E64 Machine and process 3 – The transfer plant (Konghaugen reindeer treatment plant)

Summary

Ålesund municipality and Sula municipality cooperate through the project "BLÅ – fjords for the future", to construct a new sewage treatment plant at Kongshaugen (Kvasnes) in Sula municipality. The aims in the project are as follows: Cleaner fjord systemLovlig system for sewage waterBærekraftig system for the futureIt new sewage treatment facility shall be built in rock and have sufficient treatment capacity to handle sewage water that shall be supplied from Sula municipality and Ålesund municipality. The facility is dimensioned for 69,000 person equivalents and it shall be designed as a secondary treatment facility. The new treatment facility shall replace seven existing treatment plants and some interceptors for sludge. The sewage water must therefore be pumped from the existing treatment plant to Kongshaugen via a comprehensive transfer system. The transfer facility will have approx. 34 km sewage pipelines and will contain 25 objects, including approx. 28 km submarine pipelines, 6 km pipelines over land, 3 valve houses/manholes and nine pump stations. The contract work for the construction of the transfer facility will be organised as nine parallel execution contracts. For a more detailed description of the other contracts see Part A - General part.
