Maryland waterways.

 The Baltimore City Department of Public Works previously reported an overflow at the Patapsco Wastewater Treatment Plant on Tuesday, Aug. 12 was under 3 million gallons.  

A related sewage overflow less than a half mile away, at a pumping station at Patapsco Avenue and Shell Road, was identified late that evening and was stopped in the early morning hours of Thursday.

That incident resulted in approximately 170,300 gallons being spilled. Both overflows went into the Patapsco River.

A rainfall of 6.3 inches that afternoon was the second-highest one-day total for Baltimore on record. The volume of water overwhelmed systems designed to move it, causing flooding, and infiltrated the city's sanitary sewer system.

DPW crews also responded to a handful of smaller overflows.

The Department of Public Works encourages residents to report suspected sewer overflows to 311. The Maryland Department of the Environment and the Baltimore City Health Department have been notified of these events.
