About Our Underwater Engineering Company
Since the early 80s the Water Services Group have been at
the forefront of long-distance internal water pipe surveys, inspection and testing
and were the first company to develop and operate a Water Pipe Inspection
We design, build and operate bespoke P I Vs to carry out remotely
operated vehicle surveys (ROV) on a broad array of inspection and
testing services from within pipes, where any other form of inspection
or testing would be impossible to achieve.
We have inspected, tested, mapped, measured and surveyed pipes,
tunnels, aqueducts, culverts, sewer pipes and long-sea outfalls
varying in diameter between 350mm - 6m, over distances in excess
of 24km and in flow rates varying between static and 2.3 metres
In September 2014 we designed and built the Worlds first
multi-camera PIV to survey a 21km x 2.5m diameter water transfer
tunnel accessed via 50-90m deep access shafts. This was to provide
a full circumferential view of the pipe and to accurately measure
deformation on profiling sonar.
This level of Client support is only made possible by the combination
