Shutdown of the main outfall pipeline to Pencarrow (up to 6 weeks)
A shutdown of the main outfall pipeline that carries fully treated wastewater from the Seaview Wastewater Treatment Plant to Pencarrow will be in place for up to six weeks from Monday 25 May 2026. The shutdown is for a planned programme of maintenance on the pipe, pump stations, and related machinery and installations, to support resilience and operation of the pipeline. The maintenance is being conducted in accordance with our resource consent with the Greater Wellington Regional Council. For the shutdown and works to occur, the pipeline needs to be emptied. This will involve discharging fully treated wastewater from the main outfall pipe from scour valves along the coast
