Interactive Map Provides Real-Time Data on Sewer Overflows

Green banner with DPW logo and text "Department of Public Works Press Release"

With the Baltimore City Department of Public Works' (DPW) new interactive map, information on sanitary sewer overflows will be posted as soon as it is known. There will be no waiting for press releases or social media updates to obtain this important public health information.

The interactive map uses near real-time data to let the public know about sewer overflows in Baltimore City. The map is available on the DPW website: https://publicworks.baltimorecity.gov/interactive-maps.

This online map provides information on just-confirmed sewer overflows, and continues to display information up to four months. DPW’s map includes all known sewer overflows, regardless of location or size. An explanation and demonstration of the map was a feature of DPW’s second annual Sanitary Sewer Consent Decree public meeting on Wednesday, January 23.

Interactive map users will see:

  • Near real-time information
  • Watershed boundaries and waterways
  • Polluted water sign postings
  • Precise locations and click-on interactive stats
  • Up to four months of data
  • Numerous display options
  • ALL known overflows are shown

In addition, the map has a link to the City's Clean Drain Campaign, which encourages residents to properly dispose of fats, oils and grease (FOG), as well as wet wipes, in the trash instead of a drain to prevent sewer clogs. Citizens are also reminded to avoid contact with urban streams due to elevated levels of pollutants.

In 2017, DPW introduced an interactive map for water main repairs, which provides information on active water main repair activity in Baltimore City and Baltimore County, as well as those recently completed. It can be found here: https://publicworks.baltimorecity.gov/interactive-maps.
