Message from Wellington Water 01 April 2022:

Wellington Water is preparing for formal hearings as part of the Porirua Wastewater Treatment Plant consent application process. The consent application process had been paused while independent reviewers investigated the sludge management process at the Porirua Wastewater Treatment Plant, and the regional wastewater treatment plant operating model. In brief, these investigations identified a number of areas for action and Wellington Water is continuing to implement improvements as a result. Further information is available here (https://haveyoursay.gw.govt.nz/69251/widgets/339300/documents/230146) and the operating model report is available here (https://www.wellingtonwater.co.nz/assets/DMSDocuments/Regional-Wastewater-Treatment-Plant-Review-Report.pdf). On balance Wellington Water is satisfied that the key issues are now in hand and do not affect the consent application as lodged. The timeframe for the application had been extended in accordance with s37 of the Resource Management Act. The next step is the formal hearing of the consent application by an independent panel. This is currently scheduled for June 2022.


Update 12 Nov 2021

Recent issues with sludge have highlighted to Porirua City Council (PCC) and Wellington Water Limited (WWL) that they need to take a further look into the Porirua Wastewater Treatment Plant operation and performance. An independent review of the issues is taking place. During this time the resource consent process will be paused* as there may be improvements from the review that may impact the consent application. In the meantime, WWL will also complete an updated maintenance and operations plan for improving operational performance. WWL has also committed to engage with the community in a transparent way in relation to the findings of the review, and will consult further should the review result in a change in the consent approach. At this stage, PCC expects to be able to proceed to a hearing before June 2022. Any further updates to the process including notice of the hearing will be published on this page. 

* The timeframe to hold a hearing has been extended in accordance with s37 of the Resource Management Act.


Summary of the proposal

Wellington Water Limited (on behalf of Porirua City Council (PCC)) has applied to Greater Wellington for resource consent for discharges related to the continued operation of the Porirua Wastewater Treatment Plant (the treatment plant). The treatment plant takes wastewater from the residential and commercial areas of Porirua, and the northern suburbs of Wellington. Consent is required for:

  • Discharge permit for the discharge of a contaminant (odour) to air from the treatment plant
  • Discharge permit for the discharge of treated and partially-treated wastewater to the coastal marine area off Rukutane Point from the operation of the treatment plant.

Odour is generated as the untreated wastewater enters the treatment plant, and within the milliscreen building at the treatment plant. The air discharge consent application proposes to continue current management practices that minimise odour.

The discharges from the treatment plant to the sea relate to the discharge of fully treated and disinfected (by ultraviolet light) wastewater, as well as intermittent discharges of partially treated wastewater until capacity upgrades are completed in June 2023. These intermittent discharges occur when heavy rain significantly increases the volume of wastewater in the system, beyond the capacity of the treatment plant.

Consents Applied for:

  • Discharge permit [36727]: To discharge contaminants to air (odour) from the operation of the Porirua Wastewater Treatment Plant
  • Discharge permit [36816]: To discharge treated and partially-treated wastewater to the coastal marine area from the operation of the Porirua Wastewater Treatment Plant
