Evington Water Hardness & Quality Report (2026)

Severn Trent Water supplies Evington, a residential suburb in the south-east of Leicester. Supply is drawn from Rutland Water — England's largest artificial reservoir by surface area — fed by the Rivers Welland and Gwash draining the Jurassic limestone of Rutland, supplemented by Lincolnshire Limestone and Triassic Sherwood Sandstone groundwater, treated at regional Leicester area works. At 152.5 mg/L (10.7°Clark), Evington's water is moderately soft — less hard than some other Leicester zones — reflecting the specific distribution blend reaching south-east Leicester from the Severn Trent network.

Rutland Water receives water from the Jurassic limestone catchments of Rutland and Northamptonshire, carrying characteristic calcium hardness from the Great Oolite and Lincolnshire Limestone formations. The Triassic Sherwood Sandstone aquifer in the East Midlands contributes moderate-hardness groundwater. The blend served to Evington is diluted compared to zones receiving higher Rutland Water proportions, resulting in moderately soft water at 152.5 mg/L with a TDS of 358.2 mg/L — a somewhat lower dissolved mineral load than the Leicester city average.

At 152.5 mg/L, limescale is a manageable domestic concern in Evington. Descaling the kettle every six to eight weeks is typically adequate. The combi-boiler benefits from a standard scale inhibitor as a precaution. Washing-up liquid lathers satisfactorily at normal quantities. Taps and shower heads develop light to moderate limescale deposits over a few weeks; a monthly wipe with white vinegar or a mild descaling product keeps fittings in good condition. The moderately soft supply in this part of Leicester is comfortable for domestic use without requiring intensive limescale management.
