Source of Water in Ostrava, Czechia

Tap water in Ostrava mainly comes from surface water reservoirs in the Moravskoslezský kraj, especially Kružberk on the Moravice River and Šance on the Ostravice River. These reservoirs collect water from the surrounding Beskydy and Nízký Jeseník uplands.

The raw water is treated at regional water-treatment plants, including Podhradí and Ostrava-Nová Ves, before entering Ostrava’s distribution network. Treatment removes particles and microorganisms, and the water is routinely monitored to meet Czech drinking-water standards.

Ostrava Drinking Fountains

Public drinking fountains supplied by the municipal water network in Ostrava are generally safe to use and must meet Czech and European drinking-water standards. Use fountains clearly marked as drinking water.

Avoid any fountain displaying a maintenance or non-potable-water notice, or one with visibly dirty fixtures or stagnant water. Let the water run briefly before drinking, especially during warm weather or after the fountain has been unused.
