"Residents of Wellington have been advised not to enter the water, collect seafood or even walk their dogs on local beaches. On Wednesday, the lower floors of the Moa Point wastewater treatment plant were completely flooded after heavy rain caused sewage to back up into the 1.8km outfall pipe that normally discharges treated wastewater into Cook Strait, according to Wellington Water. As a result, untreated sewage began flowing through a shorter five-metre outfall pipe into the waters off Wellington's south coast."
"Wellington Water chief executive Pat Dougherty said around 70 million litres of raw wastewater had leaked into surrounding waters, New Zealand's 1News reported. Dougherty said he was at a loss to explain why the outfall pipe failed, adding: The outfall pipeline has more capacity than the treatment plant itself, it's designed to be the one thing that works whatever happens."
A sewage leak at Wellington's Moa Point wastewater treatment plant flooded lower floors after heavy rain and caused sewage to back up into the 1.8km outfall pipe. Untreated sewage flowed through a shorter five-metre outfall into coastal waters off Wellington's south coast. Around 70 million litres of raw wastewater leaked into surrounding waters. Residents were advised not to enter the water, collect seafood, or walk dogs on local beaches. Partial restoration allowed pumping about 900 litres per second through the long outfall and screening systems removed sanitary pads and wet wipes. Peak flows may require use of the short outfall and repairs are expected to take months.
