What Makes Kingswood's Water Unique?
Local geology and source profile
Bristol Water supplies Kingswood, drawing from Chew Valley Lake and Blagdon Lake in the Mendip Hills. This reservoir supply, originating from the Carboniferous Limestone and the north Somerset plateau, is treated by Bristol Water before reaching residents. The water is characterized as moderately hard, with a hardness level of 12.8°Clark. This regional supply network ensures a consistent flow of treated water to the South Gloucestershire area.
The geology underpinning this water supply is the Carboniferous Limestone found in the Mendip Hills. This type of rock, prevalent in the region, contributes significantly to the water's mineral content, resulting in moderately hard water. The limestone formations act as a natural filter and reservoir, influencing the water's chemical composition as it percolates through the underground strata before being collected for treatment and distribution.
Homeowners in Kingswood may notice the effects of moderately hard water on their appliances. Scale buildup is common in kettles, boilers, and showerheads, necessitating regular descaling to maintain efficiency and prevent damage. While a water softener can mitigate these issues, many residents manage by simply performing routine cleaning. The water's quality, like much of the UK's supply, adheres to strict standards set by the Drinking Water Inspectorate, ensuring it is safe for consumption.
