Vinhedo is supplied by a local operator; the sources checked do not name its intake. Records for 2025 give a median of 44.8 mg/L CaCO₃, with individual results from 28.2 to 93.4 mg/L. Limescale is rarely a problem at this level, and descaling the kettle is seldom necessary.
Portaria GM/MS nº 888/2021 sets a maximum of 300 mg/L CaCO₃ for total hardness (dureza total); operators report it in mg/L to SISAGUA.
