Baltimore Sewage Cleanup: City Expands Free Basement Disinfection Program

Baltimore will now provide free professional disinfection for residential basements damaged by sewage backups, regardless of whether the event was caused by weather or municipal system failure. Mayor Brandon M. Scott and the Department of Public Works announced the expansion of the Sewage Onsite Support program on Wednesday. This change extends coverage beyond the previous limits, which only applied to storm-induced emergencies.

The previous policy required homeowners or renters to prove that a heavy rainstorm caused the backup to receive aid. Under the new rules developed in coordination with the Maryland Department of the Environment, residents can now claim assistance for any sewage event resulting from the city’s infrastructure. The city cites the need to prevent the spread of pathogens and protect public health in vulnerable communities as the primary driver for this update.

Local officials stated that rapid disinfection is necessary to mitigate microbiological risks in households. The program eliminates the cost burden for professional cleaning services that residents previously had to pay out of pocket. By broadening the scope, the city aims to address health hazards arising from both wet-weather overflows and dry-day system malfunctions.

Affected residents can request the specialized service by dialing the city’s 311 hotline. The announcement marks a shift in how Baltimore handles sewage-related health risks, moving from a reactive storm response to a comprehensive infrastructure support model. The Department of Public Works confirmed that the expanded criteria are active immediately for eligible properties connected to the municipal sewer network.
