New Septic Systems for Bourbonnais Properties
A new septic system is a long-term investment. Getting it right means a proper site evaluation, a design that fits your property and a permit approved before any digging starts.
Septic companies that work across Kankakee County can guide you through each step and handle much of the paperwork.
From soil test to finished system
A septic installation starts with a soil and site evaluation, which decides what kind of system the lot can support. A designer then sizes the system for the number of bedrooms, the plan goes to the Kankakee County health department for a permit, and the installer digs, sets the tank and builds the drain field before a final inspection.
Choosing the right system
The best system is the one your soil and lot can support. Good, deep soil often allows a conventional system. Clay, high groundwater or shallow bedrock may call for a mound, pressure distribution or an aerobic unit. Each has different costs and maintenance needs, so ask your installer to explain them.
The permit process for a new system
Installing or replacing a septic system almost always needs approval from the Kankakee County health department or the state agency that oversees septic systems. The usual steps are a soil evaluation, a stamped design, plan review and one or more inspections during construction. Starting without a permit can mean digging it all up again.
Why installation prices vary
Soil and site conditions drive most of the difference. A flat lot with deep, well-drained soil is simpler than a sloped lot with clay or high groundwater. Access for equipment and the distance from the house also matter.
Getting the most from your new system
Good habits protect your investment: spread out laundry, fix leaks promptly, avoid flushing wipes and grease, and pump on schedule. If your system has an alarm, learn what it means and who to call.
Questions to ask an installer
Ask who performs the soil evaluation and design, whether they handle permits, what system types they recommend and why, and how long the project will take. Ask about warranty terms and what maintenance the system will need.
Getting ready for installation day
Clear access for equipment, mark wells, underground utilities and sprinkler lines, and plan where soil and materials will be staged. Your Bourbonnais installer will call in utility locates before digging. Expect some disturbance to the yard, which is regraded and seeded or restored as part of the job.
Questions that prevent problems later
Before work begins in Bourbonnais, ask where the tank and field will sit relative to your well, your neighbors and any planned projects. Ask how deep the components will be, how the yard will be restored and what records you will receive when the job is done. Clear answers now save digging up the yard later to find out.

What Bourbonnais's soil means for a new system
The USDA soil survey rates most mapped soils near Bourbonnais as very limited for septic absorption fields. New systems here often need a mound, pressure distribution or another engineered design, which your soil test will confirm. Bourbonnais averages about 39 inches of precipitation a year, which your designer will factor into where the system goes. About 3 months below freezing mean pipes and components must sit deep enough or be insulated, and installation is usually easiest outside winter.
Local conditions in Bourbonnais that affect septic installation
Among the mapped soils within about two miles of central Bourbonnais, the USDA soil survey rates 97% as very limited for septic absorption fields, 3% as somewhat limited and 0% as not limited. The most common drainage class is moderately well drained. Soils like these often call for careful system design, such as a larger drain field, a mound or another engineered system, and a site evaluation before any new installation or replacement.
Bourbonnais averages about 39 inches of precipitation a year, and June is usually the wettest month. Average temperatures stay below freezing for about 3 months a year, with January averaging 24°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.

- Installation itself often takes a few days to two weeks. Soil testing, design and permit review can add several weeks, so plan ahead.
- What is a mound system?
- A mound system raises the drain field above the natural soil using sand and fill. It is used where the soil is too shallow, too wet or too slow draining for a conventional field.
- Can a replacement system go in the same place?
- Sometimes. It depends on the condition of the soil in the old field and local rules. Many replacements use a new area of the yard.
- Who approves septic installations in Bourbonnais?
- Septic permits are usually handled at the county or state level. Contact the Kankakee County health department to confirm the requirements for your property.
