Kyiv takes its water mostly from the Desna and, to a lesser degree, the Dnipro, with artesian wells as a third source. The figure shown, 227.1 mg/L CaCO₃, is the median across 10 supply zones, which range from 185.1 to 250.2 mg/L, so it depends on which zone your street is in. Scale forms fast on heaters and fittings; a water softener is a common remedy.
DSanPiN 2.2.4-171-10 limit: 7 mmol/L (≈ 350 mg/L).

How Kyiv compares
- Tap water in Kyiv is close to the median of the 8 cities we track in Ukraine (2.26 mmol/L).
- By hardness it ranks 4 of 8 in Ukraine (1 = hardest); 57 % of these cities have softer water.
What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
Estimates for planning, not a quote. Check your appliance manual for exact settings.
