Royston Water Hardness & Quality Report (2026)

Anglian Water supplies Royston and the wider East of England region, drawing water from a mix of surface reservoirs and rivers, along with groundwater sources. These supplies are processed at various treatment plants before reaching consumers. The company serves a vast area, encompassing counties like Suffolk, Norfolk, and Cambridgeshire, among others. Royston's specific water originates from the East Anglian chalk aquifer, a significant underground water reserve.

The geology beneath Royston is dominated by Cretaceous Chalk formations. This chalk is essentially a highly soluble limestone, which means that as groundwater filters through it, it picks up considerable amounts of calcium and magnesium. This natural process is the reason why the water in this part of England is consistently classified as hard to very hard, with readings frequently falling between 260 and 394 ppm across different postcode districts.

This naturally hard water means you'll likely see scale forming in appliances like kettles and water heaters, impacting their efficiency and lifespan. Soap and detergent won't lather as readily, requiring more product for the same cleaning power. To combat scale, regular cleaning with vinegar or adding washing soda can help, but a whole-house water softener is often recommended for significant reduction.
