Water loss & leakage blog.
Practical articles on understanding, measuring and permanently reducing water loss in distribution networks and industrial plants. For the field side of the method, see the projects.
01How to tell if there is a water leak?
Eight signs of hidden loss in a drinking-water network and how it is confirmed.
02What is flow measurement?
Portable and permanent flow meters, choosing the measuring point, minimum night flow.
03What is pressure management?
The pressure–leak link, pressure managed areas (PMA) and PRV control.
04How is acoustic water leak detection done?
Step-by-step location with noise loggers, a ground microphone and a correlator.
05What is a DMA (District Metered Area)?
Splitting the network into measurable zones, minimum night flow and step testing.
06What is a step test?
Closing valves in steps at night and reading the flow drop to narrow the loss.
07What is a zero-pressure test?
Isolating a section and dropping pressure to zero to decide leak or no leak.
08What is hydraulic modelling?
A computer simulation of the network: input data, field calibration and scenarios.
09What is pipe locating?
Finding the route and depth of buried metal and plastic mains without excavation.
10What is network mapping and GIS?
Turning field data with GPS coordinates and attributes into a GIS layer.
11Leak repair and verification
Point confirmation, repair types, and verifying recovered loss with post-repair night flow.
12A roadmap for cutting water loss
The NRW / IWA framework and an eight-step programme for lasting loss reduction.
For your network
Let's measure the loss and pinpoint it.
In a short video call we can review the current situation and the method to apply.
