Pressure or uniform distribution of effluent is the optimum method to spread wastewater out to gain the best treatment from soil treatment systems.
With pressure distribution, effluent is delivered either to taps in a pressure manifold (pressure-dosed gravity systems) or to multiple points across an infiltrative surface (low pressure or drip distribution). By definition, pressure distribution systems incorporate a pump or siphon to provide the energy needed to overcome the forces of gravity. Pressure distribution systems using pumps can be dosed either on demand or at specific times. Those with siphons are inherently demand-dosed. Effluent can thus be distributed along the
