What is a consequence of high groundwater levels on septic systems?

High groundwater levels can significantly reduce the effectiveness of septic systems, particularly the drain field. A septic system relies on soil to filter and treat the effluent that is released from the tank. When the groundwater is high, the soil surrounding the drain field can become saturated. This saturation creates a situation where there is insufficient space for the effluent to be absorbed and treated effectively.

In such cases, the drain field may not be able to adequately process the wastewater, which can lead to effluent surfacing on the ground or backing up into the septic tank. As a result, the overall functionality and efficiency of the septic system deteriorate, potentially leading to system failures, environmental contamination, and health risks.

Understanding the relationship between groundwater levels and septic system function is crucial for proper installation and maintenance, ensuring that systems operate effectively and comply with health regulations.
