Investigations for the project were completed in January 2024.

Wellington Water and Porirua City Council are now working together to secure funding for the pipeline construction. This will be worked through as part of the Council’s long-term planning process.



Why are we doing this?

This project is part of a wider programme of work we are undertaking on behalf of Porirua City Council to upgrade the city's wastewater network, increasing its capacity and resilience for residential growth and protecting public health and that of Te Awarua-o-Porirua Harbour and local waterways.


What's involved?

The work involves installing a new pipe down the centre median of SH59 and partly adjacent to the rail corridor at the southern end of the works, and installing a connection into the new Porirua Central Wastewater Storage tank currently under construction. 

The project is currently in the investigations phase involving drilling bores and test pits along  pits along Papakowhai Road, Paremata Crescent and the centre median of SH59 to locate existing services.
