What Makes Peterhead's Water Unique?

Local geology and source profile

Source: ReservoirTDS: 11.6 mg/LpH: 7

Scottish Water supplies Peterhead from Loch Strathbeg and upland reservoirs located on the Buchan plateau in Aberdeenshire. The water undergoes treatment at regional Grampian facilities before reaching homes and businesses. This source is known for yielding naturally soft water, making it a key characteristic of the local supply. The reliability of these sources ensures a consistent flow to the community.

The water's journey begins in the Scottish Highlands, flowing from the Buchan plateau. This region is characterized by ancient igneous and metamorphic rock formations. These geological features are key to the water's softness, as they contain very few of the minerals that cause hardness. Unlike water that flows over limestone or chalk, the water here picks up minimal dissolved solids, resulting in its exceptionally low mineral content and resulting soft nature.

Residents may notice that soap lathers easily and less detergent is needed for laundry. Because the water is so soft, it's less likely to cause scale buildup in pipes and appliances like kettles and water heaters, potentially extending their lifespan. While generally pleasant tasting, some people accustomed to harder water might find the taste different. If you're looking for ways to enhance your experience with soft water, consider simple cleaning techniques that require less product and are gentler on surfaces.

Geology & Source: Upland reservoirs; igneous and metamorphic rocks of the Buchan plateau produce very soft water
