The average age of UK reservoirs is 120 years old and this also generally applies to the associated valves and pipework which are critical to the safe operation of the dam. The failure of such equipment to operate properly – whether routinely, or in an emergency can have severe operational or safety consequences. CIRIA’s 1997 Guide: Valves, pipework and associated equipment in dams – guide to condition assessment
(R170) provides guidance on the topic (See Box).
The UK Reservoir Safety Advisory Group has identified the need for further research and guidance on the selection, operation, evaluation, repair, maintenance and replacement of gates and valves. CIRIA is co-ordinating the project to gather experience, feedback and case studies on this topic with a view to delivering a project that will update and extend its current guide.
| Summary of contents of R170
Fundamental components and the causes of failure.
Assessment stages including:
Options for Action and Implementation
- Locating valves and pipework
- Hazard and risk assessment
- Inspection techniques
- Evaluating exposure
We are pleased to announce that this project has started and that the research contractor is Arup
