If your property already has submeters installed and your water bill still isn't where it should be, the meters probably aren't the problem. The billing company running them is.
A submeter is a tool, and like any tool, what it produces depends entirely on who's using it and how. With nearly 30 years of experience in the submetering industry, we've seen the same pattern repeat across properties of every size: a system that should be driving water consumption down sits largely idle because the billing company behind it is doing the bare minimum. The meters tick along, the bills go out, and the data that could be catching leaks and flagging waste just sits there untouched.
What follows covers what a billing company doing the bare minimum actually looks like, what active submetering management produces instead, and what separates a vendor who lowers your water bill from one who just sends a monthly invoice.
What Most Submetering Companies Actually Do
The standard operating model for most utility billing companies is straightforward: read the meters, generate pre-bills, send invoices, and answer the phone when tenants call to complain. The data the system collects every day, usage patterns, consumption spikes, units showing zero flow, units running at five times their normal rate, sits in the platform and nobody looks at it.
Property managers who've worked with these vendors know the experience well. Emails go unanswered for days. Reports that should be standard are impossible to get. Response times on service requests stretch into weeks or months. When a lease turns over and a unit sits vacant, the water keeps running and nobody notices until the master bill arrives.
The frustration is rarely with submetering as a concept. It's with billing companies that treat a sophisticated utility management system like a billing printer.
What the Data in Your System Is Actually Telling You
A properly managed submetering system generates actionable data every single day, and an active billing company uses it to stay ahead of problems rather than reacting to them after the fact.
High consumption alerts flag units that are using dramatically more water than their history suggests. A unit that has averaged 3,000 gallons a month suddenly showing 40,000 is almost certainly running a toilet. According to the U.S. Environmental Protection Agency, a single running toilet can waste up to 200 gallons per day. A two-bathroom unit with two running toilets can waste up to 12,000 gallons in a month. Left undetected, that waste runs up the master water bill for months before anyone files a complaint.
Zero usage alerts are equally important. A unit showing no water consumption when it's occupied isn't conserving. It means a transmitter has failed and the meter has gone dark. Without that alert, the unit gets estimated or skipped, the billing data is wrong, and the catch-up bill that eventually arrives generates a tenant dispute.
A proactive submetering company doesn't wait for tenants to call. It runs consumption reports, flags anomalies, notifies the property manager before the problem compounds, and gives the property access to its own data so the management team can see what's happening in real time. Most billing companies never do any of this.
What Submetering Water Savings Actually Look Like
The savings potential from a well-managed submetering system isn't theoretical. We covered a real example on the Think About It Show, our industry podcast, that illustrates what active management produces on a small property.
When Integrity Meter installed a new system and began actively managing the property, monthly water consumption was running at 496,000 gallons. Within three months, that number dropped to 96,000 gallons. Three months is typically the time it takes for tenants to adjust behavior, for leaks to be identified and repaired, and for usage to normalize.
That's an 80.6% reduction in water consumption on a 17-unit property.
The culprits were exactly what a proactive system would have caught quickly: running toilets, dripping faucets, and tenants who had no reason to report issues because they weren't paying the water bill. Once Integrity Meter had real-time visibility into unit-level usage, the problems surfaced immediately. Once they were addressed, the savings followed.
This isn't an outlier. Pacific Northwest National Laboratory, properties that shift from flat-rate or allocated water billing to individual metering see water consumption reductions to approximately 15 percent or more. Active system management pushes that number higher.
We've also worked with a 350-unit condo community that was spending $1.2 million annually on water through allocated billing. A conservative 20% savings from submetering and active management would return over $240,000 per year. At that rate, the system pays for itself in a matter of years.
Why Your Bill Stays High With the Wrong Vendor
The 80.6% reduction on that 17-unit property didn't happen because the meters were exceptional. It happened because someone was actually using them, which the previous vendor wasn't doing.
This is the pattern we see repeatedly: billing companies that partner with a meter manufacturer, pair it with an AMR system, and run the same one-size-fits-all setup on every property regardless of what the data is showing. Nobody is certified in the equipment. Nobody is running health reports. Nobody is telling the property that their system has been degrading for two years.
We've fielded calls from property managers whose billing company had no idea what to do with new transmitter IDs after a replacement. The billing software hadn't been updated, the AMR system wasn't configured correctly, and the meters were physically in place and reading accurately but sending data nowhere. The property was paying for a service that wasn't being performed.
Staying with a vendor like that doesn't just mean poor service. It means absorbing water costs that a properly managed system would have caught and recovered. Every month a running toilet goes undetected is another month of water waste landing on the master bill.
What We Do Differently at Integrity Meter
We give you your own data
The data your submetering system collects belongs to your property. At Integrity Meter, we don't hoard it. We give every property direct access to the platform so you can see usage in real time, run your own reports, and monitor what's happening between billing cycles. Properties that have been denied this access by previous vendors are consistently surprised by how straightforward it is when a vendor actually provides it.
We run proactive reports
A high-low consumption report, showing which units are using far more or far less water than expected, is not a premium feature. It's a basic function of any properly managed submetering system. Most vendors never send one. At Integrity Meter, it's standard practice from the first billing cycle. One new property that received their first high-low report from us told us they had been asking their previous vendor for something like it for years and could never get it.
We catch leaks before they compound
Submetering is built for leak detection. That's not a secondary benefit. It's one of the primary functions of unit-level water monitoring. When we're actively watching consumption data, we flag a running toilet within days. A vendor who only looks at meter data at billing time lets it run for 30 days or longer before anyone catches it. The difference in water cost between those two approaches compounds quickly.
We communicate before problems escalate
When a transmitter fails and a unit goes dark, we notify the property manager immediately and provide an estimated reading based on historical usage so the tenant isn't billed incorrectly. When a repair creates a catch-up billing situation, we communicate with the tenant in advance so the bill isn't a surprise. These aren't extraordinary gestures. They're the baseline of professional service in this industry, and they're rare enough that properties consistently describe them as unlike anything they've experienced before.
We know the equipment
Not all submetering companies are equipment specialists. Many partner with a single manufacturer and run the same configuration on every property regardless of fit. At Integrity Meter Solutions, we hold NextCentury Certified Installer credentials and work with equipment from multiple exclusive partners including Next Meters, Master Meter, Eltek, and Inovonics, because different properties have different requirements. Knowing which system works best in which application is the difference between a setup that performs and one that technically exists.
How to Make the Switch Without Losing Your Mind
The biggest barrier to switching submetering vendors isn't finding a better company. It's the fear that the transition will be disruptive. In most cases, it's more manageable than it looks.
Check your current contract status first. Know whether it auto-renews, what the termination notice period is, and whether there's an early termination fee. Some contracts only require 30 to 60 days notice.
Don't cancel until you've signed with a new vendor. Have the new agreement in place before you notify the outgoing company.
Expect the outgoing vendor to be uncooperative. Not every company hands over transmitter IDs, meter reads, and system configuration data willingly. Your new vendor should be prepared to conduct an audit if needed.
Give the transition 90 days. It takes about three billing cycles to get accurate data, normalize consumption, identify issues, and get the property running cleanly. Bumps in the first month are normal. A good vendor holds your hand through them.
Our submeter installation service and submeter maintenance service are both designed to support properties coming from a previous vendor, whether that means a full system replacement, repairs to an existing system, or simply taking over billing and management of a system that's already in place.
Frequently Asked Questions
How much can submetering actually reduce my water bill?
It depends on the property, but the Pacific Northwest National Laboratory documents water consumption reductions of approximately 15 percent or more when properties switch from flat-rate or allocated billing to individual metering. Properties with significant undetected leaks such as running toilets, dripping faucets, and supply line failures can see much larger reductions once those issues are identified and addressed. One 17-unit property managed by Integrity Meter reduced its monthly water consumption by 80.6 percent within three months of a new system installation.
Why is my water bill still high if I already have submeters?
In most cases, the issue isn't the meters. It's how actively they're being managed. Submeters collect data continuously, but if your billing company isn't monitoring that data for high usage alerts, running regular reports, and notifying you of anomalies, leaks and waste go undetected. A running toilet can waste up to 40,000 gallons a month per unit. If your vendor only looks at meter data at billing time, that waste can run for 30 days or longer before anyone catches it.
What reports should my submetering company be providing?
At minimum, a high-low consumption report each billing cycle showing which units are using significantly more or less than expected. A system health report at least quarterly showing whether all meters and transmitters are communicating correctly. Leak alerts in real time when a unit's usage spikes beyond normal parameters. And direct platform access so you can see usage data yourself without waiting for a report to be sent.
How long does it take to switch submetering companies?
The contract and onboarding process can move quickly, but plan for 90 days before the system is fully normalized. That window covers equipment installation or audit if needed, account setup, the first billing cycle on accurate data, and the initial period where tenant consumption adjusts in response to usage-based billing. A good vendor communicates clearly throughout that process so nothing catches the property off guard.
What if my current submetering system is outdated?
Switching vendors is often a good time to evaluate whether the system itself needs updating. If your meters are approaching or past their expected lifespan, or if your AMR system doesn't support real-time data, a replacement may make more sense than a repair. Our site survey service assesses your current system's condition and gives you a clear picture of what you're working with before any decisions are made.
Does switching submetering companies disrupt billing for tenants?
A well-managed transition minimizes disruption. The new vendor should communicate the change to residents, explain how billing will work going forward, and have accurate data in place before the first billing cycle goes out. It typically takes one to two cycles to get everything running cleanly. A reputable vendor will estimate accounts conservatively during the transition period and flag any catch-up billing situations before they hit a tenant's invoice.
