CP402 - Impact of Valve Operations on Water Network Performance
The operation of valves within the water distribution system can lead to increased velocity and pressure. Such pressure transients can travel through the distribution system and affect performance and standards of service. It is believed that this is the cause of the short term deterioration in burst rate performance experienced in many mains rehabilitation and replacement projects.
WRc are running a collaborative Portfolio research project, to be completed over a period of 8 months, which will verify and quantify pressure transients in a range of distribution systems of varying material type and operating conditions, in order to fully understand the impact of valve operations on network performance. It will utilise field measurements, WRc test rig results and computer simulations to identify the areas of the network most at risk, and develop practical procedures to minimise network disruption from the operation of valves.
This work will provide water utilities with the ability to amend current practice at minimal cost and maximise benefits from mains replacement, mains rehabilitation and leak repairs. This will ultimately reduce costs associated with the detection and repair of leaks and improve customer service.
