Case study · Water sub-metering

Village on the Green

When residents could see and were billed for their own water, the community used about a fifth less of it. Measured, per suite.

The situation

One bill, no accountability

Like most townhome communities of its era, Village on the Green paid for water as a single building-level expense. Residents had no visibility into their own use and no reason to change it: a running tap, a silent toilet leak, or a long shower cost the same to the household either way, because the bill was shared.

For the condominium corporation, that meant a rising, lumpy water expense it could neither attribute nor control, and no early signal when something was quietly leaking.

What we did

Meter every suite. Bill fairly. Watch for leaks.

We retrofitted per-suite water sub-metering across the community, installed in occupied homes, with the equipment cost financed over the contract term rather than charged up front. Each household now sees and pays for its own water, and the same meter data feeds continuous monitoring that flags abnormal flow before it becomes a claim.

No developer credits sit behind the fee, so there is no recovery premium baked into what residents pay. The billing is transparent and proportionate: you pay for what you use.

"The meter didn't just measure the water. It changed how people used it."
The result

A 21% lower water bill

Once each household was accountable for its own consumption, water use across the community fell by 21%. That is a measured reduction, not a projection, and it is the single number we are most confident about, because metering makes it directly observable.

The savings come from ordinary behaviour change plus the early detection of small, silent losses that a building-level bill would never reveal.

What it can mean for a building

From percentage to dollars

At Village on the Green the numbers are real, not illustrative. The community was spending about $167,000 a year on water. A 21% reduction returns $35,070 a year to the corporation, across roughly 108 homes, about $27 per unit every month. That is before counting the catastrophic-leak exposure that early detection helps avoid.

How to read this

The 21% reduction at Village on the Green is a measured result for this community. Your own figures depend on your building's rates, occupancy and consumption. It is not a guarantee of identical results. A no-charge water savings audit produces the real numbers for your property, and the interactive insurance model lets you test the catastrophic-leak side of the equation.
