What Makes New Milton's Water Unique?
Local geology and source profile
South East Water provides the water supply for New Milton and surrounding communities in Hampshire, UK. The utility draws primarily from groundwater, with boreholes like Walkford and Barton tapping into the extensive Chalk aquifer that lies beneath the Hampshire Basin. This important source is replenished by rainfall percolating through the Hampshire Downs and Solent Basin. Water undergoes treatment at facilities such as the New Milton Water Treatment Works before reaching residents.
The groundwater in this region flows through the Upper Cretaceous Chalk, a porous and fractured limestone formation known for its high calcium carbonate content. Rainwater dissolves these minerals as it travels underground, leading to naturally hard water. This geological characteristic is typical of southeastern England's limestone areas, contrasting with the softer water found in regions with different bedrock, such as granite or peat.
Homeowners in New Milton will likely notice the effects of hard water on their appliances and plumbing. Limescale buildup is a common issue, particularly affecting kettles, boilers, and showerheads, which can reduce their efficiency and shorten their lifespan. Regular descaling using household solutions like vinegar can help manage these deposits. For a more comprehensive solution, installing a water softener is often recommended to improve soap lathering, protect appliances, and reduce the visible scum on taps and fixtures.
Geology & Source: Chalk aquifer; porous limestone rich in calcium carbonate; calcareous nature of Chalk Group produces hard water
