Patent attributes
A subsurface irrigation system for a sports field includes a substantially water impermeable layer, a compacted subgrade below the water impermeable layer, a plurality of water distribution boards positioned on top of the water impermeable layer, a porous layer overlaying the plurality of water distribution boards, and a sports field layer on top of the porous layer. The porous layer is configured to move water from the plurality of water distribution boards upwards to the sports field layer using capillary action to keep it damp. The sports field layer may be sand, dirt, clay, or a combination thereof. In addition, the system may include a water control basin in fluid communication with at least one water distribution board of the plurality of water distribution boards and configured to control the flow of water to the plurality of water distribution boards.
