ILF Consulting Engineers Polska (ILF Poland) is elaborating comprehensive design documentation for the final stage of construction of the Vistula collector – from the connection chamber with the Bielański collector to the “Farysa” facility, together with a pumping station and the necessary̨ accompanying infrastructure (stage III). This will be the largest transit and retention collector in Poland’s capital, which in addition is expected to prevent the negative effects of climate change. Budimex S.A. is the general contractor for the investment of the Municipal Water and Sewerage Company of the capital city of Warsaw. 

Besides transporting wastewater, the new infrastructure will also temporarily store the rainwater excess, decreasing the risk of flooding and reducing the launch of so-called storm overflows into the Vistula river. The investment has received approvals from the Documentation Coordination Group.

The existing storm sewers: Mostowa, Koscielna, Wenedów, Krasińskiego, Bielański, as well as the delivery sewer collectors to the “Farysa” facility and the pressure pipe from the “Powiśle” pumping station will be connected to the new collector.

The retention volume of the collector will be about 50,000 m³ with base diameters – for the entire stage – from 1.2 to 3.2 m. The entire collector will be almost 9.5 km long and will be founded at a depth of 6 to 15 m, along Wybrzeże Kosciuszkowskie, Wybrzeże Gdanskie and Wybrzeże Gdyńskie streets. The collector will be constructed using trenchless microtunneling technology.

ILF Poland’s task for this investment is to prepare comprehensive design documentation for the III stage of construction of the Vistula collector – specifically, from the connection chamber with the Bielański collector to the “Farysa” facility, along with the pumping station and the necessary̨ accompanying infrastructure,” explains Marcin Przepiórka, Managing Director from ILF Poland. 

The construction of collectors of this size will help reduce the risk of overflows and flooding, as well as the launch of so-called storm overflows during heavy rains, adds Marek Smółka, a Warsaw Municipal Water and Sewerage Company spokesman.

The investment is part of a broader project co-financed by EU funds and implemented by Municipal Water and Sewerage Company in Warsaw, which aims to prevent the negative effects of climate change by increasing retention in the sewage system.

ILF Poland began work in January 2022. Completion of the project documentation (construction design and detailed designs) is planned by the end of 2022.
