Porin ja Harjavallan välille valmistui massiivinen jätevesien siirtoviemäri.
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.

Kuokkalaan avattiin marraskuussa 2013 kehäväylä. Väylälle asennettiin 2 kilometriä Uponorin IQ-hulevesiputkea, 250 kaivoa ja 5 kilometriä salaojaputkea.
Lahti Energia käyttää työmaillaan ensimmäisenä Suomessa kaariputkia. Kokemukset ovat olleet erittäin hyviä.
Lahden Vipusenkadulla uusittiin kaukolämpöverkkoa. Kaivantoon on laskettu isoja kahdentoista ja kuudentoista metrin DN 300 -putkia. Hitsaajat ovat ryhtymässä töihin. Jokin jää kuitenkin askarruttamaan ohikulkijan mieltä.
Samaan aikaan toisaalla, keskustasta Launeelle johtavalla kaukolämpölinjalla operoidaan hieman tuhdimpien DN 400 -putkien kanssa. Täälläkin sama juttu. Aivan kuin kaikki putket eivät olisi ihan suoria?
Butt welding by night of 900 mm pipes ensures stable operation of a district cooling solution in Copenhagen Harbour.
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.
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.
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.
