Mansfield Woodhouse Water Hardness & Quality Report (2026)

Severn Trent Water supplies Mansfield Woodhouse, a former colliery and hosiery village directly north of Mansfield in the Nottinghamshire coalfield. The town's water is drawn from a combination of groundwater from the Permo-Triassic Sherwood Sandstone aquifer — the productive regional aquifer outcropping west of the town — and reservoir supply from the Derwent Valley complex, treated at Linacre Water Treatment Works and regional Nottinghamshire facilities. At 187.5 mg/L (13.2°Clark), Mansfield Woodhouse's water is moderately hard, reflecting the mineral character of the Sherwood Sandstone aquifer dominant in this part of Nottinghamshire.

The Sherwood Sandstone (Triassic) outcrops extensively west of Mansfield Woodhouse, dipping eastward beneath the coalfield and providing the principal groundwater resource for the Mansfield supply zone. This formation yields water with moderate calcium hardness from interstitial calcite cements and occasional carbonate beds in the Triassic sequence. The softer Derwent Valley reservoir water from Millstone Grit Peak District catchments dilutes the Sherwood Sandstone groundwater to moderately hard levels in the blended distribution supply reaching Mansfield Woodhouse.

At 187.5 mg/L, limescale is a noticeable domestic concern in Mansfield Woodhouse. 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 a few weeks; a monthly wipe with white vinegar or a mild descaling product keeps fittings clean. Scale inhibitors for the boiler and main appliances are a worthwhile investment at this hardness level.
