No chemicals are needed to keep the water quality high in a medium-sized city in Finland where the water intake plant was renovated and the Uponor aeration tank was installed.
HSY (Helsinki Region Environmental Services HSY) is testing a new kind of area renovation operating model in Itäranta, Espoo, where the aim is to get the area's water supply network in order once and for all. New steps are also being taken towards more sustainable construction: the selected Uponor Blue pipes utilising renewable raw materials will reduce the carbon footprint of pipeline installations by 70% compared to traditional plastic pipes.
I de senere år er kvalitetsstyring af regnvand blevet en stadig vigtigere del af byernes regnvandsstrategier. Et pilotprojekt blev lanceret i Heinola for at rense regnvand med innovative filterbrønde udviklet af Uponor. Samtidig vil der blive indsamlet værdifulde forskningsdata om regnvandskvaliteten fra to forskellige typer områder og om de rensningsresultater, der opnås med filterbrønde.
Uponor’s Weholite technology was the key solution in a unique project in London, where the Lee Tunnel and Thames Tideway tunnel have the task of capturing an average of 39 million tonnes of sewage a year from the 35 most polluting combined sewer overflows (CSOs). An upgraded pipeline system was designed to reduce the number of overflows – and their environmental impact – from the sewers and treatment systems serving London. A particular aim is to limit pollution from the sewers and treatment systems connected to the Beckton and Crossness sewage treatment works.
The largest building project during 2017
The City of Espoo is the first in Finland to introduce the Vortex stormwater separation chamber. It can be used to efficiently separate floating and descending solids from stormwater. The aim is to reduce the maintenance costs of the retention system built from stormwater tunnels and prevent solids from ending up in waterbodies.
Modernizacja oczyszczalni ścieków to kluczowe zadanie projektu pt. "Kompleksowa modernizacja oczyszczalni ścieków w Opolu wraz z poprawą gospodarki wodno-ściekowej".
A biological chemical treatment plant became the solution
Construction of the pipe network for cooling water at the Keljonlahti power plant began in December 2008. 3,000/3,300 mm Weholite pipes were selected for the network. The combined length of the entire intake and discharge pipe network for cooling water is 1,714 metres.
