Most drinking water in Sardinia comes from artificial reservoirs and is treated by Abbanoa before distribution, which is true of Nuoro too. Published analyses give a typical value of 32.3 mg/L CaCO₃, with readings from 28.3 to 42.5 mg/L, which counts as soft water. Scale is a minor problem here, and detergent doses can be kept low.
Italian utilities report °f (French degrees); D.Lgs. 31/2001 recommends 15–50 °f.
