Sanitary Sewers

The Village of Oak Lawn’s Sewer Department maintains over 120 miles of sanitary mains which are interconnected with over 4,100 sanitary manholes & four lift stations. These sewers collect the wastewater from homes & businesses throughout the Village of Oak Lawn & eventually flow to the Metropolitan Water Reclamation District of Greater Chicago’s (MWRDGC) Main System.

 

Storm Sewers 

The primary function of the Sewer Division is the maintenance & repair of the sewer system throughout the Village of Oak Lawn. It is composed of two separate entities, a sanitary system and storm water system. The sanitary system handles the wastewater or sometimes referred to as (dirty water). The storm system handles the run off from rain water and is often referred to as (clean water).
