Massiivinen jätevesiviemäri Harjavallasta Poriin
Porin ja Harjavallan välille valmistui massiivinen jätevesien siirtoviemäri.
Construction of storm water collectors at Przemkowska street in Nowe Polkowice is one of the stages of a big investment concerning the drainage of the district. Uponor Infra (former KWH Pipe) was a supplier of pipe systems PEHD Weholite SN8 within the diameter range dn 500÷1600mm. The storm water separation system was constructed in collaboration with NavoTech Inżynieria Środowiska. In the course of execution of the project the heavy and complex structures of concrete separators were replaced with the modern system of separation and pre-treatment of storm water in Weholite technology of diameter dn 3000mm.
Uponor Infra produced and delivered also the Weho manholes, which supplement the pipe systems. The application of unique technology of Weholite pipes and connection of elements of the manholes and pipes with the use of extrusion welding ensures their high quality and 100% tightness. Thanks to small weight the Weho manholes are easy to transport, unload and install. The manholes are delivered to the construction site as monolith structures with factory made connections, which allows to save the assembly time at the construction site and thus reduces the construction costs and ensures exceptional durability of their operation.
Despite very difficult winter conditions the works were carried out efficiently. The system was started up and released for operation in February 2013.

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.
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.
