Calculation of Potential Water Savings

Conversion of 1,000 square feet of turf grass to drought tolerant, low water use plants is estimated to reduce the water requirement by 77 percent. The reduction in plant water needs is lowered from approximately 37,200 gallons per year to 8,680 gallons per year per 1,000 square feet.

Replacing 1,000 square feet of turf grass would save approximately 28,520 gallons of water. The annual estimated water savings for a typical 500 square-foot lawn conversion project in Marina is $53.38, and a conversion project of 1,000 square feet would save $106.76 annually.
