Improving the efficiency of in-ground irrigation systems can save water, reduce utility bills, and improve landscapes by avoiding over-watering. Big payoffs in water savings also result from careful plant choice, soil improvement, and changing how and when you water.

Properties served by water providers in the Saving Water Partnership can get financial assistance to install water-conservation upgrades to irrigation systems.
