Visited the Bolton underground reservoir with BB
Bolton Council bought the New Hey site in the early 1960’s and turned it into an underground reservoir in 1963.
With its thick concrete walls (4ft 8 at the bottom), it was designed to store up to 12 million litres of water in case of a water shortage but it was never used and United Utilities, which now manages the North Wests water supply, sold it to Harwood Homes for £21,000.
The reservoir is roughly 40m wide, 40m long and 5.4m high. and from what the owner said the concrete is almost 5ft thick at the bottom. plans are for the underground reservoir to be transformed into a £2 million luxury house under innovative plans drawn up by a Bolton developer. who will create a five-bedroom luxury home with a swimming pool.
