Water in Wiltshire
- Wiltshire sits largely on chalk downland and has hard water, generally 220 to 310 mg/l CaCO₃.
- The Salisbury Plain chalk aquifer is a major regional water resource.
- The county is predominantly rural with a substantial number of properties on private supplies, making UV and sediment treatment more relevant here than in urban counties.
- Scale protection at boiler installation is standard practice across most of Wiltshire.
- Supply is split between Wessex Water, Thames Water and Bristol Water depending on location, though all deliver hard water.
You have hard water — scale protection is worth having.
The World Health Organization notes that water at 200 mg/l or above will produce scale, and that is where this band begins. At this level limescale is a recurring cost rather than an occasional nuisance, and many boiler manufacturers require scale protection to keep the warranty valid. A softener is worth costing out properly.
