Eastwood Water Hardness & Quality Report (2026)

Severn Trent Water supplies Eastwood, the birthplace of D.H. Lawrence in west Nottinghamshire. The town's water is drawn from a combination of groundwater from the Permo-Triassic Sherwood Sandstone aquifer — the major regional aquifer of the East Midlands — and reservoir supply from the Derwent Valley complex, treated at regional Nottinghamshire works before distribution across this part of the county. At 160 mg/L (11.2°Clark), Eastwood's water is moderately hard, reflecting the moderate mineralisation of the Sherwood Sandstone aquifer blended with softer upland reservoir water.

The Sherwood Sandstone (Triassic) forms the Nottinghamshire uplands on which Eastwood sits, a gently undulating landscape of red sandstone underlain by the porous aquifer that has supplied the East Midlands with groundwater for centuries. This formation yields water with moderate calcium hardness from interstitial calcite cements and occasional carbonate beds within the Triassic sequence. The Derwent Valley reservoir contribution — sourced from Millstone Grit moorland catchments in the Peak District — dilutes this groundwater hardness to moderate levels in the blended distribution supply.

At 160 mg/L, limescale is a noticeable domestic concern in Eastwood. Kettles benefit from descaling every four to six weeks to maintain element efficiency and avoid calcium deposits in drinks. The combi-boiler should be fitted with a scale inhibitor and serviced annually. Washing-up liquid performs adequately at normal quantities with only slight reduction in lather. Taps and shower heads develop moderate limescale deposits over several weeks; a monthly wipe with white vinegar or a mild descaling product is generally sufficient to keep fittings clean and extend their working life.
