1 STANDARD SUMMARY PROJECT FICHE: PROJECT PL Project Title: Extension of Waste Water Treatment Plant (WWTP) of Wroclaw Sub-programme: Environment Location: Wroclaw Objectives: The proposed project lies within the programme priority area of water pollution as its development is to improve the water quality of the Odra River and reduce the pollution load on the Baltic Sea caused by the city of Wroclaw. Specifically the project objectives are as follows: Meeting the EU Directives standards with regard to accession requirements. Wroclaw is a city with a population of 642,000 inhabitants and in order to meet the EU Directives it must have a WWTP meeting the standards according to those which will be in force in Poland after the year These standards require treatment to effluent quality parameters similar to those in force in the EU, including BOD 15 mg/l or less and total P 1.5 mg/l or less. This project will assist this objective, by increasing the volume of sewage that is treated. Fulfilment of the Helsinki Convention requirements liquidation of hot-spots. Wroclaw is included into the "hot spot" liquidation programme under Helsinki Convention. The construction of the WWTP will reduce the pollution load discharged into the Baltic Sea by the Odra River. At present, the mean base pollutant loads in raw sewage discharged to the Baltic by this River are as follows: LBOD = kg/d, LSS = kg/d, LTN = 4320 kg/d, LTP = 810 kg/d. Once the Wroclaw WWTP is in operation, mean pollutant loads in treated effluent discharged to the Baltic Sea will be as follows: LBOD = 1197 kg/d (18- fold reduction), LSS = 1800 kg/d (10-fold reduction), LTN = 2292 kg/d (twofold reduction), LTP = 135 kg/d (six-fold reduction). Description: The City of Wroclaw is located in the western part of Poland and has a population of 642,000 inhabitants. Wroclaw lies on the Odra River and is a major source of pollution draining to the Baltic Sea from this river. At present, the sewage network in Wroclaw receives 170,000 m 3 /day. The problem is that only a small part of the wastewater is treated mechanically (28,000 m 3 /day) and the major part of the wastewater is discharged to the Odra River untreated. Although the 1 st stage of the WWTP located at Janowska Street (built in 1996) has the capacity of 90,000 m 3 /day of mechanical primary treatment, only minor part of the existing sewage delivery system is connected to this WWTP directly. It is the aim of the 2 nd stage of the WWTP to extend the present plant by biological treatment with sludge management and to build the main sewer with pumping station to ensure the required volume of wastewater from the central municipal sewage catchment to the Wroclaw WWTP. Upon the completion of the extension, for which this project will provide equipment described below, the WWTP in Wroclaw will receive 90,000 m 3 /day of wastewater, including 7,000 m 3 /day of industrial wastewater, which forms about 4% of the total volume of wastewater. Before being discharged into the municipal sewage system, industrial effluent is treated in the preliminary cleaning procedures. As the integral part of this project, the construction of the main sewer with the Nowy Port intermediate pumping station will be developed. 1

2 The main sewer together with pumping station located in the northern part of the city will feed sewage from the central municipal sewage system to the Wroclaw WWTP. PHARE funding will assist in implementation of this component. It is proposed to finance construction of the intermediate pumping station of Nowy Port with ancillary facilities. Specifically PHARE funds will be used for funding of construction works, supply and installation of equipment necessary to make this facility fully operational. The facility will ensure that the Wroclaw WWTP receives a volume of sewage corresponding to its design capacity of 90,000 m 3 /d. Otherwise, capacity of the planned WWTP would not be fully utilised. The Wroclaw authorities have a complete documentation for implementation of the project on "Main sewage collector - pressure mains". This documentation consists of the engineering design and the required administrative decisions, including the planning permission. Institutional framework: Ministry of Environmental Protection, Natural Resources and Forestry / Commune of Wroclaw City Administration Office, Investment and Technical Department. Ownership of the WWTP facility will be with Commune of Wroclaw. Upon completion of the construction the main sewage collector with the pumping station will be handed over to the present operator of the Wroclaw WWTP, the Municipal Water Supply and Sewage System Enterprise Ltd. (MPWiK Sp. z o.o.). MPWiK Sp. z o.o. is a 100% municipality-owned limited liability company established by the City Council of Wroclaw for the purpose of serving the city s water and wastewater needs.

The National Fund and the Beneficiary will monitor project employment to ensure that this condition is being fully implemented. Environment: Environmental Impact Assessment of the facilities of the Wroclaw Wastewater Treatment Plant study was prepared by the Wameco company in April 1996 and is available at the Ministry of Environment in Poland. The evaluation concerns the facilities of the process line including the solid waste and sludge disposal site, where screenings, grits and sewage sludge, both raw and digested will be disposed of. The conclusions of the study are as follows: given the proposed land use in the vicinity of the Wroclaw Wastewater Treatment Plant, as per the local development plan, there will be no environmental hazard; there will be no residential development in the area; the type and quantities of pollutant emissions will not have an adverse impact on the environment (soil, plants, forests) situated within the range of the Wroclaw Wastewater Treatment Plant; favourable soil conditions and the adopted technological solutions for the solid waste and sludge disposal site disposal site ensure groundwater protection; the Wroclaw Wastewater Treatment Plant will not emit excessive odours. The designs will ensure achieving the required level of wastewater treatment, i.e.: BOD5-15 mg O 2 /dm3 and less total suspension - 30 mg/dm3 and less total nitrogen - 28,5 mg/dm3 and less total phosphorus - 1,5 mg/dm3 and less Envisaged environmental benefits: - intake of significant quantities of wastewater from the City, by the main sewer - delivery section, presently transported onto the irrigation fields, - relieving the irrigation fields and hence raising the level of wastewater treatment and reducing the noxious odours in that part of the City, - fines for environmental pollution no longer applicable, - limiting the load of pollution released into the Odra and onward into the Baltic (consecutive contribution of the Republic of Poland towards protection of sea water, in accordance with the Helsinki convention signed by the government, Wroclaw is recognised as the hot-spot program), - incentives for development of investments in Wroclaw. Final conclusion: The adopted technical solutions for the facilities of the Wroclaw Wastewater Treatment Plant minimise emissions of gases, odours, and microbiological pollutants from the Plant and will not impact adversely on the health of people living in the non-immediate neighbourhood. Rates of return: Until 2010 the rate of return is 0.92 % for the entire project if loan 3

4 repayment is taken into account. The calculation has been based on the assumed increase in wastewater quantity between 1998 and 2001 from 25,000 m3/day to the level of 90,000 m3/day. Investment criteria: The project proposal meets the general criteria for PHARE Investment Support.The PHARE support for this project will help to achieve the planned environmental benefits and ensure completion of the entire project well within scheduled time. PHARE input will mobilise funding from other sources needed for completion of the system. However it will not replace other financing sources such as IFIs and private sector. The WWTP extension project is well advanced. The City Administration Office of Wroclaw representing the Commune of Wroclaw, has a complete design documentation for the construction of the main sewage collector and pumping station prepared by the Design Office for Municipal Buildings, the water permit, separate construction permits for each structure, and other consents and approvals required for project implementation. Construction of a mechanical and biological WWTP with sludge management in Wroclaw will ensure wastewater treatment according to standards in force beyond an essential element in the process of Poland's integration with the EU. Wroclaw is included into the "hot spot" liquidation programme under Helsinki Convention - construction of the WWTP will reduce the pollution load discharged into the Baltic Sea by Odra River. The project meets accession requirements under the following Directives: 91/217/EEC concerning municipal wastewater; 76/160/EEC concerning the quality of water in bathing resorts; 76/464/EEC concerning pollution caused by certain hazardous substances discharged into the aquatic environment; 96/61/EEC IPPC. The beneficiary of this project will be the Commune of Wroclaw, represented by the City Council owner of the facility. The WWTP will be financially sustainable in long term perspective, deriving its revenue from fees for effluent treatment. All PHARE funded supplies will be processed in accordance with competition provisions of the Europe Agreements and PHARE rules for tendering and contracting. The contract for the construction will be awarded through the international competitive tender in accordance with the procedures established by the EU. Conditionality and sequencing: Cofinancing from the Government and other sources as proposed and completion of the project on schedule (by end 2000) Maintenance and pricing policy towards residents to ensure sustainability and renewal of the project s capacity in the medium term. Continued development of approximation and implementation strategies for the water sector. Continued development of project management and project preparation capacity within the ministry and the NFEP. 4

13 Annex 6 Reference to the Feasibility Study and the Environmental Impact Assesment FEASIBILITY STUDY for Waste Water Treatment Plant - Wroclaw Construction of the Wroclaw Wastewater Treatment Plant is an undertaking recorded for over 20 years in the economic strategy of Wroclaw, covering among others, realisation of wastewater disposal objects of the City. In the current environmental protection program of the Province of Wroclaw for the years , prepared by the Provincial Administration Office in Wroclaw, realisation of the wastewater treatment plant for the City forms one of the high priority items. The final capacity of the wastewater treatment plant takes into account the development prospects of the City and ensures in the future, the acceptance of wastewater from the whole area of the City. Realisation of the main sewer (Nowy Port intermediate pumping station and delivery pipeline) always formed the basic object in realisation of the Wroclaw Wastewater Treatment Plant, ensuring transport (transfer) of wastewater, presently discharged onto the Osobowickie irrigated fields. The main sewer will link the Stary Port intermediate pumping station located in the northern part of the City with the main sewer Odra, in operation. For realisation of the above object, the following will be constructed: - decompression chamber, - delivery pipeline o diameter 1.2 m and length about 2.7 km, - intermediate pumping station with two pumps (Nowy Port), - set of connections to the existing system, - 20 kv transformer and distribution station, and - facilities built for operation and adaptation of sand trap on the grating chamber. On the basis of the approved program conception, finalised was the route of the delivery pipeline, variant R and the basic technical parameters. The accepted technological and project designs enable intake of wastewater in quantity of m 3 /24h (with Q max = 5348 m 3 /h) including about m 3 /24h of industrial wastewater. Communal sewage will originate from housing estates in the city inhabited by about residents. The designs will ensure achieving the required level of wastewater treatment, i.e.: BOD5-15 mg O 2 /dm3 and less total suspension - 30 mg/dm3 and less total nitrogen - 28,5 mg/dm3 and less total phosphorus - 1,5 mg/dm3 and less Envisaged ecological effect: - intake of significant quantities of wastewater from the City, by the main sewer - delivery section, presently transported onto the Osobowickie irrigation fields, - relieving the Osobowickie irrigation fields and hence raising the level of wastewater treatment and reducing the noxious odours in that part of the City, - stopping the imposition of fines for environmental pollution, - limiting the charge of pollution released into the Odra River and onward into the Baltic (consecutive contribution of the Republic of Poland towards protection of sea water, in accordance with the Helsinki convention signed by the government, Wroclaw is covered by the hot-spot program), - this will enable development of building works and other investments in Wroclaw. Conclusions of the Report on Environmental Impact Assesment The Municipality has a study prepared in April 1996, entitled Environmental Impact Assessment of the Facilities of the Wroclaw Wastewater Treatment Plant, ref. WOS/61-912, which evaluates the environmental impact of the facilities of the Wroclaw Wastewater Treatment Plant. 13

14 The evaluation concerns the facilities of the process line including the solid waste and sludge disposal site, where screenings, grit from the grit chamber and sewage sludge, both raw and digested, will be disposed of. The conclusions of the study are as follows: a) Given the proposed land use in the vicinity of the Wroclaw Wastewater Treatment Plant, as per the local development plan, there will be no environmental hazard. There will be no residential development in the area. b) The type and quantities of pollutant emissions will not have an adverse impact on the environment (soil, plants, forests) situated within the range of the Wroclaw Wastewater Treatment Plant. c) Favourable soil conditions and the adopted technological solutions for the solid waste and sludge disposal site ensure groundwater protection. d) The Wroclaw Wastewater Treatment Plant will not emit excessive odours. Final conclusion The adopted technological solutions for the facilities of the Wroclaw Wastewater Treatment Plant minimise emissions of gases, effluents, odours, and microbiological pollutants from the Plant and will not impact adversely on the health of people living in the non-immediate neighbourhood. 14
