Meadowhall (shopping centre) and retailers for flushing toilets is derived from rainwater harvesting or bore hole water. Meadowhall (shopping centre) Meadowhall is an indoor shopping centre in Sheffield, South Yorkshire, England. It lies north-east of Sheffield city centre and from Rotherham town centre. It is the largest shopping centre in Yorkshire and currently the eighth largest in the United Kingdom, however plans for an extension are currently underway for the 2020s, which would make Meadowhall the fourth largest shopping centre in the United Kingdom. The Meadowhall Retail Park is a separate development, owned by British Land, lying almost to the south of Meadowhall
Meadowhall (shopping centre) began to harvest rainwater in 2006. Four water storage tanks collect rainwater and condensation from air conditioning. This is then used throughout the Shopping Centre for cleaning, flushing toilets and watering the external landscaped areas. The tanks are nearly 7 metres high and hold some of water each. In 2008 Meadowhall installed a bore hole. This is a narrow shaft drilled into the ground that collects water from beneath the earth. Water from the bore hole is collected into a master tank. The storage tanks are connected onto a "network", which will ensure 90-95% of all water used by customers
