Water sub-metering & AI leak detection

Asset protection for modern buildings.

Ten years of production metering, billing and remote shut-off — plus an AI leak-detection layer now in development with the University of Waterloo. Every drop accounted for, before it becomes a claim.

Corporation's deductible exposure per incident$50K–$100K
Time a slow leak can run undetected overnightHours
Ontario's Condominium Act (s.105) lets a corporation pass its insurance deductible back to the unit where a loss originates — one undetected leak can cost an owner tens of thousands of dollars.
The problem

Water damage doesn't ask permission.

Most buildings find out about a leak from the damage, not the meter. By the time it's visible, it has already run for hours through units, floors and shared infrastructure.

Real incident, managed portfolio

A 499-unit high-rise, one overnight leak

A slow 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 — triggering the corporation's full insurance deductible.

  • Water is among the top causes of condo claims

    Among the most common and costly sources of property insurance claims in Canadian multi-residential buildings.

  • The deductible follows the unit

    Under Ontario's Condominium Act, corporations can recover their insurance deductible from the unit where a loss originates — often $50,000 to $100,000.

  • Detection buys time no one else gives you

    A metering layer that already knows what normal flow looks like is the difference between a shut valve and a claim.

The approach

Measure. Protect. Steward.

Three layers, built in the order that actually protects a building — metering and billing first, remote control next, prediction on top.

Metering & transparent billing

Unit-level water metering with a flat monthly rate — no fee buried in the bill to recover a developer commission. Ten years in continuous production across the managed portfolio. Contact us for rates →

In production — 10 years

Remote shut-off

Building operators can isolate a unit's water supply remotely the moment a problem is confirmed — turning a multi-hour leak into a contained, minutes-long event.

Proven — years in operation

AI leak detection

A predictive layer trained to recognize abnormal flow patterns and flag a likely leak before it floods a floor — in active R&D under a funded research partnership with the University of Waterloo.

Technology

Built with a research partner, not a stock model.

University of Waterloo
Funded research partnership, in progress

Our AI leak-detection layer is being developed through a Mitacs Accelerate partnership with the University of Waterloo — a funded academic research collaboration, not a repurposed off-the-shelf model. The goal: recognize the flow signature of a developing leak early enough to act on it, not just log it after the fact.

  • Ten years of real flow data

    The model is trained against a decade of production metering history from real occupied buildings, not synthetic data.

  • Detection feeds a control that already exists

    A flagged anomaly can trigger the remote shut-off capability already proven in the field — detection and response, not detection alone.

  • Regulated, registered operator

    Onyx Energy Inc. is an Ontario corporation with a decade of Measurement Canada–registered metering operations behind it.
