Wells Water Hardness & Quality Report (2026)

South West Water supplies the region of Devon, Cornwall, and parts of Somerset, including the town of Wells. The utility draws its water from numerous moorland rivers and reservoirs across the South West peninsula. Key sources include large reservoirs like Colliford Lake and Siblyback Lake, alongside river intakes from these upland catchments. This raw water undergoes treatment at various facilities before reaching the approximately 1.8 million residents served by South West Water.

The water supply originates from an area defined by Devonian granite bedrock and acidic moorland geology, particularly noticeable in the high grounds of Dartmoor and Bodmin Moor. This landscape's composition, characterized by crystalline bedrock and acidic soils, means the water naturally collects with very low levels of dissolved minerals like calcium and magnesium. In stark contrast to areas with limestone geology, the South West's natural environment produces water that remains soft throughout its journey to the treatment plants.

Homeowners in the Wells area and throughout the South West Water service territory will find this naturally soft water is gentle on appliances and plumbing. You'll notice very little scale buildup in kettles, on showerheads, or inside pipes. Soap and detergents lather easily, meaning you likely won't need extra conditioning products. Maintaining water-using devices like water heaters and dishwashers is generally simpler, and the soft water is often preferred for personal care. Consequently, installing a domestic water softener is unnecessary for this supply.
