Bridport Water Hardness & Quality Report (2026)

Wessex Water supplies Bridport, the historic rope and net-making town on the west Dorset coast near West Bay — the fishing harbour made famous by the TV series *Broadchurch* — from Jurassic Limestone springs and the River Brit catchment in the west Dorset supply zone, treated at Bridport Water Treatment Works. At 133 mg/L (9.3°Clark), Bridport's water is slightly hard — reflecting the moderate calcareous character of the Jurassic Limestone (Inferior Oolite and Bridport Sands) geology that defines the landscape around the town and contributes modest calcium to the spring and river supply.

Bridport lies in the West Dorset Jurassic Coast hinterland where the Inferior Oolite and Upper Lias Limestone cap the rolling west Dorset plateau above the Brit valley. Wessex Water draws on limestone springs and the River Brit catchment in the Bridport supply zone, yielding 133 mg/L with TDS 301.4 mg/L — slightly hard water with a characteristic Jurassic limestone bicarbonate quality, softer than the chalk-dominant east Dorset zones (209–238 mg/L) but harder than the pure Mendip or Somerset upland baseline.

At 133 mg/L, limescale is a moderate and manageable domestic concern in Bridport. Descaling the kettle every six to eight weeks is typically adequate. The combi-boiler benefits from a standard scale inhibitor as a precaution. Washing-up liquid lathers adequately at everyday quantities. Taps and shower heads develop light deposits over several weeks; a monthly wipe with white vinegar keeps fixtures in good condition. The slightly hard Jurassic limestone supply at Bridport is characteristic of west Dorset's gentle calcareous landscape — modest, pleasant, and fitting for the atmosphere of this unhurried coast-and-country market town.
