Fužine is located in the region of Gorski Kotar, where Switzerland and Croatia intend to implement three water supply and wastewater projects. The uncontrolled discharge of untreated sanitary wastewater risks to pollute drinking water sources and catchment areas of the Danube and the Adriatic Sea. Moreover, the existing drinking water systems are in need of maintenance. A feasibility study, also financed through the Swiss contribution to Croatia, detects deficiencies and defines needs for action.

The benefitting municipality of Fužine is located in the region of Gorski Kotar in the north-west of Croatia between the Capital Zagreb and the coastal city Rijeka. Roughly 2,500 inhabitants are currently living in Fužine and its surroundings. The region is sparsely populated and mountainous.

Although 94% of the households have access to the public water supply system and are provided with drinking water of good quality, the current infrastructure is in need of improvement. The main deficiencies are a lack of water supply continuity, an unreliable pressure in the water supply system and a risk of pollution because of worn-out and corrosive installations. These deficiencies are leading to an unsatisfying service quality. Today, the water loss rate of the region is estimated at 52%.

As per 2015, the sanitary wastewater of 7% of the households of Fužine and its surroundings was collected in a sewerage system and treated adequately in a treatment plant. Still, a vast amount of sanitary wastewater is either discharged uncontrolled into nature or has to be collected individually and treated at high cost elsewhere.

  • Contribution to the environmental protection of the groundwater and surface water in the Adriatic basin
