Water Hardness Breakdown for Sector CM1 4
Serving the community across sector CM1 4, mains tap water is supplied by Essex and Suffolk Water. Across the 313 postcodes within this distribution boundary, the baseline water hardness currently averages 320 PPM, falling into the very hard threshold.
With an intense mineral load of 320 PPM (22.4° Clark), households in CM1 4 face rapid limescale deposition. Dissolved calcium and magnesium leave thick chalky residue on shower screens, aerators, and heating elements while reducing central heating boiler efficiency by up to 18% – 25%+.
Water quality in CM1 4 is monitored continuously under the Water Supply (Water Quality) Regulations. Environmental testing ensures that the 320 PPM mineral density supplied by Essex and Suffolk Water remains compliant with all Drinking Water Inspectorate (DWI) parameters.
In everyday household use, calcium and magnesium ions in 320 PPM water bind with soaps, producing chalky bathroom residue and scum on your morning cuppa. In sector CM1 4, washing laundry or dishware requires +50% extra detergent alongside dedicated limescale inhibitors. For personal grooming, individuals with dry skin or eczema sensitivity may experience skin tightness after showers in this very hard water environment.
Calibrating appliance water softening systems in CM1 4 prevents etched glassware and heating element burnouts. Based on Essex and Suffolk Water's official 320 PPM rating, Bosch dishwashers should be set to H07 (Max Salt).
