Out of all the rain, melting snow and stormwater that entered MMSD’s regional sewer system in 2014, the District captured and cleaned 99.5%.

The goal nationally for communities with combined sewers is to capture and clean 85% of all the water that enters the sewer system.

MMSD’s water reclamation facilities, combined, cleaned 68.3 billion gallons of water last year, returning it to Lake Michigan.

To reduce the risk of basement backups during heavy rain, the District did have two combined sewer overflows, totaling 341 million gallons.

Since the Deep Tunnel started operating in 1994, MMSD has captured and cleaned 98.3% of all water that entered the regional sewer system.
