What Makes Kimberley's Water Unique?

Local geology and source profile

Severn Trent Water supplies Kimberley, drawing from a mix of surface and groundwater sources across the East Midlands. While the utility serves a wide area, specific reservoirs and treatment facilities for Kimberley aren't detailed here, requiring a look at Severn Trent Water's service maps. The water originates from the Nottinghamshire coalfield watershed. This region's geology, characterized by Carboniferous Coal Measures and Millstone Grit formations, is rich in dissolved minerals like calcium and magnesium, which naturally contribute to the hardness of the local water.

The Nottinghamshire coalfield geology, featuring Carboniferous Coal Measures and Millstone Grit, is the primary reason for Kimberley's water hardness. These rock strata are known to be rich in minerals, particularly calcium and magnesium compounds. This geological makeup is characteristic of the East Midlands, where mineral-rich groundwater and surface water sources consistently yield hard water supplies for the region's residents.

Homeowners in Kimberley may notice limescale buildup in appliances such as kettles and water heaters, requiring more detergent for laundry and dishes. To combat these effects and extend the life of your appliances, installing a whole-house water softener is often recommended for areas with this level of hardness. For the most accurate picture of your specific water quality, including details on pH and compliance with drinking water standards, consult Severn Trent Water's online resources using your postcode.
