Challenges of municipal hygiene - the case of safe drinking water supply

V članku so na primeru zagotavljanja kakovostne oskrbe z zdravstveno ustrezno pitno vodo prikazani izzivi, ki jih pred sanitarne strokovnjake, ob odločanju o naložbah v komunalno infrastrukturo, postavlja povezava lokalne politike, lobijev, finančnih in zakonodajnih vplivov ter stališč stroke. Lastnica komunalne infrastrukture je običajno občina, upravljavec pa je tisti, ki mora zadostiti zahtevam glede skladnosti in zdravstvene ustreznosti pitne vode. Predstavljene so značilnosti vodovodnega sistema Postojna-Pivka, stanje sistema pred sanacijo, rezultati mikrobioloških preskušanj v obdobju med leti 2009 in 2014 ter uporabljene tehnološke rešitve ob sanaciji v letu 2012. Na osnovi zgoraj naštetega ter znanstvenih in strokovnih ugotovitev o posameznih dosegljivih tehnologijah, so predstavljeni izzivi stroke ob odločanju za izbor najustreznejše tehnologije ob predvideni investiciji v komunalno infrastrukturo.In the paper the case of the provision of safe drinking water supply is used to highlight the challenges put on sanitary experts in the decision-making process of investments in the municipal infrastructure, taking into consideration the links between local policy, lobbyists, financial and regulatory impact and professional decisions. The owner of the municipal infrastructure is usually the municipality, but the operator is the one who must ensure compliance of safe drinking water to meet the criteria. The characteristics of the water supply system Postojna-Pivka, system status before remediation, the microbiological tests results in the period between years 2009 and 2014, and applied technology solutions during remediation process in 2012, are presented.
