vs. UK Benchmark+10% Hardervs 200 PPM national average
Serving 388 homes and businesses across outcode TS27, mains tap water supplied by Anglian Water registers an average mineral density of 220 PPM (22.0°fH / 12.3°dH). Rated as hard water, local water hardness determines how well laundry detergents lather, the rate of scale accumulation in combi boilers, and whether sensitive skin or eczema flares up after showers.
Water hardness isn't identical across every street in TS27—there is a 180 PPM variance between neighborhoods. Residents in sector TS27 4 enjoy the softest water at 130 PPM, whereas taps in sector TS27 3 register the highest mineral load at 310 PPM. This localized disparity occurs because Anglian Water blends supplies from different boreholes, rivers, and storage reservoirs depending on elevation and seasonal demand.
The reason tap water in TS27 carries significant dissolved minerals lies in local geology. Anglian Water abstracts substantial water supplies from subterranean chalk and limestone aquifers. As rainwater percolates through deep calcium-rich rock strata over decades, it dissolves natural calcium carbonate. While entirely safe and wholesome under Drinking Water Inspectorate (DWI) standards, these minerals precipitate out when heated above 60°C, leaving stubborn limescale deposits on heating coils.
Hard water in TS27 (220 PPM) often causes a cloudy scum on hot drinks and makes soap harder to lather, aggravating dry skin and eczema sensitivity after hot baths. For appliances, ensure regular water softener salt top-ups and calibrate your dishwasher to H04 – H05 to avoid cloudy glassware, white streaks, and heating element burnout across all 388 postcodes.
