Plymouth Water Hardness Report
Official mineral water quality analysis, local catchment breakdown, appliance salt calibration, and postcode outcode directory for Plymouth.
Plymouth
Plymouth tap water is amongst the purest and softest in the UK, measuring an average of just 34 PPM. South West Water sources Plymouth's supply from Dartmoor National Park (Burrator Reservoir) and the River Tamar. Flowing across impermeable Dartmoor granite and peat moorlands, the water collects virtually no calcium or magnesium. Plymouth households enjoy scale-free kettles, sparkling shower glass, and luxurious soap lather, with zero need for domestic water softeners.
Neighbourhood Hydro-Variance
Water hardness across Plymouth varies by up to 23 PPM between different treatment zones and boreholes.
