What Makes Ashford's Water Unique?
Local geology and source profile
South East Water is the company responsible for supplying water to Ashford. The vast majority of this supply, about 80%, comes from groundwater. This groundwater is drawn from the Chalk aquifer, a significant underground water source beneath the region. After treatment, the water travels through a network of pipes to reach homes and businesses.
The geology beneath Ashford is dominated by Cretaceous Chalk formations. These formations act as a large aquifer system. When rainwater seeps down through the chalk and nearby limestone layers, it picks up minerals like calcium and magnesium carbonates. This natural process, occurring within the soluble chalk bedrock, is what gives the area its characteristically hard water.
This very hard water can lead to noticeable limescale deposits in appliances like kettles and on shower heads. You might also find that washing machines and dishwashers aren't as efficient. To combat this, regularly descale your appliances; a simple clean with vinegar or baking soda can help. Many homeowners find that installing a water softener is the best way to protect their plumbing and make appliances last longer. For specific details about your local water quality, check South East Water's website or contact them directly.
Geology & Source: Chalk aquifer (Cretaceous); dissolution of calcium and magnesium carbonates in chalk and limestone strata produces very hard water
