Talybont Reservoir – innovations in pipework replacement, London

Watch this event

Please note that the BDS AGM will take place at 18.00 followed by the evening lecture at 18.30.

The presentation will cover the application of modern technology and innovative approaches which successfully led to the full replacement of the supply and scour pipework and valves at Talybont Reservoir in South Wales, formed by a 30m high embankment dam. It will explain how the use of siphons were able to maintain supply and compensation water throughout the duration of the construction during one of the driest summers on record in the UK.

Isolation of the mid-level drawoff required unusual underwater excavation and engineering. Advanced underwater surveys and the application of robotics enabled the isolation of the low-level drawoff and scour pipework and valves. The presentation will include the challenges encountered in developing and implementing the strategies which successfully facilitated safe replacement of the drawoff works without impacting the security of water supply.

Admission free | Teas available from 17.30pm.

This meeting will also be streamed live on the internet.
