Missouri property owners are facing rising utility costs, aging infrastructure, and more pressure to manage water responsibly. Between hot, humid summers, stormy seasons, and cold winters, 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.
SimpleSUB understands how diverse Missouri properties really are. From Kansas City and St. Louis apartment communities to student housing in Columbia and Springfield, and from lake-area HOAs at the Lake of the Ozarks to mobile home parks and small-town multiplexes, plumbing layouts can look very different from one site to the next.
Missouri also deals with big weather swings. Hot summers, heavy rain, and winter freeze–thaw cycles can all put stress on plumbing systems. Our meters are designed to perform reliably through those conditions, and the over-the-pipe design helps you get measurement on lines that would be difficult or expensive to retrofit with inline meters.
Many Missouri properties have their own quirks, like older buildings with tight mechanical rooms, mixed-use spaces, long service runs between buildings, or scattered utility rooms around a campus-style layout. SimpleSUB’s cellular, clamp-on devices are built to handle these 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 Missouri’s cities, college towns, and rural 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
• Flexibility to expand coverage as you add more meters or bring new buildings online
This setup reduces complexity, cuts down on potential failure points, and helps keep everything running smoothly, even on spread-out properties where Wi-Fi coverage would be difficult or expensive to maintain.
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 do not 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 Missouri are turning to SimpleSUB for accurate water tracking, faster leak detection, and easier day-to-day water management. Whether you manage an apartment building in St. Louis, a lake-area HOA, a student community in Columbia, or a mobile home park in a small town, SimpleSUB gives you a simple, reliable way to submeter water in Missouri.
