How does soil percolation rate affect drainfield design?

Soil percolation rate tells you how fast the soil can infiltrate wastewater. In drainfield design, this rate determines the required area: slower percolation means you need a larger drainfield or an alternative system to provide enough soil contact and treatment. It doesn’t govern the effluent’s pH, nor does it directly dictate the dosing tank depth, which is set by hydraulic loading and system layout. The main takeaway is that slower infiltration requires more area or a different system to achieve proper treatment.
