Modern golf courses are doing an excellent job of applying the exact amount of irrigation needed--no more, no less--to satisfy the demands of turfgrass. When there are periodic rainfalls of over 1/2", within hours, that beneficial water has percolated downward beyond the root depth and is lost. The soil, already near Field Capacity, cannot retain the rainfall.
With the Rain Trap System, we can catch and reservoir that rainfall. Now an additional 4.7 days' supply of water is safely stored within the root zone. The grounds superintendent can factor in this reserve supply through substantially reduced irrigation. For an average golf course, this translates into an annual savings of 60 million gallons of pumped water, the equivalent of the yearly needs of 545 households. These U.S. averages can go up or down depending upon local climate and soil conditions.
The patented Rain Trap System's civil engineering technique assures uniform embedment and low installation cost. Three corresponding pieces of specialized equipment complete the operation simultaneously. In a single process, the ground is excavated, the pre-split tires are precisely planted, the tires are covered, and the earth is compacted and ready for topsoil.
Research has concluded that the technology and engineering of the Rain Trap System is scientifically valid. To further determine the exact amount of water and fertilizer savings under various soil and climate conditions, on-going field tests of the the Rain Trap System are being administered by the Center for Irrigation Technology, California State University, Fresno. A bibliography of studies is avaliable upon request.
Golf courses use water--lots of it--to keep the turfgrass in top condition. This can be city water, well-pumped water or reclaimed effluent, but in any case, the cost of obtaining and pumping it is high. Without added construction costs, the passive Rain Trap System recycles otherwise wasted rainwater to substantially reduce pumped water costs. And, because the tires are planted well below ground, there is no water lost to evaporation.
