Faversham Water Hardness & Quality Report (2026)

South East Water supplies Faversham, drawing water from a mix of groundwater and surface sources. The primary source is the Chalk aquifer, a vast underground reservoir beneath the North Kent Basin. Water is treated at facilities that process this chalk reserve before it reaches the area's customers. The utility serves a significant portion of Kent and Sussex, managing supply for millions across the region.

The Chalk aquifer, a fine-grained limestone from the Cretaceous period, is the bedrock of Faversham's water supply. As rainwater filters through Tertiary clay and into this chalk formation, it picks up substantial amounts of calcium carbonate. This geological process, common throughout south-east England, naturally results in a hard, mineral-rich water characteristic of the North Kent Basin.

Expect to see limescale forming in appliances like kettles and shower heads due to this hard water, which can also make soaps and detergents less effective. Homeowners often find a water softener beneficial for protecting plumbing and extending the life of appliances such as dishwashers. To combat scale buildup, a descaling routine every few months is a good idea for heating elements and pipes. You can check your specific water hardness by visiting the South East Water website.
