Watch: See the area to be flooded by new reservoir
Plans for a reservoir in the Oxfordshire countryside would be "absolutely devastating" for a business located on the land, its owner has said.
A consultation on Thames Water's South East Strategic Reservoir Option, near Abingdon, is due to end this week.
It would supply 15 million people in the south east of England including customers of Affinity Water and Southern Water.
Hal Colliver said it would be "impossible" to relocate his air maintenance and training company, which is located within the area earmarked for the reservoir.
Thames Water has insisted the project, costing up to £7.5bn, is a "vital piece of national water infrastructure".
