Water sub-metering & AI leak detection
Every drop accounted for.
Aqua Meter AI
Leak detection built on real research.
Developed in partnership with the University of Waterloo.
We measure water usage, providing clients with accurate invoicing and seamless, secure payment processing, all combined with best-in-class leak detection. At Aqua Meter AI, every drop counts, especially the ones that you cannot see.
Water. The Quiet Destructor
Leaks are often active in the background, undetected, quietly destructive, until they're caught by the damage, or by a shocking water bill months later. By the time anyone sees it, the water has already made its way through units, floors and shared spaces.

Water Insurance Claims on the Rise
More than 40% of home insurance claims at Allstate Canada from 2021 to 2025 were for water damage.*
Not every leak comes from a storm. Many start inside, with a burst pipe, a worn out supply line or a toilet that keeps running. Aqua Meter watches water use in units and common areas, so leaks get caught early, before they cause damage.

Living in a Condo, Who Pays for Water Leaks?
In Ontario, Section 105 of the Condominium Act lets a condo corporation charge a unit owner for water damage that started in their unit.
Condo corporation deductibles can easily reach tens of thousands of dollars, and when a leak starts in your unit, that bill can end up with you. Most owners don't realize their own insurance may only cover part of it, or none at all. That leaves people paying out of pocket or borrowing money to cover damage they never saw coming.

Active Leak, Real-Time Shut-Off
A leak alert comes in while you're away. You can't get home, no one can check, and a plumber can't get in.
With Aqua Meter AI, you can shut off your water with a tap on your phone, stopping the leak before it does real damage.
Real buildings. Measured results.
Two real buildings: what one leak cost, and what metering saved. Neither is a projection.
A 499-unit high-rise, one overnight leak
A slow supply-line leak began overnight and ran undetected for hours before it was found the next morning. By then it had travelled through 13 units across 10 floors, causing $352,000 in damage and triggering the corporation's full insurance deductible.
Village on the Green
About 108 townhomes on per-suite water sub-metering. On an annual water bill of $167,000, a 21% reduction returns $35,070 a year to the corporation, roughly $27 per unit every month, once residents could see their own consumption.
See what water is really costing you.
Put in your unit count, your water bill and your claim history. The model shows the exposure your building carries today, what early detection avoids, and what metering saves, with your numbers, not ours.
The Region has paused new development over water supply.
Thousands of residential and commercial units are stalled in planning as a result.
The Region's own diagnosis
Aging infrastructure, rising demand and, critically, the "plateauing of conservation efforts." The binding constraint on new housing is demand outrunning supply, and the conservation gains that used to help have stalled.
Metering is the fast lever
A 21% reduction in metered demand, the kind already measured at Village on the Green, frees servicing capacity without waiting years for new infrastructure. Cape Town avoided "Day Zero" the same way: by making consumption visible.
When it comes to water. We Measure It. Bill It. Save It.
Accurate metering. Fair, transparent billing. Built with an AI layer. All of it serves one goal, protecting the water we all depend on. While saving you money.
Why Water Matters to Us
Water shortages aren't a distant problem. They're happening in our own backyard. Waterloo Region has run up against the limits of its water supply. Alberta communities have faced drought and emergency restrictions. Cape Town came within weeks of turning off its taps. Every litre we save today protects the supply we all share tomorrow.
Our Process
Water consumption.
For water abnormalities.
Confirm water loss with client.
Shut-off water. Minimize damage.
Meter Every Unit and Water Source
Individual water metering for any type of property: apartments, condominiums and commercial plazas. Every unit pays for exactly what it uses, and every unit can be monitored for leaks. Hotels benefit too. Leak detection cuts one of their largest operating costs and improves overall profitability.
Quick, Easy Installation
We install in occupied buildings with minimal disruption. Residents and tenants carry on as normal while we work. Installation also allows other work to be combined, such as installing water shut-offs.
Find Hidden Leaks
Detailed water reporting catches the hidden losses: running toilets, dripping taps and pinhole leaks behind walls. A single running toilet can waste thousands of litres a month. Don't let your money go down the drain.
Shut Off at the Source
When a leak is detected, the water can be shut off at the source before it floods a suite, damages the units below or turns into an insurance claim. Less water wasted and less damage to repair.
Developer Credits. Not with Aqua Meter. Ever.
No Kickbacks.
Here's something the sub-metering industry doesn't want you to know: business isn't always won on merit. Sometimes it's bought.
Many providers offer developers and property owners large upfront payments, usually called "installation credits." So who really pays for them? The end user: the homeowner, the restaurant owner, the tenant. Those credits get built into administrative fees, which pushes up costs for people who are already watching every dollar.
We won't buy your business. We'll earn it.
A real research partnership, not a marketing claim.
Through a research partnership with the University of Waterloo, supported by Mitacs Accelerate, we're building something new in water management.
The work is led by Dr. Albert Jiang, a Banting Postdoctoral Fellow. The Banting is one of Canada's most competitive federal postdoctoral awards. Albert holds a Ph.D. in water resources engineering, is a licensed Professional Engineer, and has a background in systems design and mechatronics.
Our models learn from real metering data in occupied buildings, not synthetic data. They recognize normal water patterns, flag anything unusual and trigger tiered alerts based on how serious the issue is.
Why this Partnership Matters
-
Monitoring in Real Time
Our detection layer learns what normal flow looks like for each suite and watches it continuously. A leak shows up as it starts, not on next month's bill. It also catches phantom leaks, the quiet, always-running losses that never announce themselves and are where most wasted water goes.
When residents can see their own water use, consumption drops by 18 to 22%. That's money back in their pockets every month, but the bigger win is millions of litres of water that never go to waste. Alerts escalate along a set path, from occupant to property manager to management company, so someone acts while it's still a simple repair, not an insurance claim.
-
We Don't Just Sound the Alarm. We Stop the Water.
Most leak detection ends with a warning. A sensor beeps in an empty suite. A phone call goes to voicemail. A text sits unread while the homeowner is at work, on vacation or asleep. Meanwhile the water keeps running until a busy property manager checks their messages or someone finally gets home.
Our system doesn't wait for someone to answer. When it detects a serious leak, it shuts off the water at the source, so the damage stops right away, and people have time to catch up and respond.
The people behind Aqua Meter.
Eric Reiner
Eric has spent more than 20 years in Ontario real estate and development, and has been with Coldwell Banker Peter Benninger Realty since 2002. He was named Coldwell Banker's #1 Sales Professional for Ontario Commercial four years running, from 2010 to 2013.
Eric doesn't just sell buildings. He builds them. As both owner and general contractor, he has developed multiple residential buildings from the ground up, managing everything from design and financing to construction and day-to-day operations. He knows firsthand what goes on behind the walls, where things go wrong and what it costs when they do.
Eric's connection to water goes back further. He studied hydrogeology at the University of Waterloo, the science of how water moves beneath our feet, long before Aqua Meter existed. That background shapes how he sees every building, as a system where water is one of the most valuable and most overlooked resources.
Aqua Meter brings it all together. Eric understands buildings as a developer, a builder and an owner, and he believes conserving water is as much a responsibility as a business opportunity.
Angel-Marie Reiner
Angel-Marie built Onyx Condo Management from the ground up into a growing management company trusted by condo boards and property owners. Her work earned a $100,000 federal grant, recognition as a "Woman to Watch" and a "Small Business of the Year" award.
Running a management company puts her where the problems happen. She has handled the late-night leak calls, the water damage that spreads to the suites below, the insurance claims and the frustrated residents asking why their bill went up. She knows that water loss isn't just a number on a utility bill. It means stress for owners, costs for corporations and strain on the boards she serves.
As the face of Aqua Meter, Angel-Marie leads client relationships and sales.
