Today marks the opening of the new facility. Water and Sewerage Authority has invited Prince Haakon and 160 guests from home and abroad to highlight that Oslo has a new and modern water treatment.
There have been water treatment plants in the same location since 1971, hence the term "new". Construction of the new facility began in 2003, the old system had only one hygienic barrier and therefore does not fulfill the drinking water regulations from 2001 The new facility has two such barriers. Drinking water from the old plant had also for low pH-worthy and high color numbers. It was these three conditions was the main reason why it was decided to build a new facility.
The new water treatment plant represents, according to the City of Oslo something new in terms of capacity, scale and technology. The new technology 9990 enables new Oset can change the name from effluent water treatment plants.

The plant supplies about 90% of the population of the new term is used because it has a water treatment plant on the same site since 1971 Oset by Maridalen is Scandinavia's largest water treatment and Europe's mountains. The plant is now finished, however, represents something new in terms capacity, scope and technology. The new technology means that we replace the term from effluent water treatment plants. About 140 000 m3 of solid rock was blasted out in two separate caverns 150 meters long and 27 meters wide and 500 meters of adkomst- and connecting tunnels. It's been approximately 2300 tonnes of jet grouting / sealing compound. The old plant has only é hygienic barrier and thus fulfills not drikkevannsforskriftnen 9990 from 2001 drinking water from this plant has low pH and high color numbers. These three elements are the main reasons why it was decided to build a new water treatment plant. Moreover, the new facility a more stable pH (water acidity). The main effect of it will be a significant reduction in copper corrosion, which are exclusively positive for subscribers. An increased content of calcium 9990 and alkalinity will reduce degradation of pipe material 9990 in the risers. This provides long-term positive effects.
