Claim 1

An underground fluid exchange system for control of delivery to and removal from the turf area of a playing field comprising: a) a playing field having a selected soil profile comprising a combination turf and topsoil turf segment, a porous soil segment and an impervious soil segment; b) fluid exchange apparatus positioned underground in the porous soil segment for controlling the transfer of fluids between the solid profile and a reservoir comprising soil-embedded porous conduit comprising a continuous filter wall for selectively receiving filtered drainage fluid and filtered subsurface irrigation; c) reservoir means for receiving and storing all fluids introduced to the soil profile; e) manifold means for connecting the porous conduit to said reservoir f) pump means for transferring fluid form reservoir means to soil profile of turf b) an encapsulation means for enclosing the soil profile positioned underground beneath the playing field; g) control means with sensing means for controlling transfer of chemical laden water between a turf and soil profile and a containment reservoir wherein said fluid exchange system restricts any "leaching" or movement of chemicals into ground waters and directs all irrigation waters, fertilizer and pesticides into a holding tank for recycling.
