What Makes Ashby-de-la-Zouch's Water Unique?

Local geology and source profile

Source: MixedTDS: 361.2 mg/LpH: 8

South Staffordshire Water provides the Ashby-de-la-Zouch area with water sourced from local groundwater aquifers. Treatment facilities, such as the Measham or Packington plants, serve the district, which is part of a larger network delivering to over 1.3 million customers across Staffordshire, Derbyshire, and Leicestershire. The supply is predominantly from boreholes, drawing from the Trent Valley catchment where Permo-Triassic sandstones and mudstones form the primary aquifer. This region's geology significantly influences the water's mineral content.

The underlying geology consists of Permo-Triassic formations, including the Mercian Mudstone Group and Sherwood Sandstone Group. These strata are rich in calcareous deposits, meaning that as rainwater percolates through the porous and sometimes fissured sandstones and limestone-influenced layers, it dissolves calcium and magnesium. This process naturally hardens the water, a characteristic common in the Midlands basin, contrasting with the softer water found in western upland areas. The ancient rock layers impart a distinct mineral profile to the supply.

This naturally hard water can lead to limescale buildup in appliances like kettles, boilers, and showerheads, potentially reducing their efficiency and lifespan. You might notice increased energy consumption in dishwashers, washing machines, and heating systems, sometimes by as much as 20-30%. To manage scale, regular descaling with vinegar or installing limescale filters can help. For significant issues, a whole-house water softener is often recommended to protect your appliances and improve how soap lathers. South Staffs Water reports that water quality meets UK standards, with pH typically between 7.2 and 7.6.
