8. Why Detect Leaks?
“Throughout the world, water resources continue to be spoiled, wasted and degraded. The consequences for humanity are grave”
Ban Ki Moon United Nations Secretary-General December 2007

9. Strategy for Water Leakage Management
The process of measuring flows of water in the network to establish how much is being lost and in which areas, includes establishing DMA’s, Flow Measurement and Data Logging
Localisation - identifying potential leak areas within the water network
Correlation – pinpointing a leak location to within a few centimetres
Confirmation - using acoustic microphones to verify the leak position
Customer Side – identifying leaks on the customer’s side of the meter
Reducing pressure to save water, minimise leakage,
extend asset life and reduce burst frequency

31. Why use Data Loggers? To gather data on network performance
To plan network expansion, pressure zones, DMA’s
To create network models
To ensure regulatory compliance
To measure leakage
To verify performance of Pressure Reducing Valves (PRV)

32. Why use Data Loggers?
Data collected from the logger shows that when the flow of water is low during the night, the water pressure increases. This feeds leaks and increases water lost through leakage.
In this example, HWM provided the equipment needed to regulate the pressure automatically, thereby making instant savings in water consumption.

35. Flow Zones provide valuable data to assess leakage

36. Question: How Big should your DMA be
Question: How Big should your DMA be? Do you need a DMA or larger flow measurement?
DMA concept
Creating DMA’s is expensive and time consuming – but gives valuable data
Insertion flow meters and modern data loggers make it much easier
Modern leak localisation can be used within or independent of DMA’s

37. Localise
Leak Detection
Solutions

38. Leak Localisation – Step Testing
Step Testing is an alternative approach to Noise Logging and works at low pressure and on plastic pipes
It works by continually measuring the flow of water into a DMA as valves are shut off in sequence.
Testing usually takes place during the night when water consumption is at its lowest so that shutting off the supply causes minimum disruption.
The areas of the pipeline showing unexpected water losses can then be identified and investigated.

39. Leak Localisation – Step Testing
MAST (Mobile Advanced Step Tester) is a radio based system which gives the operator immediate notification of flow change at the receiver as a valve is operated.
This allows potential leak areas to be quickly identified and quantified, avoiding the need to complete a full step test for later comparison with logged data.
The MAST system comprises two instruments:
Data logger with high power radio transmitter
Portable flow indicator/recorder with integral radio receiver
The Original MAST
MAST has recently been extensively redesigned to be more portable and user friendly. The new system (MAST II) also features improved radio telemetry.
The New MAST II

40. Leak Localisation – Noise Logging used in a DMA set-up or independently
Loggers detect noise created by leaks.
They are easily deployed on valves using
magnets and can be placed permanently
or moved from site to site. Using them
causes no interruption to water supply.

50. Beijing Olympics 2008
Three Permalog patrollers and 3,500 Permalogs were recently installed in Beijing’s municipal water distribution system to safeguard its water supply during the Olympics and beyond.
The Beijing Water Group originally purchased a set of 60 Palmer’s Permalogs in With the increasing demand of water supply and the approaching of Beijing Olympics 2008, the Group decided to improve its urban water network leakage detection system by purchasing more Permalogs.

91. Typical pilot adjusting screw
How Does A PRV Work?
Why Control ?
When adjusting the pilot, screw in and the PRV increases pressure on the outlet, by venting water from the PRV top chamber
When adjusting the pilot, screw out and the PRV decreases pressure on the outlet, by filling the PRV top chamber with water
Water in the top chamber then pushes
the PRV seat down and releases the
seat upwards when water is vented

Leakage in the Thames Valley at its lowest for ten years and is comparable to other water companies in England and Wales.
Our challenge is greatest in London, where over a third of our mains are over 150 years old
We began in 2002 a long term programme of mains replacement in London – the only truly sustainable way to bring down leakage.
Replacing mains is expensive and disruptive. The complexity and scale of the work is unmatched by any other water company.
This is a part of our wider water resources plan for the future when demand is expected to increase and our supply resources will change
