Arizona property owners are facing real pressure on water. Between long, hot summers, ongoing drought conditions, and rising utility costs, you can’t afford to guess where your water is going. Submetering gives you clear, unit-level insight so you can control costs, reduce waste, and keep your communities running smoothly.
Arizona properties are as varied as its landscapes. From Phoenix and Tucson apartment communities to HOAs in growing suburbs, mobile home parks, and student housing in college towns, every site has its own plumbing layout and challenges. Desert master-planned communities, older infill properties, and mixed-use buildings all need flexible ways to track water.
Extreme heat, dry air, and heavy irrigation demand are a fact of life across much of the state. In places like Phoenix, Mesa, and the wider Valley, outdoor usage and cooling needs can add up quickly. In northern and higher elevation areas like Flagstaff and mountain communities, you also see cooler seasons and some freeze–thaw. SimpleSUB meters are designed to perform reliably across these conditions, and the over-the-pipe design helps you measure lines that would be difficult or expensive to retrofit with inline meters.
Arizona properties often include long service runs, detached garages, scattered utility rooms, and extensive common-area or landscape irrigation. SimpleSUB’s cellular, clamp-on devices are built to handle those realities with flexible placement and minimal disruption to your existing plumbing.
A lot of “wireless” systems still depend on on-site Wi-Fi, repeaters, or custom network gear that someone has to set up and maintain. SimpleSUB works differently.
Each meter connects directly to the cellular network and sends data straight to the cloud, with no gateways, bridges, or property-wide Wi-Fi required.
That means:
• Reliable performance in dense metro areas, suburbs, and smaller Arizona communities
• No on-site IT infrastructure or repeaters to manage
• Daily readings that make it easier to monitor usage and spot unusual patterns
• Secure, long-term data storage so you can track trends over time
• Better visibility into both domestic use and irrigation lines
This setup reduces complexity, cuts down on potential failure points, and helps keep everything running smoothly, even on spread-out desert properties where Wi-Fi can be inconsistent or impractical.
SimpleSUB is designed so your maintenance team, plumber, or preferred contractor can get up and running quickly. The clamp-on hardware mounts on the outside of the pipe, so you’re not cutting into lines or doing major construction just to start measuring.
Once the meters are in place, the web app is straightforward and easy to navigate. You can see usage by unit, review historical trends, and add more meters over time as you expand coverage across the property. You don’t have to overhaul your entire system on day one to start getting value.
SimpleSUB hardware is designed and built in the United States, with a focus on reliability and long-term performance. You’re working with equipment built for real-world conditions, not just lab tests.
When questions come up, you can reach a US-based support team that understands both the product and the realities of managing properties like yours. You get practical help, clear answers, and a partner that speaks your language.
Properties across Arizona already rely on SimpleSUB for accurate water tracking, faster leak detection, and easier day-to-day water management. Whether you manage a multifamily community in the Phoenix metro area, an HOA in Tucson, or a mobile home park or mixed-use property in a smaller Arizona town, SimpleSUB gives you a simple, reliable way to submeter water in Arizona.
