The Integration of Small Waterworks into Public Water Supply Systems in Croatia

According to official data, about 87% of the population in Croatia are supplied with water through public water supply systems. The rest of the population is supplied from individual water supplies or small (also called 'local') waterworks that supply 50 or more inhabitants (or deliver more than 10 cubic meters per day). These small waterworks are ordinarily managed by consumers who have also funded their construction. Water comes from sources that are not registered in the monitoring system by the national water agency, therefore these waterworks are characterized by the absence of a legal entity registered for providing water services and the lack of water permits and concessions granted by the national water agency, making them formally illegal. The problem of including small waterworks in the public water supply systems is complex with multiple factors involved. There are technical criteria that small waterworks must meet, but the problem is the lack of technical documentation, which is why the technical characteristics, such as water supply lines, profiles, lengths, etc., are not known. Water quality represent the greatest risk because water is supplied to consumers without any processing, often even without disinfection. This paper presents problems and possible solutions for including small waterworks into public water supply.
