What Makes Newcastle under Lyme's Water Unique?

Local geology and source profile

Severn Trent Water supplies Newcastle-under-Lyme in Staffordshire, West Midlands, drawing from a mix of surface water and groundwater sources. The water undergoes treatment at the Staffordshire Treatment Works before being sent out to homes and businesses. This utility serves a vast area, covering over 203 postcode districts across the West Midlands. The hardness of the water can fluctuate depending on the specific location within the supply area and the particular source being utilized at any given time.

The region’s geology plays a significant role in the water's composition. The ground beneath Newcastle-under-Lyme is characterized by Carboniferous and Permian sandstones and mudstones, along with other mineral-rich rock layers. As water travels through these underground formations, it naturally picks up minerals like calcium and magnesium. This geological makeup is the primary reason why the water is classified as moderately hard, a common characteristic for supplies in this part of the country.

Homeowners in Newcastle-under-Lyme might notice some limescale buildup in appliances like kettles, showerheads, and washing machines due to the moderate hardness. Simple maintenance, such as regularly descaling kettles and cleaning showerheads, can help manage this. While a whole-house water softener isn't typically necessary for most households, some individuals with sensitive appliances or particular preferences might opt for one. The water's hardness is actually below the UK's national average and is generally considered suitable for everyday use without requiring special treatment.

Geology & Source: Carboniferous and Permian sandstones and mudstones; limestone and mineral-rich strata cause moderate hardness
