After a lot of preparation work inside the Henriksdal treatment plant, work on expanding and upgrading the treatment plant has now embarked upon a new stage where more work has to be done and more noise is generated. There is now more impact on residents and people working at Henriksdalsringen, and this work is estimated to continue for about 2 years.
Ongoing work at the treatment plant
Where: Inside the treatment plant, we have shut down two storage ponds that are currently being refurbished in order to install the new membrane technology.
Our working hours are 7am to 10pm on weekdays.
The technology tunnel
Where: Inside the Henriksdalsberget mountain, above the treatment plant and beneath the properties at Henriksdalsringen. We are building the technology tunnel needed to provide the new membrane ponds with the technology required. People living on the mountain can hear how we are blasting, and the residents have begun to detect drilling work as well. You can find out more about this work here.
Sludge dewatering building
Where: We are also working on the Stockholm Vatten och Avfall site to build a new plant for handling the sludge produced by the treatment plant. This involves us blasting out rock in order to make space for the plant, and a new building will be constructed on the mountain as well. Sludge is currently handled outdoors at the Sickla plant. When the expansion of the Henriksdal plant is complete, all sludge will be handled inside the mountain and thereby eliminate the spread of unwelcome odours in the local area.
