We are working on a programme to improve the wastewater system that serves Porirua and the northern suburbs of Wellington city. This will help improve the health of Te Awarua-o-Porirua and local streams and beaches, through investment in the network and upgrades to the treatment plant. This work will also help future-proof the system as our population grows.
Ko Te Awarua-o-Porirua he taonga tuku iho a Ngāti Toa Rangātira
Te Awarua-o-Porirua is an ancestral treasure of Ngāti Toa Rangātira
This work supports the Porirua community's ambition and the Porirua City Council’s strategic priority to improve the health of the harbour, a unique and precious estuarine environment.

The wastewater network is a joint venture between Porirua City Council (PCC) and Wellington City Council (WCC). Wellington Water Ltd (WWL) manages the network on behalf of both partners.
In 2019 we undertook public consultation and worked closely with a collaborative group to help inform our plans for the wastewater network. The collaborative group included representatives from PCC, Ngāti Toa, Greater Wellington Regional Council, WCC, the Te Awarua-o-Porirua Whaitua Committee and other community groups and stakeholders.
