If you own a house, you own part of the sanitary sewer system that helps protect public health. The section you own is called a lateral and it connects to the sewer system owned by your city or village.
Account for 3,000 miles of sanitary sewer pipe in the MMSD service area. They transport all the water you use in your home out to the street where it drains into the sewer system your city or village owns.
Make up another 3,000 miles of sewer pipe in the region. MMSD serves 28 communities that all own and operate sanitary sewer systems.
About 300 miles of regional sewer pipes that transport wastewater to one of two water reclamation facilities where the water is cleaned and returned to Lake Michigan.
We also have the Deep Tunnel system, which is 28-miles long and ranges in size from 17 feet to 32 feet in diameter.
