What Makes Wigston Magna's Water Unique?
Local geology and source profile
Wigston Magna, in south Leicestershire immediately south of Leicester city, is supplied by Severn Trent Water from the River Soar catchment and the Triassic Sherwood Sandstone aquifer of south Leicestershire. The River Soar flows south through the Leicestershire plain, draining the Charnwood Forest Pre-Cambrian upland (calcium-poor ancient rocks) and the Triassic plains of north Leicestershire, carrying moderate dissolved calcium from the Triassic sediments. Severn Trent draws from the Soar at Mountsorrel and from Triassic sandstone boreholes in the south Leicestershire supply zone, treating at Leicester-area works and distributing through the south Leicester network. The blend of soft Charnwood catchment input and moderate Triassic sandstone groundwater produces a moderately soft supply for Wigston Magna.
Wigston Magna's hardness of 129.5 mg/L (9.1°Clark) reflects the blend of soft Charnwood Forest upland catchment and moderate Triassic Sherwood Sandstone groundwater in Severn Trent's south Leicestershire supply zone. The Drinking Water Inspectorate (DWI) classifies this supply as moderately soft.
Limescale is a moderate concern in Wigston Magna. At 129.5 mg/L, limescale forms gradually — kettles need descaling every one to two months. Combi-boiler heat exchangers accumulate modest deposits; annual servicing is sensible. Showerheads and taps develop light deposits. Washing-up liquid lathers reasonably well. A monthly Calgon tablet in the washing machine and a regular kettle descale is adequate limescale management for most Wigston Magna households.
Geology & Source: Supplied by Severn Trent Water from the River Soar and Triassic Sherwood Sandstone aquifer of south Leicestershire — Wigston Magna's south Leicester position draws on Severn Trent's blended Soar valley and Triassic sandstone supply, producing moderately soft water at 129.5 mg/L (9.1°Clark).
