Consultant Pell Frischmann is set to undertake a second phase of surveying work for South West Water (SWW) using a new elecrostatic probe detection system following successful early trials.
The system is designed to detect leaks in the sewerage system and was originally developed in the USA.
It does not rely on visual recording of infiltration, but instead uses electrostatic probes to detect leaks within the pipelines in a flooded condition. The firm believes it significantly reduces time taken to survey long lengths of sewers and ultimately costs.
In November 2012, Pell Frischmann undertook the first UK demonstration of the sewer detection system for client SWW.
“As part of SWW Partnering Alliance, we have assessed this emerging technology and believe it offers significant benefits to pinpoint infiltration and overcome difficulties experienced with conventional CCTV techniques in low lying coastal catchments where saline infiltration presents specific challenges,” said SWW engineering director Graham Murphy.
