11 PROGRAMS FOR WATER INDUSTRY FINALYSED PROGRAMS MUNICIPAL UTILITIES DEVELOPMENT PROGRAM (MUDP) MUDP -I mil. Euro Rehabilitation of the water and wastewater infrastructure in 5 towns: Brasov, Craiova, Iasi, Timisoara; MUDP 54.3 Rehabilitation of the water supply systems in the Jiu Valley; MUDP -II mil. Euro Rehabilitation of the water and wastewater infrastructure in 10 towns: Arad, Bacau, Bistrita, Botosani, Braila, Cluj, Constanta, Focsani, Orada, Targoviste.

13 PROGRAMS FOR WATER INDUSTRY ON-GOING PROGRAMS INSTRUMENT STRUCTURAL FOR POLICIES FOR PRE-ACCESION ISPA Aims: - Rehabilitation of the environmental and roads sectors; - Connection to the trans-european corridors; - Policies and procedures for Structural and Cohesion Funds; Financing sources: - European Union (60 75%); - Local Budgets through EIB of EBRD loans (40 25%); Rehabilitation of the water supply and wastewater systems: Arad, Buzău, Brăila, Braşov, Cluj-Napoca, Constanţa, Craiova, Focşani, Iaşi, Oradea, Timişoara, Paşcani, Pitesti, Satu-Mare, Sibiu, Piatra-Neamţ, Târgu-Mureş, Valea Jiului; Aproved funds: 680 mil. Euro.

14 PROGRAMS FOR WATER INDUSTRY ON-GOING PROGRAMS SAPARD - PROGRAM FOR RURAL DEVELOPMENT Aims: - Extensions of the water supply systems in villages; - Extension of the wastewater systems in villages; - Nes water and wastewater works in rural area; Funding: - European Union (60 75%); - Local Budgets through EIB of EBRD loans (40 25%); Rehabilitation of the water supply and wastewater systems: Arad, Buzău, Brăila, Braşov, Cluj-Napoca, Constanţa, Craiova, Focşani, Iaşi, Oradea, Timişoara, Paşcani, Pitesti, Satu-Mare, Sibiu, Piatra-Neamţ, Târgu-Mureş, Valea Jiului; Aproved funds: 55 mil. Euro (only for water and wastewater).

15 PROGRAMS FOR WATER INDUSTRY ON-GOING PROGRAMS PROGRAM FOR WATER SUPPLY FOR VILLAGES Total estimated cost: 34.0 mil. Euro; Financing sources: LOCAL AND CENTRAL BUDGET; Target: 109 villages. PROGRAM FOR RURAL DEVELOPMENT Total estimated cost: 40.0 mil. Euro; Financing sources: Loan from the IBRD; Target: Different villages from 5 counties.

16 PROGRAMS FOR WATER INDUSTRY ON-GOING PROGRAMS SMALL AND MEDIUM TOWNS INFRASTRUCTURE DEVELOPMENT SAMTID Motivation: 230 small and medium towns in which are living 6.0 mil. people are not financially viable regarding the water and wastewater supply systems; Aim: Rehabilitation of the water and wastewater infrastructure to be operated by a regional, viable operator; Estimated cost: 380 mil. Euro; - 50% loan from EIB or EBRD; - 50% Phare through the National Cohesion Fund; Conditionality: Local Authorities will prepare the Feasibility studies.

17 FUNDAMENTAL STEPS REHABILITATION OF A WTP IDENTIFICATION OF THE DOMINANT PARAMETERS OF THE RAW WATER SOURCE; COMPATIBILITY OF THE CHEMICALS TO THE RAW WATER MATRIX; IDENTIFICATION OF THE WEAK POINTS OF THE TREATMENT SCHEME; IDENTIFICATION OF THE MOST APPROPRIATE TECHNOLOGY; PROPOSALS FOR REHABILITATION. STUDY ON PILOT PLANT
