Maryland property owners are operating in a new era of water accountability. Between rising utility costs, heavier strain on local systems, and changing weather patterns, 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.
Maryland brings together a wide mix of property types in a relatively small state. From historic rowhomes and walk-up apartments in Baltimore to garden-style communities in the suburbs around D.C., plus townhome communities and HOAs across the I-95 corridor, every building comes with its own plumbing realities.
Along the Chesapeake Bay and coastal areas, properties often deal with humidity, storms, and aging infrastructure. Inland, you may see older multifamily conversions, mobile home communities, and newer mixed-use developments side by side. SimpleSUB’s over-the-pipe design makes it easier to submeter in all of these environments, including buildings where cutting into lines for inline meters would be complicated or disruptive.
Maryland’s seasons bring hot, humid summers, heavy rains, and cold snaps in the winter. Our meters are designed for real-world conditions and are built to perform reliably through temperature swings, damp mechanical rooms, and complex plumbing layouts.
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, whether your property is in downtown Baltimore, a suburban community outside Rockville, or a mobile home park on the Eastern Shore.
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 can start with a single building or section of a community and grow from there without overhauling your entire system on day one.
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.
From urban apartment buildings in Baltimore and Silver Spring to HOAs and townhome communities in the suburbs, as well as mobile home and manufactured housing communities across the state, Maryland properties rely on clear insight into water use. SimpleSUB gives you a simple, reliable way to submeter water in Maryland so you can manage consumption, reduce surprises, and keep your communities running smoothly.
