MSD made a commitment through the Integrated Overflow Abatement Plan (IOAP) and MS4 Permit to use green infrastructure to aide in helping control the amount of water that goes into our sewer system. This also helps reduce sewer overflows. MSD offers several programs to better involve the community in implementing green infrastructure throughout our community in a joint effort to improving water quality.

Illicit connections to the sewer system can cause sewer overflows, which lead to pollution problems in our waterways. These connections let rainwater from gutters and downspouts flow directly into a sanitary or combined sewer. Improper connections increase the volume of water in the sewer system, contribute to sewer overflows that pollute our waterways and cause sewer backups into homes. read more
