Bedlington Water Hardness & Quality Report (2026)

Northumbrian Water supplies Bedlington, a former colliery town in south-east Northumberland. Supply is drawn from Kielder Water — Europe's largest artificial reservoir by volume, impounded on the North Tyne in the Northumberland National Park — and supplemented by local river abstraction from the Northumberland coalfield rivers, treated at Horsley Water Treatment Works before distribution across Northumberland and Tyneside. At 152.5 mg/L (10.7°Clark), Bedlington's water is moderately soft, reflecting the blending of very soft Kielder reservoir water with slightly harder lowland river and groundwater components in the coalfield distribution zone.

Kielder Water is fed by the North Tyne and its tributaries draining ancient Lower Palaeozoic and Carboniferous rocks of the Border hills — andesites, greywackes, and sandstones with minimal calcium carbonate — producing naturally soft, slightly acidic reservoir water. The distribution blend in Bedlington, however, incorporates contributions from local Carboniferous Coal Measures sandstone aquifers and river sources in the Northumberland plain, which add modest calcium hardness. The result is the moderately soft supply characteristic of Northumbrian Water communities in the coastal lowland belt.

At 152.5 mg/L, limescale is a noticeable but manageable concern in Bedlington. Descaling the kettle every six to eight weeks is typically sufficient. The combi-boiler benefits from a fitted scale inhibitor and annual servicing. Washing-up liquid performs well at everyday quantities. Taps and shower heads develop moderate limescale deposits over a few weeks; a monthly wipe with white vinegar keeps fittings in good condition. Bedlington's water is considerably softer than south-east England equivalents, and household appliances generally enjoy a longer working life as a result.
