Atherstone Water Hardness & Quality Report (2026)

South Staffordshire Water supplies Atherstone in North Warwickshire, West Midlands, serving over 1.3 million customers. The water comes from a mix of groundwater drawn from boreholes in Triassic sandstone aquifers, and surface water from reservoirs and the River Tame and Blithfield Reservoir. Treated at facilities like the Atherstone Water Treatment Works, the supply is also supplemented by Severn Trent Water in some areas. This diverse sourcing ensures a consistent provision for residents, reflecting the region's naturally mineral-rich geology.

The watershed feeding Atherstone is part of the River Anker sub-basin within the Trent catchment. Here, water flows over Triassic Mercia Mudstone Group and Sherwood Sandstone Group aquifers, with nearby Carboniferous Limestone outcrops also influencing its mineral content. These sedimentary rock layers, formed between 200 and 300 million years ago, readily dissolve calcium and magnesium as rainwater seeps through them. This natural process results in a water supply that is typically moderately hard to hard, a stark contrast to the softer water found in more mountainous regions.

Homeowners in Atherstone will likely notice the effects of this moderately hard to hard water, particularly with limescale buildup inside kettles, boilers, and on showerheads. This accumulation can reduce the efficiency and shorten the lifespan of heating systems and appliances such as washing machines and dishwashers, potentially clogging pipes over time. Regular descaling with household solutions like vinegar can help, as can using filter jugs or magnetic conditioners. For significant protection against damage, improved soap lathering, and softer skin and hair, a water softener is often recommended for households in this area.
