Water Hardness Breakdown for Sector RG12 2
Covering 148 active delivery postcodes in the RG12 district, households and businesses in sector RG12 2 are supplied with tap water averaging 270 PPM (18.9° Clark). Distributed under the regulatory oversight of South East Water, local tap water supplies in this catchment are rated as hard.
Registering 270 PPM, tap water across RG12 2's 148 postcodes carries significant calcium concentrations. Uninhibited hot water use accelerates limescale deposits on heating elements, potentially causing a 10% – 15% loss in boiler heat transfer efficiency over prolonged operating cycles.
Water distributed by South East Water in this southeastern/eastern catchment is predominantly drawn from underground chalk and limestone aquifers. As rainwater filters through deep subterranean chalk strata, it naturally dissolves high concentrations of calcium bicarbonate, resulting in the consistent 270 PPM profile recorded across sector RG12 2.
In everyday household use, calcium and magnesium ions in 270 PPM water bind with soaps, producing chalky bathroom residue and scum on your morning cuppa. In sector RG12 2, washing laundry or dishware requires +35% extra laundry detergent to overcome calcium neutralization. For personal grooming, individuals with dry skin or eczema sensitivity may experience skin tightness after showers in this hard water environment.
Calibrating appliance water softening systems in RG12 2 prevents etched glassware and heating element burnouts. Based on South East Water's official 270 PPM rating, Bosch dishwashers should be set to H04. Consult the interactive equipment guide below for custom brand settings across all 148 postcodes.
