Wellington Water Mechanical Failure Leads to Sewage Discharge

After a night of heavy rain, Wellington Water encountered a mechanical failure at its Moa Point treatment plant, resulting in the discharge of untreated sewage into the ocean. This situation was triggered at 3am on Wednesday, with wastewater being released through the short outfall into Tarakena Bay, potentially causing cloudy water. Additionally, treated sewage was discharged into Karori Stream and Waiwhetū Stream on Tuesday evening. Monitoring recommendations suggest avoiding the sea for two to three days post-heavy rain.
