Denver property owners face some of Colorado's highest water and sewer costs, with Denver Water rates increasing each year. Combined with Colorado's HB25-1090 — which requires submetering for qualifying multifamily properties — the pressure to adopt a cost-effective solution has never been higher.
SimpleSUB is headquartered in Wheat Ridge, just minutes from Denver. We know Denver Water's rate structure, the city's building stock, and what it takes to install submeters in everything from Capitol Hill apartments to Aurora HOAs.
Denver's multifamily housing stock ranges from century-old Victorian conversions to modern high-rises — and SimpleSUB works on all of them. Our clamp-on submeters attach to copper, PEX, PVC, and CPVC pipes without cutting or modification. No plumber. No permit. No tenant disruption.
As a Colorado-based company, we understand Denver Water's billing structure and can help you translate submetered usage data into accurate, dispute-free tenant bills.
Colorado's House Bill 25-1090 requires qualifying multifamily property owners to install submeters and provide usage-based billing to tenants. SimpleSUB submeters exceed Colorado's accuracy requirements (±5% or better), and the SimpleSUB Dashboard generates the itemized billing statements the law requires.
Don't wait — HB25-1090 has enforcement timelines, and SimpleSUB is the fastest path to compliance for Denver property owners.
Many Denver properties — especially older multifamily buildings — don't have reliable WiFi coverage throughout. SimpleSUB's built-in cellular connects directly to the cloud with no gateways, bridges, or IT infrastructure needed.
SimpleSUB serves properties across the Denver metro — from Capitol Hill apartments to Castle Rock HOAs. Our local team provides hands-on installation support from people who know Colorado's property market.
For a typical Denver apartment building, SimpleSUB submeters run under $400 per unit with a $6/month subscription. At Denver Water rates, most property owners recover the hardware cost within 3–6 months of billing tenants for actual usage. After that, water cost recovery is pure NOI improvement.

SimpleSUB submeters are designed and supported by a U.S.-based team headquartered right here in Colorado. When you call or email, you reach someone who knows Denver’s property market — not an overseas support queue.
Every SimpleSUB submeter comes with a 5-year warranty and lifetime data retention, included in your monthly subscription.
