What Makes Dingle's Water Unique?
Local geology and source profile
United Utilities draws its water from a mix of sources to supply the Dingle area. In the south Liverpool distribution zone, water from the Lake District aqueducts is blended with groundwater drawn from the Triassic Sandstone. All of this water is then treated at the Prescot Water Treatment Works before it reaches consumers' taps. This multi-source approach helps ensure a consistent supply for the region's residents.
The water's journey begins in the ancient geology of the Lake District, where runoff collects in reservoirs before flowing through aqueducts. In the south, groundwater percolates through the Triassic Sandstone, a porous rock layer that can impart minerals. The underlying glacial till, a mix of sediments left by ancient ice sheets, also influences the water's composition. These geological formations and deposits contribute to the water's mineral content, resulting in moderately hard water.
With a hardness level of 10.4°Clark, the water is considered moderately hard. This means you might notice some scale buildup in kettles and on heating elements over time. Soap and detergent will lather well, but you might use slightly more than you would with very soft water. If you're concerned about scale affecting appliances like your water heater or dishwasher, regular descaling can help maintain their efficiency. For those sensitive to hardness or seeking to prolong appliance life, a domestic water softener is an option.
Geology & Source: Lake District aqueducts and Triassic Sandstone aquifer; calcareous sandstone and glacial till contribute to moderate hardness
