Water Monitoring: The Overlooked Utility

Everyone focuses on electricity, but water waste can be just as costly — and harder to detect. Here's why more of our customers are adding water to their monitoring.

Electricity gets most of the attention in utility management, and for good reason — it's typically the largest cost and the most visible. But for manufacturing sites, food processing facilities, irrigated land, and multi-tenanted buildings, water is increasingly where the conversation is going. Here's why.

Water leaks are uniquely difficult to detect

An electrical fault usually makes itself known — something stops working, a circuit breaker trips, or consumption spikes visibly. Water leaks often don't have equivalent signals. A slow leak in a buried pipe, a valve that isn't fully closing, or an irrigation system with a cracked head can run for months with no obvious sign at the surface. The only reliable detection method is continuous flow monitoring with anomaly alerting.

The cost profile is different from electricity

Water is cheaper per unit than electricity, which is part of why it gets less attention. But the compounding effect of a continuous leak is significant — a 1 litre-per-minute leak running undetected for a year is about 526,000 litres. At typical commercial water rates, that's between $800 and $2,000 depending on your region and tier. For larger leaks, the numbers escalate quickly. At sites with cooling towers, process water, or large irrigation systems, water costs can represent a meaningful fraction of total utility spend.

Overnight flow is the key metric

The most useful single indicator for water monitoring is overnight flow. During hours when a site is unoccupied and no water should be consumed, any measured flow is a signal. It could be a slow-running toilet, an irrigation system activating outside its schedule, or a process circuit that isn't closing properly. Conexie's water monitoring uses exactly this logic: set an expected overnight baseline (typically zero), and alert when measured flow exceeds it.

Integration with electricity monitoring

For sites that already have electricity monitoring in place, adding water monitoring uses the same infrastructure. The data sits on the same platform, the same dashboards show both utilities, and alerts are managed in the same place. The incremental cost of adding water meters to an existing Conexie installation is low. For sites that are already paying for monitoring software, the marginal cost is essentially just the hardware and installation.

Where it makes the most sense

Not every site needs water monitoring. For office buildings where water consumption is predictable and mostly tied to occupancy, the ROI case is harder to make. The strongest cases are: irrigated land or grounds where manual checks are impractical, sites with cooling towers or evaporative systems, food and beverage or manufacturing facilities where process water is a significant input, and multi-tenanted properties where sub-metering for tenant billing applies to water as well as electricity. If you're already monitoring electricity on one of these sites, it's worth running the numbers on water.
