Abingdon Reservoir
Vale of White Horse, United Kingdom
The White Horse Reservoir (previously known as the South East Strategic Reservoir Option, or SESRO, and later the Abingdon Reservoir) is a long-term proposal for fresh water storage for the Home Counties. To be located south-west of Abingdon, Oxfordshire, in the mid-west of the Thames Basin, it is intended to help support water supply provision in the south-east of England. The proposals have been developed primarily by Thames Water, along with Southern Water and Affinity Water, as the reservoir is intended to serve all three companies' customers.
