Silesian city seeks EU-standard wastewater and drinking water

The city of Jaworzno in southern Poland is busy developing its water supply and wastewater services in a two-phase investment programme.

The first of two projects covers the construction of 86 km of sewage network, so that more than 80 % of inhabitants will be able to access it. Drinking water supplies will also be secured by developing an alternative source.

Limited sewage access

Located in the eastern part of Silesia province, around 20 km south-east of Katowice, the city of Jaworzno has a population of some 95 600. Currently only 72 % of the city’s population is connected to the sewage network.

This four-year project aims to extend the sewage network. It will also develop an alternative water source to replace an existing external source, thus securing and decreasing the cost of producing drinking water for the city. Additional work will eliminate the discharge of raw sewage from the Szczakowa district, thanks to the construction of pressure sewers and a canal transporting sewage to the drainage area for the Jaworzno-Dąb wastewater treatment plant (WTP).

A WTP is to be built at the Piaskownia water intake on the Central Canal, the main pipeline linking the plant to the city’s water-supply network. After implementation of the project, sewage from Jaworzno Municipality will be transported to the existing Jaworzno-Dąb WTP.

Extensive new system

As a result of this project, around 75 840 inhabitants in Jaworzno Municipality will be connected to the sewage system – a 10 % increase. The collective sewage system’s coverage rate will be expanded by around 12 %, to a population equivalent (p.e.) of almost 94 %. Furthermore, the area’s sewage treatment plant will be able to handle a contaminants input seven times greater than before. Altogether, this work is expected to clean up groundwater resources and ensure they are better managed.

Drinking water sourced from local reservoirs will be increased by about 40 %. This will improve its quality, while ensuring a more diverse and continuous supply.

Work in a separate follow-up project, which by contrast will not be part-funded by the EU, is to focus on extending the sewage network coverage around the city. Phase one and phase two projects are intended to ensure the compliance of Jaworzno’s wastewater treatment with the EU’s Urban Wastewater Directive.

Total and EU funding

The project “Modernisation and expansion of the sewerage system in the city of Jaworzno – phase I” has a total eligible budget of EUR 49 552 200, with the EU’s Cohesion Fund contributing EUR 32 570 900 for the 2007 to 2013 programming period.
