Wellington Water Hardness & Quality Report (2026)

Wellington, the historic market town in Telford and Wrekin east of Telford new town in east Shropshire — with a claim to have the first iron bridge in the world nearby at Ironbridge — is supplied by Severn Trent Water from the River Severn and Lake Vyrnwy supply infrastructure. Severn Trent draws on the Severn at Llandinam, Llanidloes and other upper Severn abstractions in mid-Wales, and on Lake Vyrnwy — the large Victorian upland reservoir in the Berwyn Mountains of north Powys — to supply the Shropshire and Telford zone. Both the upper River Severn and Lake Vyrnwy drain Silurian greywacke and mudstone and Ordovician volcanic rocks of mid-Wales — calcium-depleted formations producing moderately soft supply water. Water is treated at Shelton Water Treatment Works in Shrewsbury before distribution east through Shropshire to Wellington. At 117 mg/L with TDS 282.9 mg/L, Wellington's supply is moderately soft — harder than the pure Welsh upland supply zones (60–80 mg/L) but softer than the Midlands limestone zones (200+ mg/L), reflecting the Severn valley blend of Welsh upland and Shropshire valley supply.

The River Severn drains the Cambrian, Ordovician and Silurian sedimentary rocks of central Wales above Shrewsbury, acquiring modest calcium bicarbonate from the Silurian limestone and calcareous siltstone outcrops of the Welsh border. Lake Vyrnwy drains the purely Silurian greywacke Welsh upland, contributing softer, less mineralised water. The blend at Shelton WTW produces the 110–120 mg/L moderately soft supply characteristic of the Shropshire plain, harder than the Welsh upland reservoirs alone but softer than the east Midlands Triassic and limestone zones downstream.

At 117 mg/L Wellington's water is moderately soft and limescale is a manageable domestic concern. Kettles benefit from descaling every six to eight weeks. Shower screens stay relatively clean with weekly wipe-down. Washing-up liquid lathers well. Combi-boilers face moderate scaling risk. Wellington's Shropshire market-town character — a traditional economy surrounded by farm countryside and the legacy of the first Industrial Revolution at Ironbridge — is served by the Severn's moderately soft Welsh-influenced water that has flowed through this corner of the Welsh Marches for centuries.
