Main objectives of the Measure in Suceava County are:
Increasing of service coverage of awter supply system from at present 75% to approximately 85%;
The connection of 13.000 inhabitants from the districts Burdujeni and Itcani to the sewerage system;
The Rehabilitation of the used waters cleaning plant according to the standards of the Urban Wastewater Treatment Directive 91/271/CCE.
The Contract no. ISPA 2005/RO/16/P/PE/004-02 "Water Supply Facilities (including reservoirs, pumping stations, well field rehabilitations and transmission main)"
Improved quality of water supply
The water supply is currently extracted from two different sources: the Berchisesti well field and the Mihoveni Water Treatment Plant (treating extracted water from Suceava river).
In this respect the following elements will be included in this measure:
- regeneration and rehabilitation of 45 well fields in Berchisesti, disinfection unit, regeneration of wells by adding PH neutral chemicals, installation of new electrical equipment and the acquisition of a generator to avoid the interruption of water supply due to power cuts
- rehabilitation of the transmission mains running from Berchisesti to Suceava, incl. provision of bulk water meters at branches and rehabilitation of pressure break tank (Corlata) in order to assure safe water supply of the city from the well field;
- implementation of a central laboratory at the Reservoir Sf. Ilie in order to enable proper analysis of the water.
Improved Efficiency of Water Supply
The ISPA measure aims to increase the efficiency or water operation by reducing energy costs through reorganization of the network in clear defined pressure zones and refurbishment of outworn equipment, furthermore by reducing losses and extending the water supply coverage. In this respect the following elements will be included in this measure:
- rehabilitation of five water Reservoirs including installation of new valves, equipment and pipes in order to guarantee a proper maintenance/cleaning of the reservoirs;
- construction of a pressure reducing valve in district Zamca;
- construction of a new small sized water reservoir (500m³) in order to supply the presently non-served district Burdujeni by gravity;
- installation of new bulk water meters, new electrical equipment, control systems and of chlorination units at reservoirs and pumping stations to guarantee a better operation and control;
- abandon of three pumping stations and rehabilitation of two new pumping stations to guarantee a safer supply adopted to the new water demand and to reduce running costs;
- construction of two small-sized pumping stations in order to supply a higher elevated area from the district Burdujeni;
- replacement of around 12 km water network in order to reduce the high pressure zones;
- rehabilitation of around 14 km pipes with frequently bursts including service connection and water meters to improve security of supply;
- increase of service coverage from at present 75% to approximately 85% by around 22 km extension of pipe works ( including service lines).
The contract no. ISPA 2005/RO/16/P/PE/004-03 “Sewerage Facilities (including storage, overflow basins, pumping stations)"
The sewerage system in Suceava comprises currently of around 264 km mostly combined sewers. The infiltration level of around 47% is considerable high in particular due to high ground water table and to used sewer lines. Due to investments in the sewer system infiltration level can be reduced by around 10 - 15%. Besides this reduction of infiltration, the measure aims for an increase of service coverage from 65 to 75% and the improvement of the hydraulic capacity and performance of the sewer lines (protection against flooding), as well as better operation and maintenance of the sewer network.
As a result, the main components of the rehabilitation of the sewerage system can be summarized as follows:
- cleaning and TV inspection of sewer lines in order to stream line maintenance of the sewer network as well as cleaning and removal of settlements of around 22 km pipes;
- replacement of around 23 km damaged or undersized sewer lines and manholes and extension of around 10 km new sewer lines in areas without existing sewer network ( especially in district Burdujeni);
- rehabilitation of one existing wastewater pumping station ( Mirauti);
- construction of two basins for the storage of overflow from the sewer networks (construction of two retention basins of around 10.000 m³ total capacity in district Burdujeni and the zone Mirauti).
The contract no. ISPA 2005/RO/16/P/PE/004-04 “Wastewater Treatment Plant”
The Wastewater Treatment Plant is situated on left side of Suceava River.
The Wastewater Treatment Plant is oversized for the future needs of Suceava, the existing equipment has a low treatment efficiency and uses a high amount of energy.
The new Wastewater Treatment Plant will generate an amount of 6200 tons stabilized and dewatered sludge per year which can either be reused in the nutrient cycle or disposed in a sanitary landfill which will be built from cohesion fund investments.
Taking into account reduction of water consumption, the Wastewater Treatment Plant will be rehabilitated estimating an average of dry weather flow of 28.319 m³/day (i.e. 328 l/s). In terms of biological load, the plant will be rehabilitated for some 140.000 P.E. (population equivalent) composed of 84.000 P.E. from domestic consumers, 40.000 P.E. (ca. 30%) from industry and 16.000 P.E. (ca. 11%) from commercial agent.
The rehabilitated Wastewater Treatment Plant will achieve the standards set by European Union Directive for water waste treatment and discharge of sensitive water body (tertiary treatment – denitrification and chemical and biological phosphorous treatment).
The Wastewater Treatment Plant will beneficiate from modern supervisory control and data acquisition equipment (SCADA), which will also cover the sewage pumping stations.
