Disruption in the purification process at Oostvoorne sewage treatment plant
The purification process at the sewage treatment plant (RWZI) in Oostvoorne has been disrupted. The likely cause is the discharge of a harmful substance, which has impaired the bacteria responsible for purifying the wastewater.
Investigations revealed that the harmful substance entered the system via the sewage pumping station on Europaweg in Rotterdam. To prevent further damage, the inflow of sewage from this pumping station (Maasvlakte 1, 2, and Europoort) was temporarily shut off on Tuesday afternoon, March 24, at 5:00 PM.
Research has shown that the discharge causing the issues originated in the Europoort area. As a result, the outflow from Europoort to the treatment plant remains closed, while the outflow from Maasvlakte has resumed.
The Municipality of Rotterdam has requested companies in Europoort to temporarily shut down their sewage pumps until the water authority indicates that it is safe to resume the outflow.
The Municipality of Rotterdam, DCMR, and our water authority are collaborating on an investigation to identify the source of the discharge.
The water authority is continuously monitoring the situation and working with multiple parties to resolve the disruption.
