If you are an irrigation or water nerd like us, you've heard of the two major types of water efficiency certifications: WaterSmart and SWAT. Here's a quick rundown of important similarities and differences you should know about. First, a bit of historical context:

SWAT History SWAT, or Smart Water Application Technology, was created in 2002 by the Irrigation Association (IA). The IA is a coalition of irrigation industry representatives that seeks to promote efficient water use in landscape related products. It is a private organization that certifies water efficient products like irrigation controllers and rain sensors based on published protocols. To become SWAT certified, a product must go through a stringent testing procedure, and the manufacturer must pay for the testing. When SWAT was created, many municipalities used it as a basis for offering rebates on efficient products.

WaterSense History
The Environmental Protection Agency (EPA) created WaterSense in 2006 as the water equivalent of EnergyStar, a voluntary program to promote the efficient use of water. The WaterSense certification is a broader certification program than SWAT as it covers non-irrigation products like toilets and shower heads, for example. Like SWAT, many municipalities offer rebates on water bills for WaterSense certified products. The Differences

Timing. In broad terms, SWAT came first, and WaterSense adopted SWAT's certification protocols with a few minor changes. Most of these changes reflect a slight emphasis on measuring water savings in western states versus the eastern region of the United States.

Minimum runtimes. WaterSense added minimum run times as western states can go long stretches without any rain, versus in the east where it's assumed there will be intermittent rainfall.
