What Makes Stonehaven's Water Unique?
Local geology and source profile
The primary provider of drinking water for Stonehaven is Scottish Water, a utility serving most of Scotland's population. While the specific sources for Stonehaven weren't detailed in the provided information, Scottish Water generally supplies from reservoirs, rivers, and aquifers, treating the water at various facilities. For Stonehaven, the water originates from Fetteresso Reservoir and is treated at Fetteresso Water Treatment Works. This supply is known for being exceptionally soft, registering at only 1.4°Clark.
The drinking water supply for Stonehaven is sourced from the Fetteresso Reservoir, located in the Aberdeenshire uplands. The geology of this region, characterized by granite and metamorphic rocks typical of the Scottish Highlands, results in water with a very low mineral content. This geological makeup is the reason behind the exceptionally soft nature of the water supplied to the town.
Because the water is very soft, you might notice less limescale buildup in appliances like kettles and boilers compared to areas with harder water. This can contribute to longer appliance lifespans. Soap and detergents may also lather more easily. While specific recommendations aren't needed due to the softness, Scottish Water regularly monitors its supply for safety. Residents can report any issues through the utility's website or hotline.
