Sanitary Sewer System

The Public Works Department operates and maintains 68 miles of sanitary sewer along with four lift stations, and an excess flow facility. The Park Forest sanitary sewer system is divided into three subsystems, The North, Central, and South systems. Each of these areas flow to separate trunk sewers where the wastewater is then conveyed to Thorn Creek Basin Sanitary District for treatment.

The Department of Public Works is responsible for the structural integrity and proper function of the sewer system. This is accomplished by routine sewer cleaning, sewer televising, sewer replacement, and sewer lining.

Homeowners and contractors who need to repair a private sanitary sewer drain/line or desire to install an outside sewer clean-out on private property need to apply for a sanitary sewer permit. Please see below for the requirements to obtain a permit:

  • Contractors need to be licensed to work within the Village of Park Forest.
  • Submittal of a copy of the Contractor's proposal with the homeowner/property owner's signature.
  • Fee of $60.00 to be paid to the Village of Park Forest upon permit application submittal.
