Resource Consents


Wastewater Conditions

The consents that the City's current Wastewater System operates under were granted in October 2005 and April 2006. The system was originally chosen in 1990 following five years of intensive work by the Council with key stakeholders, tangata whenua and the wider community. The system was selected on the basis that it would serve the people of Tauranga for the next 30+ years.

The Wastewater System that is in place today, with some additional enhancements, reflects the following recommendations that were adopted by the Council in 1990:

  • The original discharge outfall into the Otumoetai Channel has been sealed and no longer discharges to the Tauranga Harbour 
     
  • The total treated wastewater flow is passed through wetlands at Te Maunga before being discharged via the ocean outfall 900m off shore. 
     
  • All ocean outfall discharges are able to be UV treated should this be required in circumstances where discharge water quality may potentially breach consent limits. 
     
  • Tangata whenua and the public were involved in the design and construction of the Wetlands at Te Maunga 
     
  • The current Wastewater System is flexible enough to adapt to changes in technology as they become available 
     
  • The Mount Maunganui Harbour Reclamation Act has been repelled so no further expansion of the old Te Maunga oxidation ponds can occur. 
     
  • The layout of the wetlands, ponds and treatment facilities have been developed to provide a natural environment.

Wastewater Monitoring

The resource consents include a comprehensive set of conditions that require the Council to regularly monitor the discharges from the Wastewater Treatment plants for any effects on the environment.

What monitoring is required for the discharge of treated wastewater to the ocean?

A very extensive monitoring programme is required for the discharge of treated wastewater to the Pacific Ocean. This includes:

  • monitoring the amount and flow rates of the treated wastewater discharge 
     
  • monitoring the treated wastewater quality. This includes 20 different types of tests 
     
  • testing the Pacific Ocean receiving waters at 9 locations for microbiological levels 
     
  • testing shellfish for microbiological and trace metal levels  
     
  • every 10 years the Council must undertake a comprehensive ecological survey of marine life and sediments in the vicinity of the outfall.

What monitoring is required for the air discharges?

The air discharge consents from the Chapel Street Wastewater Treatment Plant and the Te Maunga Wastewater Treatment Plant include monitoring conditions that require the Council to:

  • maintain an odour complaints register 
     
  • periodically undertake odour measurements at specified locations 
     
  • walk around both treatment plants once a month to inspect for any odours 
     
  • biennial odour survey of the communities around both the Chapel Steet and Te Maunga treatment plants
