Featherstone Water Hardness & Quality Report (2026)

South Staffordshire Water supplies Featherstone, a village in Staffordshire north of Wolverhampton near Cannock Chase — a community historically linked to the nearby coal mines and now a Wolverhampton suburb — from the Elan Valley aqueduct (shared with Severn Trent Water) and local Permo-Triassic Sandstone (Sherwood Sandstone) groundwater from the Staffordshire and Cannock Chase area, treated at Blithbury Water Treatment Works near Rugeley. At 106.5 mg/L (7.5°Clark), Featherstone's water is soft, reflecting the dominance of the soft Welsh upland aqueduct supply that characterises South Staffordshire Water's north Staffordshire distribution zone.

The Elan Valley aqueduct — built by Birmingham Corporation in 1904 — carries naturally soft water from Dalradian and Silurian hard rock reservoirs in the Cambrian Mountains of Wales across 118 kilometres to the West Midlands. South Staffordshire Water draws on this Welsh aqueduct supply to serve communities in south and north Staffordshire, delivering soft low-mineral water to Featherstone and the Cannock Chase fringe. The 106.5 mg/L with TDS 242.3 mg/L reflects the soft Elan supply blended with a modest Triassic Sandstone groundwater contribution beneath the Cannock Chase area.

At 106.5 mg/L, Featherstone's soft water is comfortable for domestic use with moderate limescale demands. Descaling the kettle every two to three months is typically adequate. The combi-boiler benefits from a standard scale inhibitor as a sensible precaution. Washing-up liquid lathers well at everyday quantities. Taps and shower heads remain relatively clean with only occasional maintenance. The soft Elan Valley supply reaching Featherstone and the Cannock Chase–Wolverhampton fringe communities is a legacy of the great Victorian Welsh water supply infrastructure built to support the growth of the West Midlands industrial region.
