A sports field has a stable, impermeable substrate, a water distributing layer provided over the substrate and an artificial turf layer over the water distributing layer. A bund defines a perimeter of the sports field and extends from the substrate to at least the height of the artificial turf layer. A drain channel having inlets at a height to communicate with the water distributing layer is provided such that water can flow from the water distributing layer into the drain channel and vice versa. As a result of this constructions, there is formed a containment, defined by the bund surrounding the field and by the substrate. Water can be held within the containment in the water distributing layer allowing for water attenuation and cooling of the sports field.

A golf course bunker drainage system has been developed that is a modular structure taking the form of a plurality of porous bunker paver blocks formed of material exhibiting vertical and horizontal infiltration rates at least the same as bunker sand. The plurality of porous bunker paver blocks is disposed as a boundary layer between a bunker subsoil bottom surface and overlying bunker sand, allowing rainwater to drain into the subsoil, with excess rainwater directed away from the bunker sand. The use of bunker paver blocks also maintains the integrity of the bunker shape and prevents movement of sand and other materials along steeply sloping bunker sidewalls.

Systems and methods for a ground water filtration system are described. The ground water filtration system includes paver blocks designed to facilitate liquid seepage between the paver blocks and to route the seepage to a preferred area. A filter may be utilized to remove undesired particulates in the seepage prior to routing. The ground water filtration system additionally provides at least one layer of stone to facilitate flow direction of the seepage. At least one geogrid fabric is also provided to further enhance ground water filtration.

A modular system for constructing an elevated pathway includes a first pathway segment comprising a first elevated platform portion; first edge supports to bare a load of the first elevated platform portion, wherein the first edge supports contact a ground surface and create a grade separation between the ground surface and a bottom side of the first elevated platform portion; and a first joint. The modular system also includes a second pathway segment comprising: a second elevated platform portion; second edge supports to bare a load of the second elevated platform portion, wherein the second edge supports contact the ground surface and create a grade separation between the ground surface and a bottom side of the second elevated platform portion; and a second joint to attach to the first joint to limit a motion of the second pathway segment relative to the first pathway segment.
