Reported Sewer Overflows (New for 2023)

This report has replaced the opendata.maryland.gov/Energy-and-Environment/Reported-Sewer-Overflows/3rgd-zjxx/about_data Reported Sewer Overflows. This report contains overflows from February 10th, 2023, onward. Although MDE requires that all public sewer system owners or operators report overflows to us, there may be incidents that were not reported.

Note that overflow amounts provided by the person reporting the overflow may be estimated using best professional judgment or they may be actual readings from flow measurement devices when available.
