This figure is over 3 years old; hardness may have changed.

Sabaudia is in the southern Lazio area run by Acqualatina, whose network draws on springs and wells (for the Gaeta area, for example, the Capodacqua wells and the Mazzoccolo springs); limestone ranges around the plain explain the mineral content. The published value is 378.0 mg/L CaCO₃, which counts as very hard water (a 2020 figure that may have changed since). Limescale builds up quickly on heating elements and taps, so a softener or regular descaling is worth considering.

Italian utilities report °f (French degrees); D.Lgs. 31/2001 recommends 15–50 °f.
