Drinking water on the island of Krk: origin, quality and important tips for holidaymakers
The drinking water on the island of Krk is a true natural wonder in the middle of the Adriatic. While many neighbouring islands depend on water deliveries from the mainland in summer, Krk remains a self-sufficient water paradise. In this article you’ll find out everything about its origin, its excellent quality and what holidaymakers should bear in mind when using cisterns, so your stay on the “golden island” stays carefree.
The secret behind Krk’s drinking water supply
The self-sufficient supply of drinking water on the island of Krk is due to the special geology. The karst landscape acts as a huge natural filter and reservoir. Rainwater collects in underground aquifers and re-emerges as pure spring water.
- Ponikve, the lifeline: Lake Ponikve is the heart of the water supply. Together with the local streams, it ensures the availability of drinking water even in extremely dry months.
- Independence: Thanks to these resources, the island doesn’t depend on expensive pipelines from the Croatian mainland, which greatly strengthens the sustainability of tourism.
