About the Nereda® WWTP Stein

The challenge

In order to 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 their technology of choice in accordance with their own Verdygo® concept.

Since their wwtp at Panheel is about the same size as Stein it was decided to design and build the new plants at the same time. For both plants an identical 40.000 p.e. Verdygo Module has been developed in cooperation with Mobilis, Engie and Eliquo.

The solution

The 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 was selected as the technology of choice for Verdygo. After successful implementation at Simpelveld in 2015 and Weert in 2019, these will be the third and fourth Nereda in Limburg.

Because of the small footprint of Nereda, the client has been able to build the new plant next to the existing plant on the existing plot of land. Once the Nereda plant is operational in 2021, the existing plant will be decommissioned and amovated.

The outcome

The WWTP in Stein will treat the wastewater of 33,500 people and live up to the new strict effluent requirements.
