help save water because they? heads
Landscape Irrigation The art and management of applying water to
landscape in a manner to encourage growth of
plant material and support water conservation
Irrigation sensors (Measure rain, wind, soil moisture, and freeze)
that save water and eliminate liability issues
concerning ice related accidents during freeing
weather
Pressure Regulation Device Devices which eliminate misting or fogging at the
sprinkler heads, thus achieving better uniformity
and saving water
Hydrozoning The practice of zoning an irrigation system based
on similar plant material with similar watering
reguirements due to environmental and or
geographic influences including, but not limited
