Sanitary Sewer & Storm Sewer Overview
Storm Sewers: Are designed to convey rainwater and groundwater flows to nearby water bodies. They are owned and maintained by municipality and are typically located within public road rights-of-way or private property easements.
Sanitary Sewers: Receive wastewater flows from buildings (i.e., from sinks, toilets, and drains) and convey it to sewage facilities. They are owned and maintained by municipalities and are typically located within public road rights-of-way or private property easements. Sanitary sewer laterals convey the wastewater from buildings to the sanitary sewer.
Sanitary Sewer Laterals: Convey wastewater flows from buildings to the sanitary sewer system. Examples of the wastewater include flows from the building's internal plumbing fixtures, such as toilets, showers, sinks and washing machines.
Foundation Drains: Are perforated pipes that are installed around buildings at a depth below that of the building's foundation. They convey groundwater to the storm sewer and are designed to prevent buildings from flooding.
Roof Drains: Are used to convey rainwater from a building's roof to the storm sewer system.
Catch Basins: Are designed to collect rainwater runoff from roads and other paved surfaces. The rainwater enters the storm drains and is conveyed to a storm sewer.
