I saw one in a sanitary sewer this weekend in Northern Michigan.

Storm - sanitary - combination - forced - gravity

The two main types of sewer systems are the sanitary sewer system and the stormwater sewer system. They are different because sanitary sewer system has water from sinks, baths, washing machines, and toilets and the stormwater sewer system has water from the rain or melted snow that run off streets and the surface of the land.

There are four major types of sewage disposal systems. The septic tank, the domestic sewer, the storm sewer, and the sanitary sewer are the major types.
