United Utilities gives old service reservoir new lease of life

摘要

United Utilities engineers are working underground to create a new underground service reservoir within an existing service reservoir.The plan is expected to help reduce construction costs by around 75 per cent compared with building a brand-new reservoir. The water company is currently working on a site in St Helens that has three existing underground service reservoirs. Two are no longer operational and the company is utilising the space to construct a completely new service reservoir, which will serve over 60,000 homes in the area.
