Area of natural beauty to gain from new wastewater facilities

A protected natural area in central Poland is to acquire a much-needed collective sewer system. Covering five municipalities in and around Zielonka Forest Landscape Park, this new infrastructure will benefit thousands of permanent and seasonal residents.

A range of state-of-the-art sewage facilities is being built under the project. Two old wastewater treatment plants will also be decommissioned.

Protected nature and recreation spot

Located north-east of the city of Poznan, the Zielonka Forest Landscape Park was set up in 1993. It covers some 12 000 hectares and includes five nature reserves, several lakes and primeval forest tree species such as pine and larch. The beauty spot is also popular with walkers and cyclists.

The project aims to build a collective sewer system in the Murowana Goślina, Czerwonak, Swarzędz, Pobiedziska and Skoki municipalities, in line with Poland’s National Programme of Urban Wastewater Treatment. These five municipalities belong to the Puszcza Zielonka Inter-Communal Association, which is also responsible for promoting the Zielonka Forest Landscape Park. At present, the 107 000 inhabitants in the target area lack a systematic or legally compliant solution for sewage management.

Construction and installation contracts will also cover the connections to the sewage network and reconstruction of the surface. The Pobiedziska and Skoki Wastewater Treatment Plants will be decommissioned, while new pumping stations will be built to deliver the sewage from their catchments to the existing sewer network. There are also plans to purchase around 15 ha of land, for the sewage pumping facilities and pipelines envisaged in the project.

Collective sewage infrastructure

The collective sewer system will feature new gravitational sewers and compressor discharge pipes, plus intermediate wastewater-pumping stations that include two drainage catchments on the territory of the five target municipalities. The entire system will be connected to existing wastewater treatment plants in Koziegłowy and Szlachecin.

Thanks to the project, some 42 300 inhabitants will be connected to the sewage network. This will increase the connection rate from 55% in 2007 to 83% in 2015 in the Murowana Goślina agglomeration and to 84% to 85% in the Poznań agglomeration.
