Safe and Sustainable, Uppsala, Sweden
Safe and Sustainable
Uppsala is one of the oldest cities in Sweden. Today it is also one of the fastest-growing cities in the country. Over the next few years, completely new neighbourhoods with approximately 14,000 new homes will be built in southern areas of the city. Weholite ensures safe and reliable transportation of stormwater and waste water - and safety is of utmost importance because the newly installed pipelines will run through a water protection area.
Uppsala with its population of 170,000 is Sweden´s fourth-largest city, and today faces strong pressures to grow and develop. During the next few years, approximately 7,000 new homes will be built in Rosendal, a district located a few kilometres south of the city centre. In addition, plans to build approximately the same number of homes in Ulleraker, close to Rosendal, are being drafted. Since large parts of these districts do not have water supply or sewerage, the municipal water utility Uppsala Vatten och Avfall is building new main pipelines for both stormwater and waste water between the Rosendal, Kungsängen and Ulleraker districts.
Built to last for more than 100 years
The customer selected structured-wall Weholite for the pipes. Since the pipelines are being installed through a water protection area, it was essential that the pipe system has been proven to be thoroughly reliable and durable. Weholite is built to last for more than 100 years. Furthermore, it is efficient and fast to install thanks to its lightweight, long pipe lengths and prefabricated, customized and ready-to-install products. Uponor Infra has delivered 1,350 metres of Weholite pipes in dimensions of 500-1200 mm as well as 16 waste water manholes for the project.

Porin ja Harjavallan välille valmistui massiivinen jätevesien siirtoviemäri.
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.
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.
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.
