A Second World War PLUTO (Pipeline Under The Ocean) pumping station is visible on aerial photographs of 1946 as extant buildings and structures to the north of Lade. Three buildings may have housed pumping stations, and two more provided staff quarters. The site also included a large cylindrical tower, possibly for fuel storage, and two very large irregularly-shaped pits. By the time of the next available vertical aerial photograph of 1959; the cylindrical tank had been removed, and the pits had been filled in. The buildings which housed the pumping stations and staff accommodation lie either side of Leonard Road, and are still in use as houses today. These features were mapped from aerial photographs as part of the South East RCZAS NMP project.
