Swansea Water Hardness Report
Official mineral water quality analysis, local catchment breakdown, appliance salt calibration, and postcode outcode directory for Swansea.
Swansea
Swansea tap water is naturally very soft, averaging just 45 PPM. Sourced by Dŵr Cymru Welsh Water from upland reservoirs across the Black Mountain and Brecon Beacons (such as Cray and Lliw reservoirs), the supply flows through siliceous rock and moorland peat with almost zero calcium content. Swansea households enjoy scale-free kettles, glistening chrome taps, and silky showers where a tiny dab of shampoo creates rich, luxurious foam.
Neighbourhood Hydro-Variance
Water hardness across Swansea varies by up to 30 PPM between different treatment zones and boreholes.
Soft Water Zone Detected (SA averages 45 PPM): Pure Water Solutions
Because your water is naturally soft, you do not need an expensive salt softener (£1,200+). Explore DIY drinking water filters or compare local specialists for boiler care.
