2.4 million litres, two leaks, $21,000: what we never saw coming

In September 2022, the water meter at our Port Stanley short-term rental recorded 2,413 cubic metres of consumption in a single month. That’s 2.4 million litres — roughly an Olympic swimming pool — through one house, at about 80,000 litres a day.

We didn’t see any of it. The leak was underground. No puddle, no sound, no damp smell, nothing on a walkthrough. The first sign anything was wrong was the bill: $14,811.25 for one month of water and wastewater.

We’re contractors — 18 years of residential construction. We know how houses fail. And we still found out from a utility bill, weeks after the fact, because there is no human sense that detects an underground leak. The house looked perfect the entire time.

Then it happened again

In June 2023, the same property: a second undetected leak, 1.1 million litres this time, about $7,000 in charges. Two leaks at one property, more than $21,000 combined.

One leak is bad luck. Two is a lesson. A plumber visit fixes a leak; it doesn’t fix the category of problem, which is that some failures are invisible until the meter or the bill tells on them — and a monthly bill is the slowest possible alarm.

What the bills taught us

Three things, in order of how much they cost us to learn:

First, flow is the truth. The meter knew on day one. Everything else — visual inspection, walkthroughs, the neighbour with a key — sampled the wrong evidence. Continuous flow measurement on the water main would have surfaced both leaks within hours, not weeks.

Second, vacancy is a multiplier. The property sat empty between bookings. An occupied house self-monitors by accident: someone eventually notices the water bill, the sound, the pressure drop. An empty house volunteers nothing.

Third, detection without response is just earlier bad news. Knowing about a leak at hour one only matters if someone assesses it, decides, and gets a valve closed or a plumber out. The full chain is detection, assessment, action — and that chain became the company.

We publish the redacted bills on our story page, because “trust us, it was expensive” isn’t our style. The consumption chart on the September 2022 bill — eleven flat months and one spike — is the most honest piece of marketing we will ever produce.

The Port Stanley house is now HavenIQ’s first monitored property. The building that taught us the lesson will never surprise us again.
