Major scheme to improve wastewater and sewerage services

A project to upgrade wastewater treatment and collection processes in the Polish city of Katowice will help to connect the majority of local people to the sewerage network. The scheme also brings the city’s wastewater management services into line with the requirements of Polish and European Union law.

Funding is provided for the modernisation of the Panewniki and Podlesie wastewater treatment plants, the upgrading of the sewerage network and improvements to storm water treatment systems.

The work programme includes:

  • construction of a new sewerage network in areas which have no wastewater system;

  • construction of a new storm water gravitational network;

  • restructuring the existing gravitational sewerage network;

  • building five storm water overflows and adapting sewerage systems for storm water drainage.

These physical works call for the construction of about 53 km of sewerage network and the renovation of an existing 13.8 km. About 6 km of storm water drainage network is to be built and about 4 km of the existing network is earmarked for restructuring.

Increasing plant capacity

Modernisation of the Panawniki wastewater treatment plant involves replacing old equipment. In addition, a sludge chamber is to be made operational and incorporated into the plant’s systems. The work will improve the efficiency of wastewater treatment and increase the plant’s capacity to process sewerage.

Similar work takes place at the Podlesie plant, where new equipment will be installed and a second sludge activation chamber brought on line. The modernisation programme also calls for the construction of a third sludge chamber and the replacement of aeration and mixing systems in all biological reactors. Again, the goal is to improve efficiency of wastewater processing while increasing capacity.

Overall project targets are to:

  • increase sewerage collection rates in Katowice from 77.65 % to 79.75% in 2015; and across the whole agglomeration from 82.07 % to 83.65 % in 2015.

  • increase sewerage network connection rates in the city from 78.35 % to 99.27 % in 2015; and across the whole agglomeration from 85.50 % to 99.51 % in 2015.

The construction of new sections of sewerage network connects 7 220 more residents to the system. In all, the restructuring means that 63 355 p.e. are connected to the network. (p.e. stands for population equivalent, a unit of measure to describe the size of wastewater discharge produced by a person, household or business every day). The work also benefits the natural environment by improving water and soil purity.

This scheme is a continuation of the comprehensive “Wastewater Management in Katowice” project, which was implemented as part of the city’s master plan to improve wastewater services. All the work for stage one of the wider project has been completed. As the next element of the wastewater management plan for Katowice, this scheme is seen as an integral but technically and financially separate entity in its own right.

It is estimated that the project will create 215 jobs during the implementation phase.


Total investment and EU funding

Total investment for the project “Water and sewage management in Katowice – Phase 21” is EUR 64 819 560, with the EU’s Cohesion Fund contributing EUR 30 468 579 for the 2007 to 2013 programming period. The project falls under the “Infrastructure and Environment” Operational Programme, priority “Water and sewerage management”.
