Water Cost Calculator

Four quick questions and we'll show you the math — what your lawn actually costs to water, and what a smart Hydrawise controller saves on top.

Your property

Numbers update as you choose.

Pick the city your water bill comes from.
Look at your controller — it's the count of zone numbers it cycles through. Most homes have 4–10 zones. Don't know? Pick the closest guess.

Expected yearly cost of brown patches, dead branches, replants — gone with smart watering & alerts
  • Leak & flow alerts. Hydrawise pings your phone the moment a head shears off or a line ruptures — before the water bill gets ugly.
  • Even watering, no dry weeks. Generic timers run a fixed schedule whether plants need it or not. Smart watering keeps grass and shrubs through July heat instead of replacing them in August.
  • Tree & mature-plant insurance. A single mature tree replacement runs $1,200–$3,500 installed. One drought-stressed loss erases a decade of any "savings" math.
