Non-revenue water is not fixed by intuition. It is divided into districts and measured.
Drinking Water Networks & Leak Detection
Dividing a network into district metered areas with live flow and pressure, so losses are located rather than merely totalled.
The problem
Loss rates in many local networks exceed 30%. The figure is known at city level and unknown at street level - and nothing can be repaired that cannot be located.
How we solve it
We split the network into district metered areas of no more than 2,000 connections each, with a flow meter and a pressure sensor at every district inlet.
Minimum night flow is the indicator: between 02:00 and 04:00 nobody is supposed to be using anything much. Whatever passes the meter in that hour is leakage - measured, not estimated.
What it delivers
A repair priority list ordered by loss volume per district, instead of a random search campaign along the whole network.
What it includes
-
District metered areas
The network split into units whose inflow and outflow can be measured accurately.
-
Minimum night flow
What passes between 02:00 and 04:00 - the standard method for estimating leakage.
-
Live pressure
Pressure is monitored because excess pressure is a leading cause of repeat bursts.
What you receive
-
DMA design
The zoning map, isolation points and meters required.
-
Monthly loss report
Loss in cubic metres per district, ranked by priority.
