A commercial zone where the pipework is sound and the loss is still large. Water that reaches a customer and is never billed follows the demand curve instead of running all night, which is why two zones can lose the same share and need entirely different work.

Spindle load and utilisation. Mainly useful when quoting.

Cut flowers under glass. Temperature, humidity, CO2 and vent position. One bad afternoon costs a shipment.

District meter. Night flow is the number that matters. Whatever is still moving at three in the morning is leaking.

Thirty seven degrees, tight tolerance. A short excursion overnight invalidates a week of work and you would never know.

Monitoring at the board. We had equipment failing and nobody could say why. Turned out to be sags, not the equipment.

18 kWp teaching array. Students can see where the losses go instead of taking my word for it.

22 kW drive on line two. The vibration trend is the entire reason it is monitored.

Small server room on a precision unit. Honestly this is here so I know how much headroom is left in the hottest week of the year.

Frozen container, minus eighteen the whole way. The log is the only thing that survives the journey.

Borehole feeding a 24,000 litre tank. Motor current is what tells me when it is starting to pull air.

Sat beside a busy road. Mornings are worse than I expected. Still air holds everything in until the sun gets up.

Dewatering the pit. If this stops, work stops, so it gets watched properly rather than checked on.

Walk-in behind the kitchen. Door openings turn out to be most of the load, which surprised me.

Compressed air costs us more than lighting and heating together. This is where I prove it to people.

Frost watch through the season. One night is all it takes.

Feed pump on the boiler. It threw a bearing in March and took the boiler down with it. Now it is watched.

A zone on ageing pipework, metered on its inlet against the volume billed within it. Physical leakage runs at the same rate all night, so where the loss is water in the ground rather than water unbilled, the minimum night flow says so plainly.

Incoming supply for the whole building. Tenants ask what happened. Now I can tell them.

Air handler on the third floor. Half of this is settling arguments about whether it is actually running.

One multi-deck on the chilled aisle. I am trying to work out whether the shrinkage is the case or the staff.

Main cold store, product for export. Since we started logging door time the arguments stopped.

One residential zone of a distribution network, metered on its single inlet, with the volume billed inside the zone alongside it. The gap between the two is non-revenue water, and splitting a network into zones is what turns one town-wide loss figure into somewhere to send a crew.
