What Makes Bexhill-on-Sea's Water Unique?
Local geology and source profile
Bexhill-on-Sea, the East Sussex coastal resort in the Rother District between Hastings and Eastbourne, is supplied by South East Water from the South Downs Chalk Aquifer and licensed chalk boreholes in the chalk country of east East Sussex. South East Water draws from the Cretaceous Upper Chalk of the East Sussex South Downs and from chalk boreholes in the area between the High Weald and the coast — the chalk that forms the downland north of Bexhill and the Pevensey Levels country. The South Downs chalk of east Sussex is part of the continuous Cretaceous Chalk formation of south-east England and produces very high dissolved calcium groundwater. South East Water treats and distributes to Bexhill and the East Sussex coastal belt.
Bexhill's very hard water — 291 mg/L (20.4°Clark) — reflects the South Downs Chalk Aquifer of east East Sussex, where the chalk contributes very high dissolved calcium to the South East Water supply. The TDS of 754.4 mg/L confirms very high total mineral content. The Drinking Water Inspectorate (DWI) classifies this supply as very hard.
Limescale is a very serious daily challenge in Bexhill. At 291 mg/L, thick white limescale forms in kettles within one to two weeks requiring fortnightly descaling. Combi-boiler heat exchangers face very serious limescale risk — annual boiler servicing with limescale inspection and a polyphosphate scale inhibitor are essential. Showerheads, taps, and shower screens develop very heavy deposits. Washing-up liquid lathers very poorly. Bexhill homeowners should strongly consider a whole-house water softener for comprehensive protection against East Sussex chalk limescale damage.
Geology & Source: Supplied by South East Water from the South Downs Chalk Aquifer and Hastings Beds formation of East Sussex — Bexhill's coastal East Sussex position between Hastings and Eastbourne draws on South East Water's chalk borehole and Pevensey/Rother catchment supply from the Cretaceous Chalk of the East Sussex South Downs, producing very hard water at 291 mg/L (20.4°Clark).
