Origins of British reservoir safety legislation 1850–1930

Abstract

One hundred years ago in 1925, there were two dam failures with significant loss of life, and following these disasters, the 1930 Reservoirs (Safety Provisions) Act was enacted. Catastrophic failures in the nineteenth century had produced demands for government action but legislation had been much delayed by changes of government at critical times and by concerns about inadvertently reducing the legal liability of reservoir owners. Also, there was a marked lack of enthusiasm within the civil engineering profession for a government inspectorate. The key feature of the 1930 Act was that reservoir owners were required to appoint qualified civil engineers to inspect their reservoirs and, following such inspections, to implement measures required in the interests of safety. Post-1930 legislation, which it is intended will be the subject of a further paper, has done much to enhance public safety but the fundamental importance of independent qualified civil engineers has not diminished.
