Abstract:
A system for fluid distribution into subsurface soil, comprising:a wide core set having a width greater than a first width and comprising two adjacent wide core sheets in face to face relationship, each wide core sheet having a top edge, a bottom edge, a first outside edge connecting the top edge to the bottom edge and an opposing second outside edge connecting the top edge to the bottom edge, means for spacing the adjacent wide core sheets, and fluid pervious fabric disposed between one said wide core sheet and the means for spacing the adjacent wide core sheets; and a narrow core set having a width less than a first width and comprising two adjacent narrow core sheets in face to face relationship each narrow core sheet having a top edge, a bottom edge, an outside edge connecting the top edge to the bottom edge and an inside edge connecting the top edge to the bottom edge, means for spacing the adjacent narrow core sheets, and fluid pervious fabric disposed between one said narrow core sheet and the means for spacing the adjacent narrow core sheets; wherein the wide and narrow core sheets are in substantially parallel arrangement, the outside edge of the said wide core sheet sheets extends beyond the outside edge of the narrow core sheets and the wide core set and narrow core set are secured to each other.
