TL;DR
Pressure distribution is a septic drainfield design that uses a pump to push effluent through small-diameter perforated laterals in timed doses, wetting the entire field evenly instead of letting gravity overload the first few feet of trench. The uniform, intermittent dosing preserves the soil's treatment capacity and is commonly required for shallow soils, sand mounds, and sites with marginal separation to groundwater.

Pressure distribution is a septic drainfield design that uses a pump to push effluent through small-diameter perforated laterals in timed doses, wetting the entire field evenly instead of letting gravity overload the first few feet of trench. The uniform, intermittent dosing preserves the soil's treatment capacity and is commonly required for shallow soils, sand mounds, and sites with marginal separation to groundwater. The pump tank and floats add components a gravity system never needs.
