What Makes Warrington's Water Unique?
Local geology and source profile
Warrington receives its water from United Utilities, a major provider in the North West of England. The utility primarily sources water from upland surface reservoirs, fed by Pennine catchments. These reservoirs are supplemented by boreholes in the southern part of the region. Water treatment occurs at various plants across the service area, ensuring a consistent supply to residents.
The region's water originates from upland moorlands characterized by Carboniferous Millstone Grit and related geological formations. This underlying geology is naturally acidic and contains low mineral content. Consequently, the water drawn from these sources is inherently soft. While boreholes tap into more mineralized aquifers, they are blended with the softer reservoir water.
Residents in Warrington will notice less scale buildup in kettles and appliances, and soap lathers more easily with this soft water supply. United Utilities advises against softening drinking water due to potentially elevated sodium levels, recommending the natural supply for consumption. Most homes won't need additional softening systems. You can check specific water quality details, including hardness and pH, by using the United Utilities postcode checker on their website.
Geology & Source: Millstone Grit (Carboniferous); acidic, low-mineral geology produces soft water
