The Nya Rya Project will guarantee sustainable wastewater treatment in the Gothenburg region
Increased population, higher water flows and demands for stricter effluent limits are some of the challenges that Gryaab handles in the Nya Rya project.
Major expansion of the existing WWTP
The existing Rya WWTP in Gothenburg, Sweden, with 800 000 connected inhabitants (2021), is about to expand to a much larger WWTP with 1.35 million connected inhabitants in 2055. This is equivalent to an increase of the average influent flow from 4.5 cubic meter per second to 6.5 cubic meter per second. In addition to new water treatment processes this project also includes a new huge pumping station and considering a new tunnel for effluent wastewater. The project, called Nya Rya, started in 2021 and will be finalized in 2036.
