Division of Environmental Health

Private Sewage

Malfunctioning or improperly constructed and maintained private sewage disposal systems can pose serious health hazards. The division regulates all private sewage disposal systems that have no surface discharge (such as septic tanks and seepage fields) as well as those that discharge up to 1,500 gallons per day to the ground surface or to streams (such as sand filters and aerobic treatment systems). Staff also review and approve plans for private sewage disposal systems before construction. There are about 90 local health agencies in Illinois that also review sewage disposal system construction plans, either by authority of a local ordinance or as an "agent" of the Department. In addition, the division licenses about 2,700 individuals who either install or pump out private sewage disposal systems.
