How to plan sub-metering, close a water balance, run night flow tests, price loss from your own tariff and confirm each fix at the meter, in the order a facility team works. It also covers real and apparent losses and how each shows in meter data. See reduce water loss.
Facility and plant managers who want leaks found before the bill, sustainability leads who need water savings that stand up in a report, and multi-site operators choosing where to start. It suits anyone responsible for a water bill they cannot explain.
Not to start. A metered main and a few branch meters are enough to begin locating loss, and existing pulse, Modbus, M-Bus or camera-read meters can usually be brought online. The playbook shows where an extra meter pays for itself first. See water meters.
It compares actual use with a degree-day baseline instead of last month, so a hot week, a full house or an event does not look like a leak. Night flow tests on quiet hours add a second check that weather barely affects. See weather-normalized baselining.
