Raleigh Township does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.
Private sewage (septic) systems on land inside Raleigh township, Saline County, Illinois, where no public sewerage system is reasonably available. The state rule-maker is the Illinois Department of Public Health under the Private Sewage Disposal Act; this is not a Raleigh township ordinance.
“the department shall promulgate and publish and may from time to time amend a private sewage disposal code which shall include minimum standards for the design, construction, materials, operation and maintenance of private sewage disposal systems”
Off-grid sanitation (no public sewer) for buildings inside Raleigh township, Saline County, Illinois.
“or if such sewerage system is not available then such disposal shall be in compliance with this act and the private sewage disposal code promulgated under this act”
Buildings where people live, work or assemble on land inside Raleigh township, Saline County, Illinois: sewer connection is required only where a sewerage system is reasonably available; otherwise a private system under the state code applies.
“human wastes and domestic sewage from such buildings and places shall be disposed of by discharging into a sewerage system operated and maintained under permit of the illinois environmental protection agency, if reasonably available”
We looked and could not find an official answer yet. Silence is not permission; ask Raleigh Township or Saline County directly.
Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.
Unanswered questions are usually a sign that Raleigh Township publishes no rule on the point, not that none exists. Saline County’s page lists the county offices to call.
