How much water will turf save you? This free artificial turf water savings calculator turns your lawn size and region into the gallons and dollars you stop pouring into the ground every year, with every number sourced below.
Calculate my savingsEnter the square footage of living lawn you'd convert and pick your area. We prefill the local water use and rate, tweak the rate to match your bill for an exact number.
Prefilled from your region. Find the real number on your water bill (often billed per HCF = 748 gallons). Enter it for an exact result.

lawn vs turfLawns drink more where it's hot and dry. Tap a state to load its numbers into the calculator. The desert Southwest and inland California lead the country for turf water savings.
Each state is shaded by how much supplemental water a lawn needs there in a year. Brighter green means a thirstier lawn, and bigger savings when you replace it with turf.
Use this in the calculatorTurf water savings come almost entirely from the irrigation a living lawn no longer needs. We estimate that irrigation from regional evapotranspiration, the water a lawn loses to heat and air over a year beyond what rain provides:
Artificial turf uses no scheduled irrigation, only the occasional rinse, which is negligible, so the lawn's requirement is the saving. The regional figures below are climate estimates; your own water bill is the exact input, which is why the rate is editable and defaults are conservative.
| Region | Lawn water (in/yr) | Default rate ($/1k gal) | Saved / yr, 1,000 sqft |

Sources and assumptions: supplemental irrigation figures derive from regional reference evapotranspiration (ETo) for cool and warm-season turfgrass, using California CIMIS data for the California regions, and EPA WaterSense outdoor-water guidance. The 0.623 gallons per square foot per inch conversion comes from the USGS figure of 27,154 gallons per inch over one acre. Default water rates are regional averages of residential commodity charges and vary widely by district and tier; drought and tiered pricing can push real savings higher. States are shaded by their main population centers, so if your climate differs (St. George, UT or El Paso, TX run closer to Desert Southwest) pick your region in the calculator. Figures are estimates for planning, not a guarantee, and cover outdoor irrigation only. Last updated October 2026.
How conservative is this? The Southern Nevada Water Authority projects 825,000 gallons a year saved for an average 15,000 sqft lawn conversion, about 55 gallons per square foot. This calculator uses about 39 gallons per square foot for the Desert Southwest, so real savings there may run higher than shown.
<a href="https://mightyturfinc.com/water-savings-calculator/">Artificial turf water savings calculator</a>Straight answers on how much water artificial turf saves, why, and how the numbers change by region.
It depends on how thirsty your lawn is, which is mostly about climate. A 1,000 sqft lawn saves roughly 36,000 gallons a year in the High Desert, about 32,000 in the Inland Empire, and closer to 15,000 in the humid Southeast. The calculator above gives your number from your square footage, region, and water rate.
No scheduled irrigation, which is where lawn water goes. Turf gets an occasional rinse for dust or pet areas, but that is a rounding error next to the tens of thousands of gallons a living lawn needs each year. The savings in the calculator are the irrigation a lawn no longer requires.
Near the top of the country, behind only the desert Southwest. Hot, dry inland California means a lawn there needs 50 to 60 inches of supplemental water a year. On a typical 1,500 sqft front yard in the High Desert that is well over 50,000 gallons annually, and at local water rates often 400 dollars or more a year off the bill.
Gallons saved equals your lawn area times the region's yearly supplemental water in inches times 0.623 gallons per square foot per inch. Dollars saved is gallons divided by 1,000 times your water rate. The regional water figures come from evapotranspiration data and EPA WaterSense guidance. The full method and a per-region table are in the section above.
They add to it. Many Western water agencies pay a per-square-foot rebate to remove living grass, on top of the water you stop buying. This calculator counts only the water savings, so a turf-removal or Cash-for-Grass rebate is money on top of the numbers you see here.
It sidesteps them. Watering-day limits, allotments, and drought surcharges are built around irrigation. Turf has none, so it stays green through restrictions that turn real lawns brown, with no penalty and no schedule to track.
