HWM’s pressure controller helps Bournemouth Water reduce leakage and bursts

Posted: Tuesday 8th November 2016

The Pegasus+ pressure control system from multi-utility monitoring and telemetry specialist HWM has helped Bournemouth Water (BW) reduce leakage by 1 Ml/d and achieve short-duration burst reductions of 54 per cent.

The pressure controller is responding directly to data recorded by HWM loggers at critical points (CPs) in the network and adjusting the delivery pressure. Phase one of the project has been completed, resulting in 17 new Pegasus+ installations. Phase two, currently undergoing commissioning and delivering predicted savings, will see another 62 units installed.

There were several reasons why BW chose HWM as the supplier for the project:

Having traditionally adopted pressure management measures only in areas with existing high pressure, BW decided to use pressure management to reduce leakage across parts of its distribution network.

BW’s models showed that extensive pressure management could take place at DMA level and predicted potential savings and benefits that included: leakage reduction; overall volume savings leading to reduced production costs; reduced short-duration bursts; and extended asset life for the ageing network.
