Interview: Pat McIntyre of ET Water Systems on More Efficient Irrigation

Irrigation accounts for about a third of water use in the United States.  Traditional irrigation control that uses sensors to detect soil moisture is expensive.   But we can leverage our extensive collection of weather data and knowledge of transpiration of plants and soil to create a lower cost system.  This video from the recent Going Green 2010 conference with Pat McIntyre, the CEO of ET Water Systems, profiles their irrigation control system that uses data, instead of sensors, to cut irrigation water usage by up to 50%.   Their irrigation controller communicates with the cloud, as in cloud computing, to retrieve weather data and execute an irrigation algorithm based on landscape characteristics.  The result is ROI in 2 years.  Conservation is important but not always easy to achieve.  But with conservation technology such ET Water Systems, there’s much less excuse for achieving the triple bottom line of conserving resources, lowering cost and preserving our quality of life.
