What Makes Longsight's Water Unique?

Local geology and source profile

Source: MixedTDS: 240.9 mg/LpH: 7.6

United Utilities supplies Longsight residents with water from two main sources. In the west, the supply comes from the Lake District via aqueducts, while the eastern part of the distribution zone receives a blend with groundwater drawn from the Sherwood Sandstone. Both sources are treated at the Godley water treatment works and other regional Manchester facilities before reaching homes.

The Sherwood Sandstone aquifer, a significant geological feature in the region, is known for yielding water that is naturally low in dissolved minerals. Combined with the water from the Lake District sources, this results in a supply that is characterized as moderately soft. This geological background is key to understanding the water's properties as it moves through the distribution system.

Homeowners in Longsight may notice that this moderately soft water lathers soap and detergent easily, requiring less product for cleaning tasks. You'll also find it's generally kinder to appliances like washing machines and dishwashers, potentially extending their lifespan by reducing the build-up of mineral scale. While it doesn't typically require a water softener, occasional light descaling of kettles or coffee makers might be beneficial for optimal performance.
