What Makes Stanley's Water Unique?
Local geology and source profile
Northumbrian Water supplies Stanley residents with water drawn from a mix of sources. The primary inputs are Derwent Reservoir and water transferred from Kielder Water. This surface water undergoes treatment before reaching homes. However, the distribution network picks up some influence from the Magnesian Limestone geology, which contributes to the water's characteristics as it travels to your tap.
The water's journey begins in the north, drawing from large reservoirs. As it flows through the pipes towards Stanley, it interacts with the underlying Magnesian Limestone formations. This geological layer is known for its mineral content, particularly calcium carbonate, which dissolves into the water. This interaction is the reason the water is classified as moderately hard, registering around 12.3 degrees on the Clark scale.
Homeowners in Stanley may notice the effects of this moderately hard water on their appliances. You might find scale buildup more frequently in kettles and around taps, potentially shortening the lifespan of water heaters and dishwashers. Using less soap and detergent can help, and regular descaling of appliances is recommended. A water softener can significantly reduce these issues, improving the water's performance in your home.
Geology & Source: Magnesian Limestone influence; limestone bedrock produces moderate hardness
