Northbrook Sewer Systems

Storm & Sanitary Sewers


The Village of Northbrook owns and maintains two separate sewer systems; one for sanitary sewage and one for stormwater runoff. Sanitary sewage is made up of the waste water from inside homes and businesses from various plumbing fixtures such as sinks, toilets, dishwashers, and washing machines. Stormwater runoff includes water that drains overland from a property as well as that which is collected from streets, parking lots, sump pumps and footing tiles.

Sanitary Sewer System


The sanitary sewer system is made up of 124 plus miles of pipes and 13 lift stations which transport waste water to the Metropolitan Water Reclamation District's (MWRD) sewer system. Once in MWRD's sewer system, sewage is transported to and treated at MWRD's waste water treatment plant in Skokie, Illinois.
