Tap water in Zaporizhzhya is treated at two Dnipro water stations, DVS-1 and DVS-2, run by KP Zaporizhzhyavodokanal. The September 2026 monthly report gives total hardness of 3.65 mmol/L after DVS-1 and 3.00 mmol/L after DVS-2, both inside the printed norm of 1.5 to 7.0 mmol/L. The report does not say which districts each station serves, so the figure at your tap may sit anywhere in that range. Scale builds up in kettles and boilers at either level.
DSanPiN 2.2.4-171-10 limit: 7 mmol/L (≈ 350 mg/L).

Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
