What Makes Kimberley's Water Unique?

Local geology and source profile

Severn Trent Water supplies Kimberley, the Nottinghamshire town west of Nottingham in the Borough of Broxtowe — a former mining and hosiery community on the western Nottinghamshire coalfield fringe, known for its independent Kimberley Ales brewery tradition and its position at the edge of the Erewash Valley coalfield north of the city — from Derwent Valley Reservoirs in the Peak District blended with Permo-Triassic Sherwood Sandstone groundwater in the west Nottingham Broxtowe distribution zone, treated at Bamford Water Treatment Works in the Derbyshire Peak District. At 183 mg/L (12.8°Clark), Kimberley's water is hard — reflecting a significant Triassic Sandstone and Carboniferous Coal Measures groundwater contribution in the west Nottingham supply blend.

Kimberley lies on the Permo-Triassic Sherwood Sandstone (Bunter Sandstone) and the fringe of the Carboniferous Coal Measures in the Broxtowe district. Severn Trent blends soft Derwent Valley Peak District reservoir supply with a substantial fraction of Triassic Sandstone and Coal Measures groundwater from the west Nottinghamshire plain, producing 183 mg/L with TDS 479.1 mg/L — hard water with a somewhat elevated TDS/hardness ratio (2.62) consistent with sulphate contributions from the Triassic Keuper Marl and Coal Measures beds in the west Nottingham distribution zone.

At 183 mg/L, limescale is a consistent household challenge in Kimberley. Kettles should be descaled monthly. The combi-boiler benefits from a fitted scale inhibitor and annual professional servicing. Washing-up liquid requires more product per wash. Taps and shower heads develop visible white limescale deposits within one to two weeks; a fortnightly wipe with white vinegar or a proprietary descaling product keeps fittings clean. The hard Triassic Sandstone-blend supply at Kimberley is characteristic of the west Nottinghamshire distribution zone — the Permo-Triassic aquifer beneath the Broxtowe coalfield fringe delivering consistently mineralised water to the community.

Geology & Source: Supplied by Severn Trent Water from Derwent Valley Reservoirs blended with Permo-Triassic Sherwood Sandstone groundwater in the west Nottingham Broxtowe distribution zone — treated at Bamford Water Treatment Works — produces hard water at 183 mg/L (12.8°Clark).
