Storm water of the railway station, Konin, Poland
Modernization of the stormwater system of the railway station in Konin
The aim of modernising the 230-kilometre Sochaczew-Swarzędz railway line, which is estimated to cost PLN 463 million, is to speed up travel between Warsaw and Poznań. The project includes the construction of local control centres, modernising four stops and five stations, as well as replacing 160 km of tracks. However, in order for train traffic to run smoothly, an efficient storm water system is required to protect the tracks and other infrastructure from flooding. One of these projects was completed at Konin station.

Storm water for the railway station
As part of the modernization of the storm water system at the Konin railway station, Uponor Infra retention tanks were installed. They will store approx. 500 m3 of storm water. HDPE tanks with a diameter of DN3000 and lengths 61.39 and 16.39m optimally use the area between the tracks. Uponor Infra specializes in supplying infrastructure solutions tailored to customer needs.

Full tightness and optimal use of available space
There were several reasons for this decision. One of the main ones is the fact that thanks to extrusion welding, PE-HD systems are 100% tight and homogeneous, also at the point of connection. In addition, the modular design makes optimal use of the available land (the tanks were placed between the tracks, at the site of the decommissioned platform, in narrow trenches with formwork).
PE-HD components were delivered to the site in mid-January 2020 and extrusion welding services were completed in early March. Both tanks were placed in trenches using a crane at a depth of 4.5 m. The tanks were placed on a 30 cm bedding and additionally, for protection, in case of an increased level of groundwater, they were anchored to the footing.
Weholite PE-HD DN3000 pipes were used to build the tanks and two pumping stations were designed behind the outlets, with the capacity of Q=10 l/s each. In addition to the permanent connection of the tank body by means of extrusion welding, the double-wall construction provides double security and guarantees leak tightness. Tanks are made of pipes with stiffness class SN8 kN/m2, according to PN-EN ISO 9969.
The works at the Konin station related to the water and sewage infrastructure also include the reconstruction of the water pipeline, construction of the sanitary sewage system, connections and a drainage ditch. After the completion of the modernisation of the Sochaczew-Swarzędz line, passenger trains travelling on this line will reach speeds of 160 km/h, and 120 km/h for other trains.
