Conclusions - ZaključciSignificant beneficial impact No potential risks to public healthGood design and construction practice = no unacceptable environmental impact

Koristan učinak je znacajanBez projekta = veliki nepovoljni uticaji na zdravlje ljudiDobro projektovanje i izvođenje – nema neprihvatljiv ekološki utjecaj


Best Practicable Environmental Option – integrated evaluation of sludge treatment and use / disposal optionsPriority is to identify sludge outlets that:

Recycle nutrients and organic matter on land (agriculture, forestry, land reclamation)Recover energy (incineration, co-combustion)

Landfill disposal is the option of last resort

Sludge Management Strategic ApproachStrateški pristup upravljanju muljem

Najbolja izvodljiva ekološka opcija – integrisana evaluacija opcija za tretman mulja i njegovo korišćenje/odlaganjePriorit predstavlja identifikovanje upotrebe mulja kojom se postiže:

Recikliranje nutrienata I organskih materija na zemljištu(poljoprivreda, šumarstvo, obnavljanje zemljišta)Obnavljanje energije (spaljivanje, koinsineracija)

Odlaganje na deponiju je najmanje poželjna opcija

Operating financial resultOperativni finansijski rezultat

• In order to assess operating profitability of the company, bad debt costs have been estimated as difference between reported revenues and collected related amounts.•Kako bi utvrdili operativnu profitabilnost kompanije, izvršena je procena troškova rezervisanja na potraživanjima kao razlika između generisanih prihoda i odgovarajućih uporedivih iznosa naplate.

•It can be concluded that adjusted annual operating loss of the company is currently around KM 300-400 thousand. This is the additional amount needed in order for Vodovod to be able to cover all of its operating costs.•Može se zaključiti da korigovani operativni gubitak kompanije trenutno iznosi između KM 300-400 hiljada na godišnjem nivou. To predstavlja neophodan dodatni iznos sredstava kako bi Vodovod bio u mogućnosti da pokrije sve svoje tekuće operativne troškove.

•Vodovod is not able to finance significant CAPEX, while these activities are financed primarily by Municipality. •Vodovod nije u mogućnosti da finansira značajnija kapitalna ulaganja, pri čemu se finansiranje ovih aktivnosti vrši pre svega od strane Grada.

Operating prihodiOperativni prihodi

• Main operating revenues are generated through water-supply activities, which account for around 81% of total operating revenues. Wastewater segment generates only around 13% of operating revenues, due to lower tariffs and lower number of customers.•Ključni operativni prihodi se generišu od vodosnabdevanja koje predstavlja 81% ukupnih operativnih prihoda. Usluge kanalizacije generišu svega 13% operativnih prihoda, usled nižih cena i manjeg broja potrošača.

•Increase in operating revenues in 2011 and 1H2012 are mainly caused by increase in tariffs, and also by extension of water-supply network which increased number of customers.•Povećanje operativnih prihoda u 2011 i prvoj polovini 2012 godine je uglavnom uzrokovano povećanjem cena, kao i proširenjem sistema vodosnabdevanja što je dovelo do povećanja broja potrošača.

• Based on 2011 data, additional overall tariff increase of 20% would enable Vodovod to cover all current operating costs of the company. This is assuming all other things remain equal, including collection rate of 83%.•Na osnovu podataka iz 2011 godine, dodatno povećanje cena od 20% bi omogućilo Vodovodu da pokrije sve tekuće operativne troškove, pod pretpostavkom da svi ostali parametri ostanu nepromenjeni, uključujući stopu naplate od oko 83%.

•Future tariff levels should be used to cover OPEX, as well as to finance CAPEX maintenance and urgently needed investments in water and wastewater services.•Budući nivoi cena treba da se koriste za pokrivanje operativnih troškova, održavanje osnovnih sredstava, kao i za finansiranje hitno potrebnih investicija u oblasti vodosnabdevanja i otpadnih voda.


Operating costsOperativni rashodi

• Main company expenses are wages which represent around 63% of total operating costs. •Glavni trošak kompanije su zarade zaposlenih koje predstavljaju 63% ukupnih operativnih troškova.

•Net wages remained practically the same in past three years, while increase in total wages expense is due to increase in related taxes and contributions. •Neto zarade se praktično nisu menjale u zadnje tri godine, dok je porast ukupnih troškova zarada uzrokovan porastom poreza i doprinosa.•Material costs are also significant company expense and represent 22% of total operating costs. This is mainly caused by high electricity costs since water is pumped into the network.•Troškovi materijala su takođe značajni i predstavljaju 22% ukupnih operativnih troškova. Ovo je pre svega usled visokih troškova električne energije koji nastaju pumpanjem vode u distributivnu mrežu.

ObavezeLiabilities

• Inability to cover total operating costs leads to constant increase in liabilities of the company. Vodovod is not settling electricity bills in adequate manner which is the main reason for overall increase in liabilities.• Nemogućnost pokrivanja ukupnih operativnih troškova rezultira u konstantnom povećanju obaveza. Vodovod ne izmiruje adekvatno svoje obaveze po računima za struju što je osnovni razlog ukupnog povećanja obaveza.

•Key risk of the company is accumulated liabilities for electricity bills in total amount of KM 8.9 million. Vodovod and Municipality should immediately explore any possibilities for settling these liabilities in satisfactory manner or arranging repayment schedule.•Ključni rizik za kompaniju predstavljaju nagomilane obaveze za električnu energiju u ukupnom iznosu od KM 8.9 miliona. Vodovod i Grad bi trebalo da odmah istraže sve mogućnosti za regulisanje i/ili reprogramiranje ovihobaveza na zadovoljavajući način.•Other long-term liabilities represent debt for wages related taxes and contributions accumulated prior to 2007. Vodovod agreed with Tax Authorities to repay this debt over next 15 years, starting from 2013.•Ostale dugoročne obaveze predstavljaju dug za poreze i doprinose na zarade akumuliran u periodu pre 2007. Vodovod je sa Poreskom Upravom ugovorio otplatu ovog duga u narednih 15 godina počevši od 2013 godine.

Municipality is servicing all of its financial liabilities in timely manner,

and has no overdue liabilities.Grad servisira sve svoje finansijske obaveze na vreme, i nema dospelih

neplaćenih finansijskih obaveza.

Municipality has low level of debt and significant capacity for raising

additional financial loans.Grad ima nizak nivo zaduženosti i

značajan kapacitet za dodatno finansijsko zaduživanje.

In 2011, debt service represented10.8% of current revenues generated

in the previous year, which is significantly below legally allowed

amount of 18%.U 2011, servisiranje duga je

predstavljalo svega 10.8% redovnihprihoda iz prethodne godine, što je daleko ispod zakonski dozvoljenog

iznosa od 18%.


Municipality borrowing capacityMogućnost zaduživanja Grada

• If potential EIB loan in the amount of KM 15.75 million is included, debt service would be highest in 2021 when it would represent 11.2% of current revenues generated in 2011.• Uključujući potencijalni EIB kredit od KM 15.75 miliona, servisiranje duga bi bilo najviše u 2021 godini kada bi iznosilo 11.2% redovnih prihoda iz 2011 godine.

• Municipality originally estimated that EIB loan for the project would be KM 15.75 million. However, Municipality has significant capacity for raising additional debt above that level, and there would be no legal constraints if final financing structure includes higher EIB loan then initially estimated. Maximum borrowing capacity, assuming EIB loan terms, is KM 34 million.• Prvobitna procena Grada je bila da će za ovaj projekat biti potreban EIB kredit u iznosu od KM 15.75 miliona. Međutim, Grad poseduje značajan kapacitet za dodatno zaduživanje iznad tog nivoa, tako da neće biti zakonskih prepreka ukoliko konačna finansijska struktura bude uključivala veći iznos EIB kredita nego što je prvobitno procenjeno. Maksimalni zakonski kapacitet zaduživanja Grada, pretpostavljajući uslove kreditiranja EIB-a, iznosi KM 34 miliona.

Financial Analysis – Key Findings and Issues Finansijska analiza – Ključni zaključci i pitanja

• Real and inflation linked tariff increases are needed and services remain affordable

• Vodovod is financially sustainable, meeting all debt financing needs and operating costs

• Funding issues – availability of local and international finance

• Potrebna su određena realna povećanja tarifa (iznad stope inflacije) ali da pri tome usluge ostanu priuštive

• Vodovod je finansijski održiv, ispunjava sve obaveze otplaćivanja duga i pokriva operativne troškove

• Sporna pitanja finansiranja – dostupnost investicija na lokalnom i međunarodnom nivou
