Belgrave Water Hardness & Quality Report (2026)

Severn Trent Water supplies Belgrave, the inner north Leicester suburb in the City of Leicester — a diverse and vibrant community, home to Leicester's famous Golden Mile of South Asian restaurants and jewellers along Belgrave Road, and the Shree Sanatan Mandir temple complex — from Derwent Valley Reservoirs in the Peak District blended with Permo-Triassic Sandstone (Sherwood Sandstone) groundwater in the north Leicester distribution zone, treated at Loughborough Water Treatment Works. At 204 mg/L (14.3°Clark), Belgrave's water is hard — reflecting the Triassic Sandstone and Mercia Mudstone (Keuper Marl) groundwater contribution in the north Leicester supply blend.

Belgrave sits in the inner north Leicester distribution zone where Severn Trent Water blends soft Derwent Valley Peak District upland reservoir supply with a substantial fraction of Permo-Triassic Sherwood Sandstone and Mercia Mudstone groundwater from the Leicestershire lowland. The Triassic contribution elevates hardness to 204 mg/L with TDS 541.7 mg/L — hard water with a somewhat elevated TDS/hardness ratio (2.66) suggesting minor sulphate from the Keuper Marl gypsum beds that underlie much of the north Leicester plain.

At 204 mg/L, limescale is a persistent household challenge in Belgrave. 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 hard Triassic Sandstone-blend supply at Belgrave is a consistent domestic feature of north Leicester life — as reliably present in the community's kitchens as the spices and saris on Belgrave Road.
