Požega is supplied by Tekija d.o.o. from groundwater intakes. The figures here are raw-water values from the utility's intake table, not tap measurements: 268 mg/L in the Luke zone and 411 mg/L in the Zapadno polje zone, a median of 339 mg/L. The table carries no sample date, so 2026 is the year of the page. Which zone serves your address decides which figure applies, so ask the utility before sizing a softener.
Croatian suppliers report total hardness in mg/L CaCO₃ or °dH.
