Arizona's Complete Home Water Budget & Conservation Tool

Water conservation and real dollar savings, in one place.

More Than Irrigation Software

Your complete property water management tool.

Irrigation is 50–70% of a home's total water use — and it's the biggest lever for savings. But this platform goes beyond irrigation schedules. It connects your actual meter readings to your utility's billing structure, tracks your total household usage month over month, and gives you the checks and balances to know whether your bill is right, your system is working, and your water program is as efficient as it can be.

📊
Monthly Usage Trending

Log meter readings over time. Watch seasonal patterns, spot unusual spikes, and track whether your conservation efforts are working — month by month, year over year.

🧾
Bill Verification & Checks

Compare your utility bill to your logged meter readings. The system explains any difference in plain English — so you always know whether your bill is correct and understand exactly how you were charged.

🔄
Irrigation as the Starting Point

Irrigation drives your bill — it's the largest variable and the biggest opportunity for savings. Start there, quantify the cost, build a smarter schedule, and let the rest of the platform keep you accountable over time.

Why Irrigation Matters Most

Irrigation is your home's biggest water use — and the key to conservation.

In Arizona's desert climate, irrigation runs 6–8 months of the year and accounts for 50–70% of a typical home's total water consumption. It's the only variable large enough to push your monthly bill into a more expensive utility tier — or keep it out.

Water conservation has never been more urgent in Arizona. Rates are rising across the state — Gilbert alone saw a 50% increase in 2024 and another 25% in 2025. Managing your irrigation program is the single most impactful thing a homeowner can do for both their water bill and the water supply.

MyWaterBudget gives you the complete picture — from what each zone actually flows, to what your full home uses each month, to what your utility is billing you — so every water decision you make is based on real data.

🌵 Water Conservation in Arizona

Every gallon saved through smarter irrigation is a gallon returned to Arizona's strained water supply. ET-optimized scheduling alone reduces overwatering by 20–35% in most residential systems — without impacting plant health. That's conservation that also saves money.

Why This Matters

Water conservation in Arizona isn't optional anymore.

Arizona faces long-term water supply challenges, rising utility rates, and a desert climate that demands more from every drop. The homeowners who understand their water use are the ones who control their costs — and contribute to the solution. MyWaterBudget is built on the belief that every homeowner deserves access to the same water intelligence that professionals use every day.

18 years in irrigation contracting.
Built by someone who lived this problem.

I'm Robert Kemp. I founded and ran Water Wise Sprinkler Repair in Queen Creek, Arizona for 18 years before selling it in 2025. In that time I audited thousands of residential irrigation systems across the East Valley — and watched homeowners overpay on their water bills month after month because they had no way to measure what their system was actually using.

The science in this tool — ET calculations, precipitation rate formulas, tier analysis, leak detection — is the same methodology professional irrigation contractors use. I built MyWaterBudget to give homeowners the ability to calculate the true cost of their water use — because water conservation has never mattered more, and this is how I continue my passion for the green industry through software that makes a real impact.
