A long running series started in 1899 with the 'Water supply of Sussex from underground sources'. Over a period of 39 years twenty-eight memoirs were published mostly under the title: 'Wells and springs of…'. They were based on a county basis. The last county based water memoir was published in 1938 was the last revision of 'The water supply of the County of London'. This was notable as it was the first to include location diagrams for the sites of all recorded wells. This series was superceded by one-inch sheet based reports, first in the Wartime Pamphlets and later in the 1960s by the Well Catalogue Series Water Supply Papers of the Geological Survey of Great Britain for England and Wales and for Scotland.
