What Makes Ashford's Water Unique?
Local geology and source profile
South East Water supplies Ashford residents with water sourced from the North Downs and Greensand Ridge Chalk Aquifer. This aquifer, located in the Kentish Weald, is accessed via deep boreholes. The water then undergoes treatment at facilities operated by the utility before distribution to homes and businesses across the area. This mixed supply strategy ensures a consistent flow of water to meet demand.
Ashford's water originates from the Chalk Aquifer, a significant geological feature underlying the Kentish Weald. The specific location between the North Downs and the Greensand Ridge influences the water's characteristics. Abstraction from deep boreholes within this chalk formation results in water that is exceptionally hard, containing a very high concentration of total dissolved solids, a direct result of the mineral content dissolved from the chalk bedrock over long periods.
With water hardness measured at 25.5°Clark, residents will likely notice the effects on appliances and plumbing. Scale buildup can significantly shorten the lifespan of water heaters, dishwashers, and kettles. You may find that soaps and detergents don't lather as easily, requiring more product for cleaning. Regular descaling of appliances and pipes is recommended. Consider installing a water softener to protect your household fixtures and improve cleaning efficiency.
Geology & Source: Chalk aquifer; deep borehole abstraction produces extremely hard water with very high total dissolved solids
