Service Pipe Leakage
Leaks from services pipes account for a significant proportion of unaccounted for water in UK water distribution networks. This report covers various aspects of the subject looking principally at detection and location methods. A comprehensive decision chart has been developed to aid the user in selecting the most likely lowest cost repair solution. A prototype twin wall insertion probe has been developed which enables the precise location of a service pipe leak to be determined. The bulk of the report is dedicated to the experiments conducted using neural networks to attempt to characterise service pipe leaks. The aim was to use the acoustic signals given off by a leaking pipe to determine the location and size of the leak as well as the material from which the pipe was made. Whilst some results are promising there is a considerable way to go before the recognition software would be of any commercial value.

A supply pipe leakage estimate is required for regulatory reporting. However, a more detailed understanding of proportion of total leakage that is associated with supply pipes will also improve operational allocation of le... More...Price: £200 Add to basket
The natural rate of rise in leakage relates to the underlying rate at which leakage increases within a system. NRR is essential for determining the intensity of active leakage control that is required to maintain leakage at a... More...Price: £200 Add to basket
