This is an engineered drop trench Eljen septic system. This is a type of onsite wastewater treatment system designed for areas where traditional septic systems may not be suitable due to site limitations, such as high groundwater levels, poor soil conditions, or small lot sizes.
Eljen systems utilize a combination of passive filtration and aerobic treatment to purify wastewater before it is released into the soil. The "drop trench" component refers to the trenches excavated in the soil where the wastewater is distributed for treatment. These trenches typically contain a series of proprietary Eljen components, such as stacked filtration modules or infiltrator chambers, which promote the treatment of wastewater as it percolates through the soil.
Engineered Eljen systems are designed based on site-specific conditions and may require approval from your county health department. They are often used in residential and commercial applications where conventional septic systems are not feasible or permitted. These systems can offer advantages such as smaller footprint, reduced environmental impact, and improved treatment efficiency compared to traditional septic systems. However, they may also require periodic maintenance and monitoring to ensure proper operation and compliance with regulations.
