Petone Community Board Feedback


Consultation on Seaview Outfall Temporary Discharges




The Petone Community Board appreciates the opportunity to provide feedback on the shortlist of options that we understand have been put forward by Hutt City Council, Wellington Water and their consultants MWH.


We have looked at the alterative solutions to the current method for the temporary discharge of treated wastewater from the Seaview Wastewater Treatment Plant and wish to acknowledge the work that has obviously been done on developing a series of different possible solutions or improvements.



v Options 1, 2, 8 and 12 would retain an effluent discharge into or close to the mouth of the Waiwhetu Stream and likely all still allow effluent or effluent plume or nitrogen from effluent to affect the Waiwhetu Stream so we do not support these.


v Options 3, 5 and 6 each require the construction of a new pipeline to varying lengths and any of these could apparently be seen as the first stage of a duplicate pipeline to replace the current outfall pipeline to Pencarrow Heads.


v Overall we want to see less of an impact on the Waiwhetu Stream in the future and therefore definitely prefer options 3, 5 and 6 and support option 6.



We support option 6 because:

Option 3 could still have some limited plume effect on the Waiwhetu Stream

Option 5 could have an effect on the marina and beach area

Option 6 has better dilution than option 5 and seems less likely to have effects on the marina and beach areas


We would appreciate being a part of any consultation group so that we can have the best possible understanding of the issues involved in the future.
