Water Leak Detection
 Waterlink
provides water leak detection and location
services throughout the UK for commercial
and industrial customers.
Waterlink is able to undertake water
leak detection and location (i.e. non-visible,
below ground losses) using water industry
standard practice including pipe tracing,
step testing, transfer testing, top
sounding and real time multi-point
correlation.
This activity is undertaken
using only Water Company trained and
employed personnel.
Pipe tracing is undertaken
using Radiodetection RD500, Kat and
Genny and flexitrace locators. These
use a variety of techniques to detect
and map underground pipework, in particular
the generation of a radio signal that
is transmitted through the pipework
which is then picked up by the detector
enabling a very accurate identification
of the location of underground asset.
Pipework buried at depths of up to
3 meters can be detected using these
methods.
Step testing involves
the isolation of discrete zones, then
the monitoring of the variation of
consumption within these thus enabling
the particular zone(s) with the leak
to be identified and isolated.
Transfer testing through
the revision of supply arrangements,
changing zonal areas in conjunction
with step testing. This activity aids
the process of leak location by positional
iteration. This is particularly useful
where the zones cannot be easily separated.
Top sounding – standard
industry techniques using sounding
and listening equipment. This ranges
from the simplest technique that involves
the use of a sounding stick pressed
to the engineer’s ear through
to more sophisticated electronic detection
systems using both noise and heat.
Correlation – Primayer
eureka, Radcom soundsens and Spectroscan
aquacor. Each device has specific abilities
and applications with site conditions,
infrastructure and location determining
the appropriateness of use.
