MyWaterBudget helps Arizona homeowners audit their irrigation systems, calculate real seasonal costs, and stay in a lower utility billing tier — backed by the same science used by professional landscape contractors.
$49/year · 14-day free trial · Works with SRP & EPCOR
No new equipment. No plumber visit. Just your water meter and about 20 minutes.
Run your irrigation overnight, then enter your meter's start and end readings. We calculate your actual flow in gallons, GPM per zone, and precipitation rate — the numbers your irrigation timer actually needs.
Meter Audit ToolTell us your plants, zone sizes, and soil type. We pull real evapotranspiration data and calculate an ET-optimized runtime for every zone, every month of the irrigation season.
ET Schedule BuilderConnect your address to your utility's rate structure. See exactly where you sit, how much water keeps you in a lower tier, and what the dollar difference is over the year. Stop overpaying by accident.
Tier Savings CalculatorBuilt on the same principles used by professional irrigation contractors — simplified for homeowners.
Overnight audit window isolates irrigation from indoor usage. Calculates actual GPM per zone and precipitation rate in inches per hour — no additional equipment required.
Evapotranspiration-based runtimes adjust for heat, plant type, distribution uniformity, and soil type. Water exactly what your yard needs — nothing more, nothing less.
Loaded with SRP and EPCOR rate structures. Shows your current tier position, what it costs to slip into the next tier, and your projected seasonal and annual cost.
Nine plant categories with professional crop coefficients. Add multiple zones, mix plant types, and get blended water needs that account for your actual landscape — not a generic estimate.
Project your water cost over any period — one month, one season, or full year. See the exact dollar impact of changing your program before you make the change.
Calculated runtimes translated into step-by-step programming instructions for your specific controller type — so your schedule actually gets set correctly.
Indoor water use is relatively fixed. Your irrigation program is the only variable large enough to push your monthly bill into the next tier — or keep it out.
Most homeowners have no idea how much water their sprinklers use per week. Without that number, you can't manage your tier position — you're just hoping the bill comes in lower.
MyWaterBudget gives you the actual numbers, connected to your actual rate structure — so you can make real decisions before the billing cycle closes.
