The Environmental Health Division is the authorized agent for IDPH to conduct all private sewage activities in Will County. The primary goal of the Sewage Disposal Program is to prevent the transmission of disease caused by exposure to sewage. In order to achieve this, division staff perform soil and site evaluations to determine soil suitability for the installation of private sewage disposal systems. Once suitability has been determined, septic permits are issued and staff conducts inspections of all new or repaired septic systems to ensure they have been installed according to the appropriate state and county regulations.
Continued compliance of discharging aerobic units is assured by sampling technicians from the Environmental Health Division's certified laboratory who routinely collect effluent discharges from the approximately 3,200 aerobic treatment systems throughout the county. The purpose of the sampling program is to ensure that the effluent quality meets the applicable county discharge limits. State and county regulations governing the installation, maintenance and discharge limits of private sewage systems may be found in the Illinois Private Sewage Code and the Will County Sewage Treatment and Disposal Ordinance which you can download below.
