Sewage and drains

Wastewater and sewage water are most often passed through pipes and sewages under the ground. These pipes are often extended far beyond built up areas. The wastewater consists of liquid waste from different houses and blocks around a city or a village. And sewers consist of feces, urine and sometimes waste (like plastic and etcetera). Usually all municipalities have different municipal drains where pipes lead the wastewater to sewage treatment plants around the city. Then, after the treatment the wastewater is clean and released into the ocean as perfectly clean water.

Wastewater treatment plans and where they are located

Nesodden has three municipal treatment plants, these three treatment plants take care of, and are located at Tangen, Fagerstrand and Kirkevika. The treatment plant at kirkevika does not fulfil today’s requirements on how a treatment plants should be and work, which is why VEAS plans to launch or substitute a new treatment plant nearby. The treatment plans for Fjellstrand, Bjørnemyr and Alværn are not located on Nesodden. The treatment plans for Fjellstrand, Bjørnemyr and Alværn are in Asker. The sewage water from these three areas is led to Asker through underwater pipes in Oslofjorden.

 If municipal crisis where to happen

The local drinking-water in Nesodden is safe to drink and it has a very good hygienic quality. Eurofins (accredited laboratory) executes all kinds of analyses on our water tests. If any mistake is discovered on the tests they take, the community will be reminded immediately from the laboratories. When it has been forwarded to the community, the leaders here in Nesodden will message all the inhabitants (via SMS on mobiles) that there is something wrong with the drinking water. If this case is critical, the community will send out a few advices which are wise to follow. If anyone would like more information during one of these situations, updated info will be posted on the community’s website. So, if a leak happens in the drinking-water or the sewer the inhabitants and the town’s population will be updated regarding what has happened very quickly. If a leak were to happen, VEAS would also send out people to inspect and examine some reasons behind the leak.
