Uponor Vault cleans the storm water, Norrköping, Sweden
Keeping the Baltic Sea clean
Uponor Vault no. 2 = 3000 x 6000 mm
Tailormade solutions on site
A three-step process
The Uponor Vault effectively collects sediment and particlebound contaminants carried by stormwater run-offs. The first purification step consists of a coarse grid where coarser particles such as leaves and branches are captured. After the coarse grid, there is a sediment pocket that collects sediment from the stormwater. The final step consists of 12 tailor-made pipe filters – the number of filters is set based on the maximum flow the vault should have – with Filtrate P (Filtralite). The water is forced through the filters before it flows out of the vault and into the recipient. The goal is that before ending up in the Ljura Stream, the water is so clean that it does not exceed the EIA environmental quality standard. “The most harmful kind of stormwater is the so-called ‘first flush’ from the top layer of the asphalt that comes with heavy rain. Among other things, it contains heavy metals and salts
that flow directly into our stormwater chambers and then into rivers and streams. We want this first flush to get stuck in the filters,” explains Helena Aspdahl, Project Manager at Nodra AB. “This is a pilot project to investigate the purification effect of the vault by taking samples of stormwater before and after the treatment. When we know more, we can decide if maybe a different type of filter or an adjustment of some kind is needed. Also, we have to consider how to most effectively maintain the vault,” says Helena Aspdahl.

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.

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.
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.
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.
