Abstract/Contents

Abstract: Non-potable water reuse is a crucial element in water sustainability. Particularly in the arid west, landscape irrigation can account for 50-70% of domestic water use during the summer months, and turfgrass accounts for a large fraction of irrigation. Traditional timed irrigation sprinkler systems do not account for actual soil moisture or for periods of wet weather. This leads to a waste of limited resources, where water may evaporate or run off before the grass can take in that water. Reclaimed water may have higher salt concentrations so it is traditionally not used to irrigate turfgrass, because turfgrass is sensitive to salinity and traditional irrigation systems lack salinity control. We are therefore creating a smart sensor irrigation system that will use sensors to measure soil moisture and salinity, as well as irrigation water salinity. This information will be wirelessly communicated to a computer, where an algorithm will determine whether to irrigate or not, based on a given grass’s moisture and salinity tolerance, and wirelessly actuate irrigation.
