The state of Illinois has several different types of septic systems that are allowed, depending on the site conditions and the needs of the property. For a comprehensive overview of the guidelines for septic systems in IL, the Illinois Private Sewage website shares many useful resources.
These are the most used in Illinois:
Conventional septic systems: These systems are the most common and consist of a septic tank and a drain field. The septic tank is used to separate solid waste from liquid waste, and the liquid waste is then discharged into the drain field.
Alternative septic systems: Alternative septic systems are designed to handle certain site conditions that may not be suitable for a conventional septic system. Some examples of alternative septic systems include aerobic treatment units, which use oxygen to break down waste, and sand filters, which use a layer of sand to filter waste.
It's important to note that the type of septic system allowed will depend on the specific site conditions and regulations of the county or municipality where the property is located. Vinson and Sill, Inc. consults with USDA Soil Scientists to pull data samples from the proposed setpic site for reports which are shared with the county of septic installation.
Once soil conditions are reported, our team of experts work with county officials to determine the septic system options we are able to present to the home owner.
The cost of a new septic system can vary depending on a number of factors, such as the type of septic system, the size of the system, the cost of labor, and the specific site conditions of the property. On average, a new septic system can cost anywhere from $5,000 to $20,000 or more.
Here are a few factors that can impact the cost of a new septic system:
1. Type of septic system: The cost of a septic system can vary depending on the type of system you choose. A traditional septic system, such as a conventional septic system or a low-pressure pipe system, will typically be less expensive than an alternative septic system, such as an aerobic treatment unit or a sand filter.
2. Size of the system: The size of the septic system will also impact the cost of the replacement. A larger system will cost more than a smaller one.
3. Installation costs: The cost of labor can vary depending on where you live and the complexity of the installation.
4. Site conditions: Some site conditions can make the installation more complex, such as rocky soil, steep slope, or high water table, which can add to the cost of installation.
5. Permits and inspections: The cost of permits and inspections will vary depending on the regulations of your local
