Southern Water Leakage Detection
Southern Water Services Limited
RPS was commissioned by Southern Water Services (SWS) to manage and detect leaks across the distribution network, maintain PRV's as well as conducting trunk main surveys and data collection for leakage allowance analysis.
RPS supplied all required resources over a 5 year period to complete the leakage tasks and ensure that SWS met its regulatory leakage targets from 2005 to 2010.
RPS managed the leakage in 809 DMA containing 1 million properties and 12,000km of mains. RPS also completed bi-annual surveys on 1,700km of trunk mains, undertook over 8,000 meter reads for studies and maintained the 455 PRV.
Throughout the delivery of this contract, RPS provided many benefits to SWS and these included:
Over 46,000 leaks found pro-actively and 11,000 leaks re-actively over the 5 years and passed to the R&M contractor for repair. Equivalent to around 360 Ml/d.
The award winning partnership delivered the lowest leakage levels in the country in 2005/06 (drought) of 5.6 m3/km/d, and was recognised by industry bodies including Utility Week and SBWWI.
In addition to these benefits, RPS was able to support SWS in other activities, including Distribution Support and Standby, training of SWS staff in National Hygiene and Valve Ops, PRV optimisation and designs, leakage reporting software support, leakage allowance analysis and June Return reporting.
