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

Application Documents

The application, including an assessment of environmental effects and all supporting information, can be viewed on this page. Alternatively, hard copies can be viewed at Greater Wellington Regional Council, 100 Cuba Street, Te Aro, Wellington during normal office hours.
