Expert Drain Field Installation & Repair Services for Homes & Businesses in East Central IL
Your septic system’s leach field — also known as a drain field — is one of the most critical components of your wastewater treatment system. When it’s working properly, it quietly and effectively filters and disperses treated water into the soil. But when it fails, you may notice soggy spots in your yard, unpleasant odors, or even sewage backing up into your home.

What Is a Leach Field?
A leach field (or drain field) is a vital part of your septic system. After wastewater leaves your septic tank, it flows into the leach field, a series of underground pipes that distribute the treated water into the soil for natural filtration.
When a leach field becomes clogged or damaged, or was incorrectly sized for your home, your septic system can back up, create foul odors, or saturate your yard with untreated wastewater.
FAQs About Leach Fields
A leach field, also called a drain field, is a series of perforated pipes buried in gravel-filled trenches. Wastewater from your septic tank flows into these pipes and seeps into the surrounding soil, where it’s naturally filtered and treated by microbes before returning to the groundwater.
Costs depend on several factors: the size of your household or business, soil conditions, the type of leach field system, and site accessibility. In the East Central IL area, we’re happy to visit your property, evaluate your needs, and provide a detailed, honest quote.
No — you should never build driveways, patios, sheds, or plant trees over your leach field. Heavy weight, roots, and soil compaction can damage the pipes and soil structure, leading to costly failures.
Most conventional septic systems rely on a leach field to disperse treated water. However, on properties with poor soil or limited space, we can install alternative systems, like mound or aerobic systems, to meet local regulations and environmental needs.
A properly designed and maintained leach field can last 20–30 years, sometimes longer. Regular septic tank pumping, avoiding excess water use, and keeping heavy vehicles off of the field all help extend its life.
