Valves, pipework and associated equipment in dams - guide to condition assessment

This publication provides guidance for dam owners, engineers, specialist contractors and others responsible for the maintenance, operation and safety of dams. It gives practical advice on recognising problems that can arise from the deterioration of valves, pipework and associated equipment. The guide sets out a logical step-by-step process for condition assessment, involving location, inspection, monitoring, evaluation of results and remedial measures. It describes how the hazard and risk posed by each element of a dam's pipework system are influenced by its structural and service condition. While the content is concerned with existing reservoirs and is not intended as a design guide for new works, much of the information is relevant to new construction as well.
