Sewage pipelines to sewage treatment plant - HDD method, Szczecin, Poland
Building of forced sewage pipelines to sewage treatment plant - HDD method
In 2007 in Szczecin, a series of record-breaking in the European scale number of crossings of a high dimension PEHD pipeline under a water obstacle made with a horizontal drilling method was completed in Szczecin. The engineering work was done within the "Improving water quality in Szczecin" programme.
The contractor scheduled using 3 different pipeline founding technologies: open excavation, microtunneling and horizontal drilling, where 6 largest crossings under water obstacles with the total length of over 3 km was done without excavation. The open excavation and microtunneling technology used standard PEHD WehoPipe pipes with DN 1000 x 59.3 mm PN 10 SDR 17. In the tunnels made by horizontal drilling, due to very hard geological conditions and founding at the depth of ca. 20 m, pipes with thicker outer walls were applied (dzxe 1033.2 x 75.9 SDR 13.6 MOP 12.5). The pipes were produced and delivered to the site in 15-metre sections to minimise the number of welds on the pipeline course.
In December 2006 after making pilot drilling, the first actual drill was made at the Customs Office. 460 and 465 m long sections were pulled into the drill under the Oder. The pipeline sections under the Parnicki Canal - 360 and 570 m long were founded in February 2007. With regard to a lack of space to mount the pipeline near the crossing, they had been welded on the Pucka Island, launched and transported by tugs to the site. In the case of the shorter section the whole pipe was pulled out of water and placed on rollers. The longer section was almost entirely pulled directly from the canal. It is worth noticing that it was the first in Poland installation of such a large polyethylene pipe transported and mounted almost completely from water. The pipelines were founded at the level of Pucka Island between March and April 2007. 620 m and 626 m long pipes were installed, breaking a new European record in the length of a large-dimension pipeline pulled into an HDD drill.

Det nye laste- og parkeringsområde på Volvos centrallager i Vantaa skulle asfalteres, hvilket krævede en pålidelig løsning til effektivt at kanalisere regnvand væk fra området. Uponors nye IQ-infiltrationsrør blev valgt som løsningen til at infiltrere og tilbageholde regnvand på grunden.

To rebuild an office building located in the heart of Amsterdam into 150 appartments in a relatively short time is definitely a big challenge.
Rapid action was critical when a sewage collector broke in Warsaw, Poland, causing a massive waste spill into the Vistula River. Uponor Infra’s crew worked 24 hours a day in order to stop the pollution of the river. A temporary pipeline was produced, delivered and connected in just eight days.
Thanks to swagelining technology, it was possible to carry out most of the water line modernisation works in the centre of the city of Łódź, in a built-up area, along traffic lanes with heavy traffic of motor vehicles and trams.
Construction of storm water collectors in Nowe Polkowice is one of the stages of a big investment concerning the drainage of the district.
A sea outlet of treated wastewater was initiated in Swarzewo. It is yet another of the many environmentally friendly projects that have recently been carried out in Poland where PE pipes were used.
City of Lahti is building new neighborhood called Ranta-Kartano. While they were constructing basic infrastucture the city saw the possibilty to reserve some ground space for storm water management. Now there is a test running for different kind of storm water management. Uponor is involved with new type of storm water filter.
September 2018 saw the launch of the project for a stormwater drainage system in Rzeszów, almost 26 kilometres long, in the residential District of Budziwój, which partially coincides with the floodplain of the River Wisłok. One of the elements of this system is the retention canal. The project, scheduled for delivery by May 2020, will help to finally solve flooding problems which have been plaguing the residents of this region of Poland.
