The Greater London and Surrey (County and London Borough Boundaries) (No. 2) Order 1993
This Order makes two boundary changes. One is to the boundary between the county of Surrey (Spelthorne district) and Greater London (Richmond upon Thames). Parts of Stain Hill Reservoirs, lying between Staines Road East and Lower Hampton Road are transferred to Greater London, and to Richmond, uniting the Reservoirs and the area surrounding them in that county and borough. The area of land transferred is approximately 21 hectares, and it is uninhabited.
