What Makes Stamford's Water Unique?
Local geology and source profile
Anglian Water supplies Stamford's drinking water, drawing from a mixed source. The primary sources include the Lincolnshire Limestone and Jurassic Oolite aquifers, supplemented by water from the River Welland catchment. This raw water undergoes treatment at regional East Midlands facilities before reaching households.
The water's journey to your tap begins deep underground in the Jurassic period's limestone formations, specifically the Lincolnshire Limestone and Jurassic Oolite aquifers. These geological layers are known to impart minerals to the water flowing through them. Consequently, the water is classified as moderately hard, registering at 12.6 degrees Clark.
This moderately hard water may lead to some scale buildup over time, particularly in appliances like kettles and water heaters. You might notice that soap and detergents don't lather quite as readily as with softer water. Regular descaling of appliances can help maintain their efficiency and lifespan. While not a health concern, managing scale is a practical consideration for homeowners in the area.
