The Nagykanizsa and Agglomeration Sewerage Project will provide the necessary infrastructure improvements to bring the regions sewerage service fully back into the 21st century. In the long term the sewerage program will help protect the water supply of Nagykanizsa and the surrounding villages.

The aim main is to stop groundwater pollution underneath the geographical area of Nagykanizsa, raising the quality of life for the population, and to improve the environmental conditions for sustainable settlement development.

Expanding the infrastructure

The project consists primarily of the enlargement of the sewage network in Nagykanizsa, and the construction of new sewerage networks in 12 villages in the surrounding locale. These sewerage networks will be connected to the Nagykanizsa Waste-Water Treatment Plant, which will be upgraded. Sludge treatment and disposal systems will also be constructed. It is estimated that this project will allow access to the sewerage network to an additional 7 816 people in the population.

The sewerage network will be extended in Nagykanizsa and out to the twelve surrounding villages. Altogether 3 316 new household connections will be built and 163 km of new sewerage pipes laid, and 6 km of existing pipes reconstructed. The existing waste-water treatment plant at Nagykanizsa will be upgraded, to allow it to meet the discharge limit values in sensitive areas. A new septic waste receiving tank will also be constructed, along with a sludge treatment and disposal system which will include sludge thickening, ultrasonic pre-treatment, anaerobic mesophilic digestion, dewatering and composting. The purpose of which is to reduce the amount of organic matter and the number of disease-causing microorganisms present in the solids.

Improving the quality of life

The goal of the project is to provide better waste-water services to the population of Nagykanizsa and its environs, by increasing the number of people who have access to waste-water collection and treatment, improving the quality of life for the whole area. Groundwater pollution is expected to decrease due to the sewerage extension and reconstructions, and the improved quality of waste-water treatment provided by the Nagykanizsa waste-water treatment plant. The project is expected to be completed in the spring of 2012, and will bring a significant improvement in the overall quality of life for the local population.
