Oygarden STP – Norway’s Latest STP Buried in a Mountain
April 21, 2021
Norway’s west coast comprises of more than 300 islands that lie within the municipality of Fjell. With the nearby city of Bergen now more accessible via new transport infrastructure, the Fjell region has been experiencing rapid population growth.
To comply with recently changed environmental regulations a new wastewater treatment plant was required and given the landscape in this part of the world, the construction of the new Oygarden STP required a design that utilised as little space as possible.

The second stage will see the construction of a new secondary treatment facility.
