Septic Tank Tips for Chicago

Illinois EPA and individual county health departments regulate septic installations — McHenry, Kane, and DuPage counties on Chicago's outer ring have many rural septic properties

Chicago's clay-heavy soils have notoriously poor percolation — mound systems are common in exurban areas and add significant cost to installations

Frost depth in northern Illinois can affect pump chambers and shallow system components — ensure your installer accounts for freeze protection in the design
