Anguillara Sabazia is in the Acea Ato 2 service area, where most of the supply is Apennine spring water carried by aqueducts from the Rieti area, topped up with local sources; we have not confirmed which intake feeds Anguillara Sabazia itself. Published analyses give a typical value of 242.6 mg/L CaCO₃, with readings from 238.8 to 246.5 mg/L, which counts as very hard water. Expect scale on kettles, shower heads and in the water heater, and descaling about as often as a hard-water kitchen requires.
Italian utilities report °f (French degrees); D.Lgs. 31/2001 recommends 15–50 °f.
