As much as 60% of all household water consumption can go to outdoor uses. Irrigation systems should be designed not to waste potable water. A good system delivers water efficiently at the right time. Systems that distribute water indiscriminately, like lawn sprinklers, are inherently wasteful.

While lawn and garden work are tempting DIY projects, a certified pro can help you accomplish your water conservation goals more efficiently. At least they can help you make better choices when designing the system.

The Environmental Protection Agency has a national list of irrigation professionals who have completed a certification process through the EPA's WaterSense program.
