What is the maximum length allowed for an absorption trench in conjunction with dosing tanks?

The maximum length allowed for an absorption trench in conjunction with dosing tanks is indeed 125 feet. This limitation is established to ensure proper drainage and effective treatment of wastewater within the trench. Longer trenches could potentially lead to issues such as inadequate absorption due to soil saturation or reduced performance of the septic system, as longer distances might not allow the effluent to percolate effectively.

By maintaining a maximum length of 125 feet, the design encourages optimal flow dynamics and maximizes the chances that effluent is treated adequately before entering the surrounding soil. This regulation helps in preventing system overloads and contributes to the overall sustainability of the septic system.
