Objective Reduce potable water used for irrigation and design a system that more closely matches the natural water usage at the site prior to development.
PS 2a Using indigenous plants reduces and in some cases eliminates the need for irrigation and using strong chemical fertilizers that can drain off into local water supplies. These plants celebrate, enhance, and highlight the city’s geographical location. If irrigation is required there are new irrigation technologies that include smart controllers that measure real time weather conditions and soil conditions for each type of plant. WE valves, spray misters and drip irrigation systems are effective in reducing water use.
A third way to reduce water is to combine a water reuse system with one of the new water efficient irrigation systems. This system will collect water that would usually Water supply for irrigation systems is not required to meet drinking water standards. Therefore, other systems discharge to the sewer or stormwater system and reuses can meet irrigation water demands. The overall demand the water for the facility irrigation system.
Benefit
from the domestic water system can then be reduced. Limitations Irrigation water demands may differ from reuse water availability and storage tanks and pumps may be needed. Water filtration systems add front end costs and maintenance costs. Background Reducing water usage for irrigation includes planting drought tolerant vegetation, installing water efficient irrigation systems, and/or incorporating water reuse supply systems. The LEED reference guide and EPA WaterSense material show alternative designs for irrigation systems.
