What Makes Uppermill's Water Unique?
Local geology and source profile
United Utilities supplies Uppermill with water originating from Dovestones Reservoir, located in the Pennine Millstone Grit uplands of the Saddleworth Tame Valley. This supply is then treated at the Bredbury Water Treatment Works before being distributed to residents. The raw data indicates this process results in hard water, measuring 11.4°Clark.
This water originates from the Pennine region, specifically drawn from Dovestones Reservoir. The underlying geology consists of Millstone Grit, a type of sandstone known for its siliceous composition. Water flowing through this type of rock and terrain tends to pick up minerals, contributing to its classification as hard. The geological makeup of the Saddleworth Tame Valley distribution zone plays a direct role in the water's mineral content.
Consumers in Uppermill may notice the effects of this hard water on their appliances and plumbing. Over time, mineral buildup, or scale, can form inside pipes and water heaters, reducing their efficiency and lifespan. Soap and detergents might also require higher concentrations to lather effectively. For those sensitive to hard water's impacts, installing a water softener can mitigate issues related to scale formation and improve cleaning performance.
Geology & Source: Millstone Grit; upland siliceous sandstone produces hard water
