We are working on a programme to improve the wastewater system that serves Porirua and the northern suburbs of Wellington city. With long-term investment in the network and upgrades to the treatment plant, the programme will help improve water quality in Te Awarua-o-Porirua, the harbour, local waterways around the catchment and future-proof the system for growth.

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

Ths programme 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.



This is a joint venture between Porirua City Council (PCC) and Wellington City Council (WCC). Wellington Water Ltd (WWL) is implementing the project on behalf of both project partners.
