An estimated 570,000 gallons of sewage mixed with rain water was released into the Jones Falls on Tuesday, Aug. 15, due to water infiltrating the sewer system during the afternoon’s heavy rainstorm. This overflow event followed one on Saturday, Aug. 12, also caused by infiltration from rain.

Almost all of the overflow volume on Aug. 15 occurred at two structured, underground outfalls: 428 E. Preston St. (464,500 gallons) and North Charles Street and West Lanvale Street (103,500 gallons). A small overflow occurred at 1901 Falls Road.

Structured overflows were designed into the City’s sewer system more than 100 years ago to provide such releases when the sewers became inundated with rainwater. They are being eliminated as part of the City’s sewer system consent decree.

The Baltimore City Health Department and the Maryland Department of the Environment were notified of the releases.

The public is reminded to avoid contact with urban waterways due to the risk of pollution. For information about health concerns as a result of sewer overflows please go to http://health.baltimorecity.gov/sanitary-sewer-overflows-sso.
