Frequently Asked Questions

How do I find a reputable septic service company in Illinois?

Look for companies licensed by the Illinois Department of Public Health (IDPH) as private sewage disposal contractors, insured, and experienced with your type of system. Ask for references, and verify their credentials. Your local board of health can provide referrals to licensed contractors in your area.

What septic services should I schedule regularly?

At minimum, have your tank pumped every 3-5 years and inspected at the same time. Annual inspections are recommended for systems with mechanical components like pumps or aerators. Keep records of all maintenance — many states require maintenance records for certain system types.

Are septic service companies in Illinois licensed?

Yes, most states require septic haulers to hold a valid permit from the state environmental agency. Installers and repair contractors must be licensed by the local board of health. Always verify a company's credentials before hiring.
