Investigative Report Reveals Operational Failures at Moa Point Sewage Plant
What happened
A newly released report details the catastrophic failure of the Moa Point sewage treatment plant, which was caused by a combination of technical and organizational factors. The plant experienced flooding five times in the months leading up to the disaster. The failure occurred while the plant was undergoing critical upgrades to its ultra-violet disinfection channels, which temporarily reduced its capacity to treat sewage.
