Vastint builds a collector to Protect Poznan's Old Town from the effects of heavy rain and storms
In Poznan's Stara Rzeznia area, the stormwater collector is being reconstructed. The 360-meter section of the collector will collect, among other things, excess rainwater from the historic Old Town area. The investment is fully funded by Vastint Poland.
"The collector is a concrete pipe with a diameter of 1.6 meters, designed to effectively collect excess water from heavy rainfall, which is becoming more frequent in the era of climate change. In Poznań, such intense phenomena occur about ten times a year," says Ewa Łydkowska, spokesperson for Vastint Poland. "We are pleased to provide such a support to the city of Poznan as this investment will not serve directly the estate being developed in the revitalized Stara Rzeznia, but the entire community."
The collector being built by Vastint will have a total volume of over 720 m³, equivalent to the volume of a large swimming pool at "Chwialka." However, the collector will never be completely filled with water because its main purpose is to efficiently drain excess rainwater flowing from the streets of the Old Town during downpours and storms.
The collector is placed in a 7-meter-deep trench. Due to the exceptionally high groundwater level (the highest in Poland in 11 years), the construction is technically complex, and the collector itself is placed on piles. After completion, it will be covered with soil and the surface of a new street (the so-called New Boznicza), which will connect the existing streets: Boznicza and Polnocna. The construction of the new artery is another investment planned by Vastint as part of the revitalization of the Stara Rzeznia.
The investment is being carried out on behalf of Vastint by AARSLEFF, a company that has been operating in Poland for almost 30 years and specializes in the most difficult and specialized geotechnical, hydrotechnical works, and trenchless renovation of sewer and water networks. The completion of the investment, which began at the beginning of this year, is planned for the end of this year.
