What Makes Stone's Water Unique?
Local geology and source profile
South Staffordshire Water provides service to Stone, Staffordshire, in the West Midlands, reaching more than 1.3 million customers across several counties. The water supply originates from a combination of groundwater boreholes tapping into Triassic sandstone aquifers near Lichfield and Rugeley, alongside surface water drawn from rivers like the River Trent and Blithfield Reservoir. Essential treatment processes occur at facilities such as Hampton Loade and Hampton, where raw water is treated through coagulation, filtration, chlorination, and fluoridation to meet stringent drinking water standards before reaching residents.
The geological landscape around Stone is characterized by Permo-Triassic sandstones and mudstones, formations that are known to be productive aquifers. As rainwater percolates through these ancient rock layers, it dissolves minerals, primarily calcium and magnesium, which are abundant in the local bedrock. This geological process is the main reason for the water's characteristically hard profile, a common trait in the Midlands region, with glacial till also contributing to the overall mineral content.
Homeowners in areas like Stone, where water is moderately hard to hard, will likely notice scale buildup in appliances such as kettles, boilers, and showerheads. This accumulation reduces efficiency and necessitates regular descaling. You might also find that dishwashers and washing machines don't perform as well due to soap scum, and some people report drier skin after showering. Simple solutions include using vinegar to tackle limescale or fitting scale reducers. For persistent issues and to prolong the life of appliances, installing a water softener is a worthwhile consideration.
