What is recommended when using dosing in high clay, group 4 locations?

In high clay, group 4 locations, implementing a dosing system is recommended due to the physical properties of clay soil. Clay tends to retain water and has low permeability, which can lead to slow drainage and increased risks of system failure if not managed properly. A dosing system allows for the controlled distribution of effluent over time, preventing saturation in the soil and minimizing the risk of clogging. This system can help facilitate the treatment process by allowing the soil to absorb effluent at a rate that matches its absorption capacity, making it suitable for high clay environments.

Regular maintenance intervals and periodic testing of soil are important practices for any septic system, but they do not directly address the unique challenges posed by clay soil. Direct discharge would not be appropriate in these settings, as it could overwhelm the surrounding soil, leading to potential environmental contamination and system inefficiency. Therefore, implementing a dosing system is crucial for effectively managing wastewater in these challenging soil conditions.
