Wholesome drinking water enables life and is one of the basic requirements of a healthy living environment. As it is a very important public good, handling with sources of drinking water, its supply and ensuring wholesome drinking water is very strictly regulated by the Slovenian and European laws.
The requirements for drinking water are provided by the regulation Pravilnik o pitni vodi whichalso prescribes that internal control of drinking water must be established on the principles of HACCP system. HACCP is a preventive system that enables the identification of risks and critical control points and is providing a proper response to any existing risk factor.
I examined the HACCP study of the water supply system Cerknica - Rakek, which is managed by JP Komunala Cerknica d.o.o.. I compared the irregularities identified by the
health inspector and the results of analysis of drinking water in the 5-year period. The comparison showed a high proportion of inadequate analyses on the raw water and the
maximum anomalies were identified in the risk analysis. This shows weakness of the HACCP study, where the risks have not been evaluated correctly, particulary not at the water source and in its hinterland.
Better defined risks at water sources and in hinterland, better control and effective corrective procedure can reduce percent of inadequate analyses on the raw water and the need of water treatment before distribution to users.
