Open House at the Oosthuizen Wastewater Treatment Plant on April 18

On Saturday, April 18, we are hosting an open house at the wastewater treatment plant in Oosthuizen. From 10:00 a.m. to 3:00 p.m., visitors can see for themselves how wastewater is treated and how HHNK uses the new Nereda technology in this process. 

The open house offers local residents a unique opportunity to see how the water that flows into the sewer system every day is treated and returned to surface water in a clean state. HHNK staff will lead tours and explain how the treatment process works and what innovations have been implemented in recent years. 

Interactive activities 

Visitors can look forward to an informative and interactive programme. For example, they can: 

  • look through a microscope to see all the creatures living in the water;
  • experience how water treatment works using virtual reality (VR).
  • There will be a scavenger hunt for the children during the tour.
