Case in point, Thames Water has been trying to build a reservoir in Oxfordshire since 2006[1], but has only met resistance by the local planning authority and environmental campaigners (the two often working in concert when it comes to NIMBYism due to various statutory obligations placed on local authorities.)

A few months ago the government reclassified the project as Nationally Significant Infrastructure Project to allow Thames Water to to take the proposal out of the hands of the local authority, potentially allowing the project to go ahead. [2]

If it goes ahead as planned it will be the second largest reservoir in the UK.
