The challengeTo comply with the much more stringent regulations for effluent water quality (KRW) in 2021, the old WWTP at Stein from 1984 had to be replaced. The Water Authority of Limburg (WBL) selected Nereda as its technology of choice, per its Verdygo® concept.
Since its WWTP at Panheel was about the same size as Stein, it was decided to design and build two new plants at the same time. For both plants an identical 40.000 p.e. Verdygo Module was developed in cooperation with Mobilis, Engie and Eliquo.
The solutionThe Verdygo concept is a sustainable approach with a modular construction technique. By using modules built above ground, components can be added or removed, making it a flexible construction for future changes.
Nereda technology was selected as the technology of choice for Verdygo. After successful implementation at Simpelveld in 2015 and Weert in 2019, Panheel and Stein are the third and fourth Nereda plants in Limburg.
Because of the small footprint of Nereda technology, the client has been able to build the new plant next to the existing plant, on the existing plot of land.
