United Utilities (UU) has submitted plans for a £15 million scheme to create a new underground water storage reservoir.
The proposals are aimed at keeping reliable water supplies on tap for the south Stockport and High Peak areas.
The communities that would be served by the new service reservoir include: Disley; New Mills; Mellor; Rowarth; Birch Vale; Whaley Bridge and Furness Vale.
Kevin Davies, UU project manager, said: “This will be a major investment for the High Peak area and it’s vital to help safeguard water supplies for around 40,000 people.”
The proposed new structure, at Jackson’s Edge Road, Disley, would store up to 18 million litres of treated water – enough to fill more than eight Olympic-sized swimming pools or 200,000 baths.
Kevin said: “The existing tank at Jackson’s Edge, known as a service reservoir, is 100 years old. It has served us well, but it is now coming to the end of its life.”
Engineers are planning to build the new structure in two phases to ensure water supplies are not interrupted.
If the planning application is approved, work is expected to start in early 2014 and take three years to complete.
Kevin added: “We have been working closely with Disley Parish Council, High Lane Residents’ Association and the Highways Authority to consider the impact of traffic movements and reduce the environmental impact of the work.”
The scheme is part of United Utilities’ £3.6 billion water quality and environmental improvement programme.
