Seaview Wastewater Treatment Plant outfall pipe repair
Fully treated wastewater is currently being diverted into the Waiwhetu Stream as a result of a joint failure in the
Seaview Wastewater Treatment Plant outfall pipe early this morning.
Our contactors are working as quickly as possible to repair the joint failure. It will take most of the day to drain the
outfall pipe and repairs will begin as soon as the pipe is drained. We expect that the repair will be completed within
two days.
To assist in draining the outfall pipe, scour valves (additional drainage points) have been opened between Windy Point
and Burdens Gate in Eastbourne. Health warning signs have been erected advising people not to swim or collect seafood in
the affected areas and water quality testing is underway.
The discharge via an overflow pipe into the Waiwhetu Stream is a consented contingency in case of emergencies.
More information
· The Seaview Wastewater Treatment Plant treats all wastewater from Upper Hutt and Lower Hutt
· The plant treats around 50,000 m3 of wastewater a day
· All wastewater discharged from the plant is fully treated
· The outfall pipe runs from the Seaview Wastewater Treatment Plant to the Pencarrow Head outfall
· When the outfall pipe is unavailable, due to maintenance or repairs, fully treated wastewater is diverted to the lower
Waiwhetu Stream
