Services & Process

Mainline Sewer & Septic covers the full range of what a septic system owner might need. Septic services include tank pumping, inspections, system troubleshooting, and drain field evaluation. Hydro-jetting clears pipe blockages using high-pressure water, which is especially effective for lines that have accumulated grease, sediment, or root growth over years of use. Excavation services mean they can dig to access buried tanks, repair collapsed lines, or install new system components without subcontracting that work to another crew. That in-house capability speeds up projects and keeps costs more predictable.

Service Area

Mainline Sewer & Septic is based in Antioch and serves Lake County, Illinois, including communities near the Chain O'Lakes, Gurnee, Waukegan, and the Wisconsin state line. The northern Lake County area has a high concentration of properties on private septic systems, keeping demand for professional service strong year-round.

Frequently Asked Questions

Does living near a lake affect how my septic system should be maintained?
Yes. Properties near lakes or in areas with high water tables need more careful management because a failing septic system can contaminate nearby water. More frequent inspections and pumping are generally recommended, and Illinois has specific setback requirements for septic systems near bodies of water.
What does a septic system excavation involve?
Excavation is needed when a buried component, like the tank lid, a collapsed pipe, or a damaged distribution box, has to be physically accessed or replaced. A company with its own excavation equipment can dig, complete the repair, and backfill the area without bringing in a separate contractor.
How do I know if my drain field is failing?
Signs of drain field failure include soggy or mushy ground above the field even during dry weather, sewage odors outside near the field area, and sewage backing up into the home. A professional inspection can confirm whether the drain field needs repair or replacement.
Can hydro-jetting clear roots from a septic line?
Hydro-jetting can cut through and flush out smaller root intrusions, but significant root growth may require a mechanical cutter first. After clearing, a camera inspection confirms whether the roots have been fully removed and checks for any pipe damage left behind.
What are Lake County's requirements for septic system inspections?
Lake County requires septic inspections as part of real estate transactions for properties with private systems. The county health department issues operating permits for septic systems, and sellers are typically responsible for ensuring the system passes inspection before closing.
How long does a septic system last in northern Illinois?
A well-maintained septic system in Illinois typically lasts 25 to 40 years, though drain fields can fail sooner if overloaded or poorly maintained. Regular pumping, avoiding flushing non-biodegradable materials, and keeping heavy vehicles off the drain field all extend system life.
