When Chicago Clay Meets Septic Reality: Why Gage Park Homeowners Face Unique Drainfield Challenges

Homeowners in Gage Park face a perfect storm when it comes to septic system performance. Silt loam and silty clay loam textures are very common in Illinois, having formed in loess parent material. When clay content in soils exceeds 35% (heavy cl, heavy sicl, sic, or c textures), the soils are generally poorly suited for conventional septic systems because of slow permeability. This geological reality, combined with Chicago’s high water table and clay soil, creates significant challenges for traditional septic drainfield systems.

Understanding Clay Soil’s Impact on Septic Performance

Clay soil presents multiple challenges for septic system functionality. Clay soil is very compact and does not give room for the effluent to seep through. Clay soils can, therefore, result in backups in the leach field. The problem becomes even more complex when moisture is introduced. When wastewater effluent from a septic system infiltrates clay soils that have even relatively low levels (5-10%) of expansive clay minerals, the wet conditions will cause the soil to expand. This reduces the pore space within the soil structure, which will, in turn, diminish the ability of the soil in the drain field to absorb wastewater and hence its drainage capacity.

The consequences of clay soil on septic systems are serious. Clay soils with poor drainage will, therefore, have a reduced capacity to absorb effluent from a septic system, and will not be able to process wastewater effluent efficiently. The result is a reduced performance of the septic system, or even system failure, which can cause effluent to pool on the surface.

Chicago’s Geological Conditions: A Closer Look

Chicago’s unique geological makeup compounds these challenges. We understand how Chicago’s clay soil affects drainage and what that means for your maintenance schedule. Chicago’s clay soil can affect how quickly your system fills up. Additionally, Heavy rains can overwhelm septic systems in several ways, especially in areas like East Garfield Park with older infrastructure. When the ground becomes saturated, your drain field can’t absorb effluent properly, causing backups into your home. Chicago’s high water table and clay soil compound this problem.

The structural integrity of septic systems also faces threats in Chicago’s clay conditions. Furthermore, expanding clay soils with a COLE value greater than 0.06 (i.e. soils that are prone to swelling and shrinking) can cause structural damage to underground septic systems, which may require costly repairs.

Repair and Alternative Solutions for Clay Soil Challenges

Fortunately, several solutions exist for homeowners dealing with clay soil septic challenges. Poor Soil Drainage: If the natural soil has a low percolation rate (such as clay-heavy soil), a mound system provides additional filtration and drainage capacity. High Water Table: The raised design keeps the drainfield above the water table, reducing the risk of contamination.

Alternative septic systems designed for challenging soil conditions include:

• Sand Mound Systems: A sand mound septic system consisting of an above ground mound of porous sand media that serves as the drain field/filtration bed where effluent is processed. This sand media must be clean and clear of any silts or clay residues.
• Aerobic Treatment Units (ATUs): An aerobic treatment unit (ATU) will help process sewage before it is discharged into the drain field, to help prevent soil particles from becoming clogged up.
• Expanded Drainfields: A larger drain field provides a bigger assimilation system to make up for the reduced rate of drainage. This is a low-tech and relatively cheap option if you have the space available on your site to extend the drain field over a larger area.

Professional Assessment and Installation

Given the complexity of clay soil challenges, professional assessment is crucial. These limiting layers include bedrock, the seasonal high water table, dense soils with slow permeability, and sandy or gravelly soil with very rapid permeability. The State Code specifies that at least two feet of separation should exist between the bottom of the septic field and the limiting layer (three feet in coarser-textured soils). Installation of curtain drains, importation of fill material, or use of alternative sewage disposal systems are options that can be used where limiting layers occur at shallow depths.

Maintenance in Clay Soil Conditions

Clay soil conditions require more frequent attention to septic system maintenance. Most septic tanks in East Garfield Park should be pumped every 1-3 years, depending on household size and usage patterns. Chicago’s heavy rainfall and older infrastructure can put additional stress on septic systems, potentially requiring more frequent service.
