Find the losses while they’re still small
Water and gas leaving the network without reaching a customer is revenue gone and, in gas, a safety matter. Continuous measurement makes losses visible as they develop, instead of at the end of the month.
Night flow, and what pressure says about it.
In a zone with stable demand, the minimum overnight flow is the clearest signal a network gives. A rising floor over several nights, or pressure that sags where it used to hold, points at a loss that is growing.
The hours when legitimate demand is closest to zero.
A floor that climbs across nights, not one bad reading.
Pressure that sags where it used to hold corroborates the flow.
Every district judged against its own history, not a common threshold.
A typical configuration.
In CLog.
Night flow, night after night, per zone. When the floor rises, the zone is worth investigating; when it drops after a repair, you can show what the repair recovered.
CLog narrows the window — when the loss started, how fast it is growing, how it behaves against pressure — so the survey team walks the right length of main on the right night.
The same record that justified the dig shows what the repair recovered.
