What Makes Telford's Water Unique?
Local geology and source profile
Severn Trent Water supplies the Telford, West Midlands area, drawing water from a mix of rivers, reservoirs, and groundwater aquifers. The utility manages several treatment facilities to ensure a safe and reliable supply for residents and surrounding communities. Severn Trent Water offers detailed water quality reports accessible via its online portal, allowing customers to check specific information for their postcode. The treatment process includes coagulation, filtration, and chlorination to meet stringent regulatory standards set by the UK Drinking Water Inspectorate.
The Telford area's geology is characterized by Triassic sandstones, mudstones, and marl formations, with some Carboniferous coal measures nearby. Groundwater sources in this region traverse mineral-rich strata, including limestone and clay layers. As water percolates through these deposits, it dissolves calcium and magnesium compounds, giving the supply its naturally hard quality, a common trait for water in the West Midlands.
Homeowners in Telford will likely notice the effects of hard water, such as limescale buildup on fixtures like taps and showerheads, and inside appliances such as kettles and boilers. This mineral accumulation can reduce the efficiency and lifespan of washing machines, dishwashers, and water heaters. To combat these issues, many households opt for domestic water softeners, which also improve the lathering of soaps and detergents. Routine cleaning with vinegar or descaling solutions can help manage existing scale on surfaces. Severn Trent Water provides comprehensive quality data on its website.
Geology & Source: Triassic sandstones and mudstones; limestone and marl deposits contribute to hard water
