I was interested to read the article about the building of water and gas infrastructure in the Victorian era (Chrimes Watch, NCE 7 December 2006).
Having been involved in the relining of Staines Reservoir's inlet mains in 2004, the photograph of a section now affectionately known as the 'trouser legs' was instantly recognisable.
During the recent renovation works we often marvelled at the magnitude of the task that original constructors had in building these mains, which are in fact made of half pipeshaped steel plates with joints riveted both longitudinally and circumferentially.
The fact that the joints have remained watertight and the mains are still in service are a testament to the skills of the pioneers that we would do well to emulate.
