GWC's friendly and professional leakage survey technicians are trained to the highest standards and are backed by industry-recognised water qualifications. Furthermore, we have invested in the latest leak detection technology ensuring you get reliable, accurate results, every time.
Our main areas of expertise are:
Leak detection survey
- Leak detection surveys
- Trunk main surveys
- Customer leakage surveys
- Commercial leakage surveys
- Flow monitoring and analysis
When you contact us with a suspected leak within
a given area or DMA our technicians will conduct
a full and thorough survey of the problem area.
This will include checks on the integrity of the
zone or area and a brief assessment of commercial
consumption. We will then survey all mains and
fittings with a leak noise correlator and traditional
sounding techniques. We also use additional equipment
such as ground microphones, hydrophones and gas
injection when required. The exact method of survey
and equipment used will depend largely on the
pipe material, availability of fittings and the
pressure in the distribution system.
Trunk mains survey
Trunk mains surveys are a vital part of any leakage control programme both in terms of water loss and the ability to supply and control the distribution network. However, the methods required for trunk mains leakage vary from our standard survey due to the distances and availability of fittings. We have investigated the various methods of survey and equipment in order to provide the most accurate auditable results. Upon completion of your survey, you will be given a detailed report including electronic files of all correlations completed, details of all leaks located, GPS and digital images of the surveyed fittings. All surveys are designed to provide a full audit trail for all works completed and are therefore, suitable for inclusion in your company's annual returns.
