Bradwell Water Hardness & Quality Report (2026)

Anglian Water supplies Bradwell, the residential community adjacent to Great Yarmouth in the Great Yarmouth Borough on the Norfolk coast — a suburb of Great Yarmouth on the south side of the Bure–Yare–Waveney river confluence, part of the urban area surrounding Norfolk's principal seaside resort, with a community growing from the expansion of Great Yarmouth's residential hinterland — from the Norfolk Chalk (Cretaceous) confined aquifer boreholes in the Great Yarmouth coastal supply zone, treated at Heigham Water Treatment Works near Norwich. At 301.5 mg/L (21.1°Clark) and a TDS of 850.9 mg/L, Bradwell's water is extremely hard — consistent with the deep confined Upper Chalk (Cretaceous) aquifer of the Norfolk coastal zone that delivers highly concentrated, mineralised groundwater to the Great Yarmouth area.

Bradwell lies in the Great Yarmouth coastal plain where Anglian Water draws from deep confined Norfolk Chalk boreholes. The confined chalk aquifer delivers highly concentrated calcium carbonate, further enriched by sulphate from the Red Crag and Norwich Crag (Pliocene marine sediments) overlying the chalk, and by Gault Clay derived sulphate from beneath the chalk, producing 301.5 mg/L with TDS 850.9 mg/L — extremely hard water with an elevated TDS/hardness ratio (2.82) characteristic of the Anglian Water Norfolk coastal chalk supply zone.

At 301.5 mg/L, limescale is a severe household problem in Bradwell. Kettles should be descaled every week to ten days. The combi-boiler requires a fitted scale inhibitor and annual professional servicing as a minimum. Washing-up liquid requires very generous quantities. Taps and shower heads develop heavy white chalk deposits within days; frequent descaling with white vinegar or a proprietary product is necessary. A whole-house water softener is strongly recommended — at 301.5 mg/L, the Great Yarmouth area confined chalk supply is one of the hardest in England, and protecting household appliances from limescale is a practical investment that pays for itself many times over in any Bradwell home.
