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.

Laterals 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 they drain into the sewer system your city or village owns.

City Sanitary Sewers make up another 3,000 miles of sewer pipe in the region.  MMSD serves 28 communities that all own and operate sanitary sewer systems.

MMSD Sewers, about 300 miles of pipe, transport wastewater to one of two regional water reclamation facilities where the water is cleaned and returned to Lake Michigan.
