Abstract: An improved water distribution system of the type that includes a distribution conduit and an irrifluent pipe disposed on or below ground for dispersing water at a controlled rate. A first pump connected to the distribution conduit passes the water through the main delivery conduit and through apertures in the irrifluent pipe. Solid matter collects within the irrifluent pipes when the dispersion of the water through apertures in the irrifluent pipes is at low pressure. The improvement includes a return conduit that is disposed in fluid communicating relation to the irrifluent pipe, and a second pump, connected in fluid flow relation to the return conduit. The second pump is operated intermittently with the first pump to increase the flow rate sufficiently to flush the collected solid matter from the irrifluent pipes and through the return conduit.

Abstract: An improved water distribution system characterized by a construction including an irrifluent pipe disposed below the soil surface for dispersing water or treated waste water at a controlled rate. The irrifluent pipe includes an inner fluid conduit having apertures formed therethrough and an outer cover mounted in partially surrounding relation to the inner conduit and overlying the apertures. The outer cover is attached to the inner fluid conduit in spaced apart relation thereto so that the dispersed fluid slowly seeps into the ground.
