The program is known as SWAT (for Smart Water Application Technology). It?EUR??,,????'?????<

SWAT began in 2002 when leaders from the irrigation industry and water agencies met for the first time at the annual International Irrigation Show. Since then, test protocols for climate-based controllers were developed by the Center for Irrigation Technology on behalf of SWAT. CIT conducted controller tests on a virtual test plot designed to include a variety of zones with different irrigation requirements.

Climate-based controllers can use historic weather data, on-site sensors or a central weather station that transmits data to the controller.

Test results for products from ETwater, Irritrol, Toro and WeatherTRAK are posted at www.irrigation.org. From the home page, scroll over the Government Affairs tab, and then down to Industry Initiatives and over to SWAT then look for Performance Reports on the left menu bar.

The controller tests evaluate two basic criteria: adequacy and efficiency. Adequacy is whether the controller provides enough water for plant health, and efficiency is if the controller avoids over watering.

Product testing is voluntary and requires a $2,500 fee, paid by the manufacturer, to cover the costs of the tests. To submit a product for testing, contact the Center for Irrigation Technology, (559) 278-2066.
