Description

The project is a waste water collection and treatment investment covering a population of over 130 000 in three cities, Sosnowiec, Katowice and Mysłowice, all within the industrial agglomeration in Silesia, the most heavily industrialised region of Poland. The project is located in the catchment of the Biala Przemsza and Czarna Przemsza rivers. The southern districts of the Sosnowiec municipality, western districts of the Katowice municipality and almost the whole municipality of Mysłowice are not connected to a waste water system which meets the standards set by EC and Polish legislation. The waste water originating in these residential areas is discharged to the Bobrek and Czarna Przemsza rivers directly or after inadequate treatment generating a daily load of BOD of over 10 tonnes per day. The Czarna Przemsza river is effectively an open sewer crossing the city. The project includes two main elements: the construction of a main collector (the Bobrek collector) to connect large areas of the three cities to the existing Radocha II waste water treatment plant and the up-grading of the plant to ensure treatment in line with Polish and EU standards.

The Bobrek collector will take waste water from two areas within the city of Sosnowiec. Firstly, a number of districts with a population of 13 200 serviced at present by three small treatment plants which do not meet current treatment standards will be connected. Two waste water treatment plants (Porąbka and Kazimierz Ostrowy with total designed capacity of 24 000 p.e.) will be closed down and transformed to pumping stations and the inflow to these plants will be diverted via the Bobrek collector to the Radocha plant. A third small plant already been closed in 2002 and has been transformed into a pumping station. Rationalising the number of treatment plants will reduce future operating costs of the system. A second area with a population of 13 200 will be connected to the main collector. This area has inadequate local waste water treatment which discharges directly to the Bobrek river.

In addition, 31 000 residents of Katowice and 53 700 residents of Myslowice will be connected over time via the Bobrek collector to the waste water treatment plant. In a later phase, not covered by the current project, a further 12 5000 people in Sosnowiec connected to septic tanks at present will be provided with a new sewerage network linked to the main collector. Ultimately an area with a population of 132 000 will benefit from the Bobrek collector.

The construction of the collector will include 4 pumping stations, 12 908 m of gravity sewage and 2 359 m of pressure sewage. The collector will run for approximately 12 km along the Bobrek river starting at the Kazimerz-Ostrowy treatment plant which will be transformed into a pumping station. The next part of the collector will run for 3.5 km along the Czarna Przemsza river which separates Sosnowiec from Katowice and Myslowice to the Radocha II waste water treatment plant.

The Radocha plant uses mechanical and biological treatment and was put into operation in 2000. It has a treatment capacity of 165 000 m³/day which is far above current requirements and no more than about a quarter of available capacity is used. On completion of the project the capacity will be reduced to 80 000 m³/day and the treatment process will be upgraded (especially in respect of nitrogen removal) to comply with EU standards. Once the existing small treatment plants have been closed and areas with inadequate treatment have been connected, approximately 73% of the capacity of the up- graded plant will be used.

The upgrading measures include:

ƒ Installation of a fourth blower in the aeration tanks, ƒ Installation of control valves in two out of four aeration pipelines, ƒ Modernisation of primary and secondary clarifiers, ƒ Improvements in the aeration tanks in particular to improve the internal recirculation system, ƒ Activation of digestion units unused at present, ƒ Installation of sludge thickening equipment, ƒ Extension of the chemical dosing station for improved phosphorus removal, ƒ Adjustment of the primary and secondary pumping stations to cope with increased volumes of water, ƒ Installation of automatic control systems and improved electrical and ventilation systems .

Most of the waste water will come from households with commercial and industrial users amounting to 13% of the inflow, of which industry accounts for 8%. There are ten industrial companies connected to the plant, of which four are food manufacturers. All ten companies have pre-treatment. After construction of the Bobrek connector it expected that a further two industrial companies in Sosnowiec will be connected, both with pre-treatment facilities, and twenty additional industrial and institutional customers (hospitals, schools) that discharge household-type waste water. In Katowice one coal mine with pre-treatment will be connected and four hospitals, discharging household- type waste water but with pre-treatment. In Myslowice two industrial companies including one coal mine will be connected, both will have pre-treatment and two hospitals discharging household-type waste water but also with pre-treatment will also be connected. All of the existing companies connected to the system have agreements with the water company. This will apply also to the new connections.

Objectives

The overall objective of the project is to achieve compliance with the EC Directive 91/271/EEC on Urban Waste Water Treatment. In summary, the specific objectives of project are:

ƒ To greatly improve the quality of water of the Biala Przemsza and Czerna Przemsza rivers, ƒ To increase the connection of the population within the catchment of the Radocha II treatment plan to a sewer system from 70% to 95%, ƒ To increase efficiency of the treatment process in the Radocha II WWTP, • To increase efficiency of the wastewater management system by rationalising the number of waste water treatment plants, ƒ To increase quality of life of inhabitants of Sosnowiec, Katowice and Mysłowice.

Environmental impact analysis

The type of infrastructure investment covered by the project does not fall within projects covered neither by Annex I nor Annex II of the EIA Directives (85/337/EEC, as amended by 97/11/EC). The relevant national authority issued a declaration confirming that the project will have no significant negative effects on the environment and is not situated in the environmentally sensitive area or close to its vicinity.

The relevant authority also issued a declaration confirming that the project has no effect on sites of nature conservation importance (Natura 2000 potential sites)
