Illinois property owners are facing real pressure around water use. Rising utility costs, aging infrastructure, and a mix of historic and newer buildings mean 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.
Illinois properties range from dense urban buildings around Chicago and Evanston to quiet suburban communities, college-town rentals, and manufactured home communities in small towns and rural areas. Each comes with different plumbing layouts, common areas, and usage patterns, and SimpleSUB is built to adapt to all of them.
Older multifamily properties, brick walk-ups, and mixed-use buildings are especially common in Illinois. Many have limited access to main lines or crowded mechanical rooms. Our clamp-on meters mount on the outside of existing pipes, which helps you get measurement without cutting into lines or doing major renovations.
Illinois weather brings hot, humid summers and cold, snowy winters, often with big swings in temperature. SimpleSUB’s hardware is designed to perform reliably across these conditions, so you can monitor water use in basements, utility rooms, and outbuildings without worrying every time the weather shifts.
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:
This setup reduces complexity, cuts down on potential failure points, and helps keep everything running smoothly across a wide variety of Illinois properties.
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 shutting down entire sections of the building 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 can start small, prove the value, and then scale up as needed.
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 Illinois already rely on SimpleSUB for accurate water tracking, faster leak detection, and easier day-to-day water management. Whether you manage an apartment building in Chicago, a suburban HOA, a student-focused property in a college town, or a mobile home community in a smaller city or rural area, SimpleSUB gives you a simple, reliable way to submeter water in Illinois.
