Water Supply and Wastewater of the municipality of Delnice
Delnice is located in the region of Gorski Kotar, where Switzerland and Croatia 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 Delnice is located in the region of Gorski Kotar in the north-west of Croatia between the Capital Zagreb and the coastal city Rijeka. Roughly 5,000 inhabitants are currently living in Delnice and its surroundings, which makes it Gorski Kotar’s main town. The region is sparsely populated and mountainous.
Although 86% 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 44% of the households of Delnice 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.
