What Makes Blackpool's Water Unique?

Local geology and source profile

Source: ReservoirTDS: 75.8 mg/LpH: 7.1

Blackpool receives its water from United Utilities, drawing from the Rivington Reservoirs in Lancashire and Pennine upland catchments. This supply is shared with major cities like Manchester and Liverpool, originating from the western Pennine moorlands. The treatment processes ensure the water meets stringent quality standards before reaching consumers' taps, though specific plant names were not detailed in the provided information.

The water's character is shaped by its journey through the Pennine upland catchments. These moorlands, primarily composed of ancient, non-calcareous rocks, contribute to the exceptionally soft nature of the water. Unlike areas with limestone or chalk geology, the moorland bedrock doesn't readily dissolve minerals, resulting in water with very low levels of dissolved solids, particularly calcium and magnesium.

Homeowners in the Blackpool area will likely notice the benefits of this very soft water. It means less limescale buildup in kettles, coffee makers, and especially water heaters, potentially extending their lifespan. You'll also find that soaps and detergents lather more easily, requiring less product for cleaning. While generally beneficial, some people prefer a slightly harder water taste, but the low mineral content poses no risk to health or plumbing.
