ABSTRACT:
A drip field manifold system comprises an upper manifold, a flush manifold and a plurality of drip lines operatively connected to the upper and flush manifolds. The upper and flush manifolds are disposed vertically above the upper most drip line in a drip field to isolate the drip lines from one another during periods of suspended effluent flow from a waste water treatment system, preventing back flow of effluent through the manifolds to the lower most drip line and resulting over saturation of the drip field.
