What Makes Featherstone's Water Unique?
Local geology and source profile
Yorkshire Water supplies Featherstone, the west Yorkshire town in the City and Borough of Wakefield — a proud former coal mining and rugby league town in the Aire and Calder coalfield east of Wakefield, home of Featherstone Rovers RLFC and a community that epitomised the culture of the Yorkshire mining industry through the 1984–85 Miners' Strike and its aftermath — from Pennine upland reservoirs in the west Yorkshire Wakefield supply zone, treated at Scammonden Water Treatment Works on the moorland above the M62 near Huddersfield. At 99 mg/L (6.9°Clark), Featherstone's water is slightly hard — reflecting modest calcium contributions from the Carboniferous Coal Measures and Millstone Grit upland catchments of the west Yorkshire Pennine reservoirs.
Featherstone lies in the west Yorkshire coalfield lowland east of Wakefield, supplied from Yorkshire Water's Pennine reservoir network on the Carboniferous Millstone Grit and Coal Measures moorland. The soft Pennine reservoir supply is distributed through the Wakefield coalfield network, picking up modest calcium from the Coal Measures distribution zone to produce 99 mg/L with TDS 225.2 mg/L — slightly hard water consistent with the west Yorkshire coalfield supply tier at Pontefract (97 mg/L), Castleford, and Normanton in the same Yorkshire Water Wakefield distribution corridor.
At 99 mg/L, limescale is a moderate and manageable domestic concern in Featherstone. Descaling the kettle every two to three months is typically adequate. The combi-boiler benefits from a standard scale inhibitor as a precaution. Washing-up liquid lathers adequately. Taps and shower heads develop moderate deposits over several months; a quarterly wipe with white vinegar keeps fixtures in good order. Featherstone's slightly hard Pennine supply reflects the Yorkshire coal country — Millstone Grit moorland water travelling through a coalfield distribution zone, picking up just enough Coal Measures mineralisation to leave a modest trace on the kettle.
