  1. Introduction Pljevlja Water and Wastewater Services Development Project Feasibility Study – June 2007 Funded by European Commission Under The Danube Investment Support Facility Study Implemented by EIB

  2. Environmental Pressures in Pljevlje • Two open cast coal mines and their associated overburden areas; • A coal fired power station and an associated ash and slag landfill; • A wood processing works; • The use of coal for domestic heating; • Poor solid waste disposal practices; • Areas of derelict industry; • Incomplete wastewater collection system and lack of urban wastewater treatment.

  3. Pljevlja Water Supply System

  4. Characteristics of Supply Sources Groundwater Surface Water The allocation of water from the Otilovici reservoir

  5. Unaccounted for Water Vodovod estimates for 2005 and 2006

  6. Problems with Water Supply Turbidity of karst sources after rainfall Potential pollution of Bezdan Spring High losses in distribution system and service connections Need for rehabilitation works on transmission mains Need for improved disinfection (Bezdan) High pumping costs Need for automation and SCADA system

  7. Industrial Wastewater Discharges

  8. Problems with Wastewater System Lack of treatment for urban and industrial wastewaters resulting in pollution of rivers Incomplete collection system Cross connection of wastewater and drainage networks Inadequate capacity for storm flows results in flooding Solid waste disposal exacerbates problems

  9. Examples

  10. Wastewater Collectors and Network

  11. Priority Investment Plan

  12. Project Benefits • Savings in Water Network Energy Use • Reduced Risks to Public Health • Environmental Benefits (river clean-up)

  17. Banja Luka Hot Water Leakage Prevention and Environmental Enhancement Project Sprečavanje isticanja tople vode u Banjoj Luci i Projekat unapređivanja zaštite životne sredine Studija izvodljivosti Studiju finansirala Evropska Komisija – Program pripreme projekta za zaštitu životne sredine za Zapadni Balkan Studiju izvršila EIB Banja Luka Hot Water Leakage Prevention and Environmental Enhancement Project Feasibility StudyStudy funded by European Commission – Environmental Project Preparation Facility for Western BalkansStudy Implemented by EIB 17 07/2007 Banja Luka

  18. Heat Supply Issues Problemi isporuke grijanja Veoma visoki gubici vode Visoki gubici toplotne energije te potrošnja električne struje Velika potrošnja goriva Vanjska i unutrašnja korozija u mrežama Unutrašnja korozija u kotlovima i podstanicama • Very high hot water losses • High heat losses and electricity consumption • High fuel consumption • External and internal corrosion in networks • Internal corrosion in boilers and substations 18 07/2007 Banja Luka

  19. Benefits of ProjectKoristi od projekta Lower Operating Costs Fuel savings Electricity and water savings Less maintenance and repair Cheaper operation Reduced risks to health Reduced water, air and soil pollution Better customer comfort Adequate heat supply Based on actual heat demand Niži operativni troškovi Ušteda goriva Ušteda elektr. energije i vode Manje održavanja i popravljanja Jeftinije poslovanje Povećana zaštita zdravlja Smanjene zagađivanja vode, vazduha i zemljišta Veća udobnost kupaca Odgovarajuća isporuka grijanja Zasnovana na stvarnoj potražnji za grijanjem 19 07/2007 Banja Luka

  21. Bosanski Petrovaci Rekonstrukcija kanalizacionog sistema u Bosanskom Petrovcu. Studija izvodljivosti Prezentacija 2008.Godine Studiju finansirala Evropska Komisija u okviru Pripreme projekta za zaštitu životne sredine za Zapadni Balkan Studiju implementirala EIB Bosanski Petrovac Wastewater ImprovementsFeasibility StudyPresentation January 2008 Study funded by European Commission under the Environmental Project Preparation Facility for Western Balkans Study Implemented by EIB 21

  22. Existing sources of waterPostojeća izvorišta vode • Smoljani Springs • Sanica Source • Water quality • High energy requirements for Sanica • Losses • Izvorište Smoljana • Izvorište Sanica • Kvalitet vode • Više energetske potrebe za Sanicu • Gubici 22

  23. Bosanski Petrovac- Present SituationBosanski Petrovac- Postojeće stanje 23 Central Area largely served by combined sewers. Leakage from old sewers causing pollution. Western area served by combination of septic tanks and direct discharge to land. Eastern area largely served by septic tanks. No wastewater treatment facilities. Centralna zona uglavnom se sastoji od kombinovane kanalizacione mreže. Curenja iz starih kanalizacionih odvoda što uzrokuje zagađenje. Zapadna zona se sastoji od kombinacije septičkih jama i direktnog ispusta na zemljište. Istočna zona uglavnom se služi septičkim jamama. Ne postoje postrojenja za tretman otpadnih voda.

  25. Priority Project – Possible CasesPrioritetni projekat- Moguće situacije 2007 prices including Engineering and physical contingencies but excluding VAT 2007 Cijene uklučujući tehničke i fizičke eventualnosti bez PDV-a

  26. Velika Kladusa Rekonstrukcija kanalizacionog sistema u Velikoj Kladusi. Studija izvodljivosti Prezentacija 2008. mart Studiju finansirala Evropska Komisija u okviru Pripreme projekta za zaštitu životne sredine za Zapadni Balkan Studiju implementirala EIB Velika Kladusa Wastewater ImprovementsFeasibility StudyPresentation March 2008 Study funded by European Commission under the Environmental Project Preparation Facility for Western Balkans Study Implemented by EIB March 2008 26 26

  27. Water SupplyVodosnadbijevanje March 2008 27 27 • Source capacity greater than demand • 98% Water supply coverage • Main remaining concerns: • Water quality & Chlorination • Non-revenue water • Kapaciteti izvora veci nego zahtjevi • 98% pokrivenosti sa vodosnadbijevanjem • Preostali glavni problemi • Kvalitet vode & klorinacija • Neprofitabilna voda

  28. Present SituationSadasnja situacija Untreated wastewater discharges polluting Grabarska, Kladusnica and Glina Rivers Old leaking sewers in central area polluting groundwater Septic tank discharges in remaining areas also polluting groundwater Nepreciscena otpadna voda izlijeva se i zagadjuje rijeke Grabarsku, Kladusnicu, i Glinu Stari kanalizacioni sistem u centru ispusta kanalizaciju i zagadjuje podzemene vode. Izlijevi iz septickih jama zagadjuju podzemne vode. 28

  29. Proposed New Sewers in Velika KladusaPredlozenanova kanalizacijska mreza u Velikoj Kladusi WWTP Site –Pogon za preciscavanje otpadnih voda Secondary wastewater and rainwater sewers for central area Sekundarna kanalizacijska mreza za otpadnu i oborinsku vodu u centralnom dijelu Collector A – kolektor A Collector B –kolektor B Secondary wastewater and rainwater sewers for industrial area Sekundarna kanalizacijska mreza za otpadnu i oborinsku vodu u industrijskom dijelu March 2008 29

  31. ConclusionsZakljucak March 2008 31 31 Good design and construction practices - no unacceptable environmental impact Significant beneficial impact No project = significant adverse risks to public health Dobro projektovanje i konstrukcija – nema ekoloski uticaj Koristan ucinak je znacajan Bez projekta = nepovoljani rizici za opce zdravlje su veliki
