Abstract:K identifikaciji problematike varstva okolja je v začetnih fazah pristopila že Vlada Republike Slovenije, ki je v sprejetih dokumentih, med drugimi tudi v Nacionalnem programu varstva okolja in v Operativnem programu razvoja okoljske in prometne infrastrukture 2007–2013, že začrtala smernice za obvladovanje problematike razmerij med naravo in družbo, prav tako pa tudi oskrbe s pitno vodo. Problematika oskrbe s pitno vodo v Pomurski regiji se odraža predvsem na področjih neustrezne zaščite vodnih virov in zajetij podzemne vode, na nerazviti javni vodooskrbi, ki ne omogoča oskrbe celotnega prebivalstva s pitno vodo, kot tudi z nezadostnimi zmogljivostmi zagotavljanja varne in kakovostne oskrbe z vodo. K reševanju problematike je Vlada Republike Slovenije pristopila s projektom vzpostavitve novega neodvisnega regionalnega vodnega sistema, katerega poglavitni cilj je zagotovitev trajnostne, nemotene in kakovostne oskrbe s pitno vodo vsem prebivalcem Pomurja. Za zagotovitev ustrezne oskrbe s pitno vodo je treba vzpostaviti oziroma zgraditi potrebno infrastrukturo, ki zajema vodne vire s črpališči, zajetji in čistilnimi napravami, transportne vodovode, primarne ter sekundarne vodovode. Zaradi enormnega obsega potrebne infrastrukture in njenih investicijskih vrednosti se je projekt izvedbe celotnega sistema oskrbe s pitno vodo razdelil v dve obdobno ločeni fazi. Lastništvo nad infrastrukturo transportnega tipa, ki vključuje vodne vire, transportne in skupne vodovode, bo med občinami razdeljeno po določenem ključu. Glede na delež lastništva nad infrastrukturo transportnega tipa bodo občine morale zagotavljati sredstva za njeno vzdrževanje oziroma pokrivati stroške amortizacije te infrastrukture. K tem stroškom je treba prišteti še stroške vzdrževanja oziroma amortizacije primarnih in sekundarnih vodovodov, torej infrastrukture primarnega tipa, ki jih bodo občine krile individualno, in sicer v okviru svojih meja. Vsota teh stroškov se bo odražala v višini omrežnine kot delu cene pitne vode v posamezni občini. Glede na dve obdobno ločeni fazi izvedbe investicije bo tudi končna cena pitne vode naraščala skladno s stopnjo realizacije investicij. Tako lastništvo, strošek amortizacije infrastrukture transportnega tipa kot tudi višino omrežnine za posamezno občino smo izračunavali po treh ključih: D. število vodomerov v posamezni občini (predvideni števci so pokazatelj porabe vode in s tem uporabe infrastrukture), E. število prebivalstva v posamezni občini (število prebivalstva je pokazatelj porabe vode in s tem uporabe infrastrukture), F. predvidena poraba vode v posamezni občini v letu 2056 (predvidena količina porabljene vode (v l/s) je pokazatelj uporabe infrastrukture). Strošek amortizacije infrastrukture primarnega tipa se ne spreminja, in to ne glede na uporabljen način izračuna, saj je lastniški delež oziroma investicija posamezne občine vedno enaka. Rezultati izračunov so različni in glede na že v sklepnem delu predstavljeno dejstvo, torej da lahko porabo vode v prihodnosti le predvidimo, tako kot lahko le predvidimo tudi porast oziroma padec prebivalstva in njuna nihanja, je pri izračunu omrežnine transporta verjetno najbolj smiselno in realno uporabiti princip izračuna glede na število vodomerov, saj informacije o številu vodomerov v posamezni občini izhajajo tudi iz dejanske instalirane moči. Ker je omrežnina le del cene pitne vode in ker smo pri podanih izračunih omrežnine zajeli le stroške amortizacije predvidene infrastrukture, je z vidika cene pitne vode treba upoštevati še dodaten dvig končne cene pitne vode za končnega porabnika, saj le-ta vključuje tudi vodarino in vodna povračila.

Title:POTABLE WATER SUPPLY ON THE AREA OF MUNICIPALITIES OF SYSTEM B IN POMURJE - ESTIMATION OF NETWORK CHARGES AS PART OF POTABLE WATER PRICE
Abstract:Identification of the environmental protection problematic was one of the main priorities of the Government of Republic of Slovenia (in following text: Government of RS). The directives for controlling problems between nature and society as also Potable water supply were indicated by the Government of RS in the National Environment Protection Action Program documents and Operational Program of Environmental and Transport Infrastructure Development. The potable water supply problematic on the Pomurje region is reflected in the inadequate protection of water wells and ground water reservoirs, insufficient public water supply which does not provide enough water for the total population, as well as insufficient capacity to ensure safe and quality water supply. Government of RS approached to these problems with a project to establish a new and independent regional water supply system of which the priority objective is to ensure sustainable, stable and quality water supply system for all inhabitants of Pomurje region. To assure a suitable supply of potable water it is necessary to build an adequate infrastructure which includes water wells with pumping stations, treatment plants, transport waterworks, primary and secondary waterworks. Due to the enormous extents of required infrastructure, realization of the project was divided into two periodically separate phases. Ownership over the infrastructure of transport type, that includes water wells, transport and total waterworks, will be divided among municipalities according to a specified key. Proportionally to the individual ownership over the transport infrastructure, each municipality will have to assure financial means to cover the amortization costs of the infrastructure. To this costs, the cost of maintenance and amortization of the primary and secondary waterworks and facilities should be added. Municipalities will cover amortization costs of primary infrastructure individually according to the municipal borders. The sum of all costs will be reflected inside the network charges, as part of the potable water price of the individual municipality. And regarding to the two separated stages of investment realization, the final price of potable water will rise according to the investment realization rate. Ownership, as also amortization costs of transport type infrastructure and the amount of network charges for individual municipality were calculated according to three different keys: A. Number of all water gauges in the individual municipality (predicted number of water gauges indicates water consumption and therefor the use of the infrastructure) B. Population number in the individual municipality (Population number indicates water consumption and therefor the use of the infrastructure) C. Predicted water use in the individual municipality in the year 2056 (Predicted water consumption (in liter per second (l/s)) indicates the use of the infrastructure) The amortization cost of the primary infrastructure does not change regardless to the calculation method, because the ownership share or investment of individual municipality is always the same. Calculation results are different and regarding the already presented fact, that the future water consumption as well as population oscillation can only be predicted and not assured, the most sensible and realistic calculating method would be to consider the number of water gauges. The information on the number of water gauges in each municipality stem from the actual installed capacity. We calculated only amortization of the foreseen infrastructure that is only a part of network charge. And network charge is only part of potable water price. To calculate final price of potable water for the end user, we have to consider also water rate and water refunds.
