New Hampshire property owners are facing rising utility costs, aging infrastructure, and growing pressure to use water wisely. Between long winters, freeze–thaw cycles, and busy summer seasons, you cannot 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.
New Hampshire has a bit of everything, from historic mill buildings and classic New England downtowns to newer garden-style apartments and townhome communities. Properties in Manchester, Nashua, and Concord look very different from ski-area condos in the White Mountains or manufactured home communities in smaller towns, and plumbing setups vary just as much. SimpleSUB is designed to work across that variety.
Cold, snowy winters and big temperature swings are a fact of life here. Our meters are built to perform reliably through freezing conditions, and the over-the-pipe design helps you measure on lines that would be difficult or expensive to retrofit with inline meters, especially in older buildings with limited access.
New Hampshire properties also come with their own quirks, like mixed-use buildings, lakefront communities with outbuildings, long service lines, well houses, and scattered utility rooms. 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:
This setup reduces complexity, cuts down on potential failure points, and helps keep everything running smoothly, even in hillside properties, wooded lots, or lake communities where Wi-Fi coverage can be inconsistent.
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 are 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 are 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 New Hampshire already rely on submetering for accurate water tracking, faster leak detection, and easier day-to-day water management. Whether you manage an apartment building in Manchester, a lakeside HOA, a mobile home community in a rural town, or a mixed-use building in a historic downtown, SimpleSUB gives you a simple, reliable way to submeter water in New Hampshire.
