Pelsall Water Hardness & Quality Report (2026)

South Staffs Water supplies Pelsall, the south Staffordshire village on the Cannock Chase fringe north of Walsall — a former mining and quarrying community at the south-western edge of Cannock Chase, surrounded by the historic collieries and limestone quarries of the South Staffordshire Coalfield, with pleasant countryside access to the Chasewater Country Park reservoir and nature reserve — from the Elan Valley Aqueduct (Birmingham Corporation Waterworks, Powys upland reservoir supply) blended with Permo-Triassic Sherwood Sandstone (Triassic) groundwater from the Staffordshire plain in the north Walsall distribution zone, treated at Kinver Water Treatment Works near Stourbridge. At 179 mg/L (12.6°Clark), Pelsall's water is hard — reflecting a significant Triassic Sandstone groundwater fraction in the South Staffs Water north Walsall supply blend.

Pelsall lies on the fringes of the South Staffordshire Coalfield where South Staffs Water blends soft Elan Valley Welsh upland reservoir supply with a substantial proportion of Permo-Triassic Sherwood Sandstone groundwater from the Staffordshire–Worcestershire plain. The Triassic Sandstone groundwater contribution elevates hardness to 179 mg/L with TDS 476.1 mg/L — hard water with a slightly elevated TDS/hardness ratio (2.66) indicating minor sulphate from the Triassic Keuper Marl beds in the south Staffordshire distribution zone.

At 179 mg/L, limescale is a consistent household challenge in Pelsall. 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 moderately hard Triassic blend supply at Pelsall is characteristic of the South Staffs Water north Walsall distribution tier — the Permo-Triassic Sandstone aquifer beneath the Chase fringe delivering mineralised groundwater to the north Black Country communities.
