Colorado property owners are facing a new era of accountability when it comes to water use. Between rising utility costs, recurring droughts, and state laws like HB25-1090, transparency in billing isn't optional — it's essential. Submetering has become the clear path forward for communities that want to protect their bottom line while promoting fair, accurate water billing for every resident.
And when it comes to implementing a submetering solution built for Colorado, SimpleSUB stands apart.
SimpleSUB was founded and is headquartered in Colorado, which means we understand the unique challenges of our state's properties and climate. From mountain-town HOAs and Denver apartment buildings to sprawling mobile home parks on the plains, we've seen it all. Our team knows how to work with local utilities like Denver Water, Colorado Springs Utilities, and Fort Collins Utilities, and we're familiar with the rebate and efficiency programs each one offers.
Cold winters? We've designed our meters to perform reliably through freezing temperatures. Complex property layouts? Our cellular, clamp-on technology installs in minutes with no pipe cutting or trenching. And when you need help, our U.S.-based support team — right here in Colorado — is ready to assist.
Colorado's HB25-1090 law was designed to protect residents from deceptive utility pricing. It requires landlords and billing providers to deliver transparent, verifiable water usage data. SimpleSUB's system does exactly that. Each meter records daily consumption for every unit and automatically sends encrypted data to our secure cloud dashboard. Property owners can see usage trends, identify leaks, and ensure every invoice reflects real consumption — not estimates or allocations.
By automating this level of accuracy, SimpleSUB helps properties stay fully compliant and dramatically reduces resident disputes over water bills.
Many companies advertise "wireless" systems, but they often depend on property-wide Wi-Fi or repeaters that require power, maintenance, and troubleshooting. SimpleSUB's technology works differently. Each meter connects directly to the cellular network, sending data straight to the cloud — no gateways, bridges, or internet setup required.
That means:
This simplicity not only saves time and installation costs but also ensures continuous operation even in remote or high-altitude locations where Wi-Fi coverage can be spotty.
SimpleSUB is more than just hardware. We offer complete billing solutions that handle everything from usage tracking to monthly resident invoices. You can choose a self-service model or let us manage the entire billing process, including collections and reporting. Either way, we make submetering effortless — so you can focus on running your property, not managing spreadsheets.
Hundreds of units across the state already rely on SimpleSUB for accurate, compliant, and stress-free water billing. If you manage an apartment complex, HOA, or mobile home park in Colorado, there's no easier or more reliable way to submeter water.

SimpleSUB Compliance: All SimpleSUB Water meters exceed Colorado's accuracy requirements and include built-in reporting to help property managers maintain full compliance with state regulations.
