A copy of the report of a research project conducted and presented by Owen Roberts and directed jointly by Dr Richard Coopey and Professor Aled Jones. The three main objectives of the project were to write a series of narrative histories of dam building and water supply in north east Wales from the 1880s to the present day, to equip future researchers with a guide to archives and collections pertaining to the Welsh water industry, and to establish within the University of Wales an internationally recognised centre for the study of water history.
