Consultation has concluded

Feedback on a preferred option for treating and disposing of wastewater from Hāwea has is now closed. Updates on the project can be found at https://www.qldc.govt.nz/your-council/major-projects/upper-clutha-wastewater-conveyance-scheme/.


Background

The existing Hāwea Wastewater Treatment Plant (WWTP) was built in 1988 and subsequently upgraded in 2000. Fast forward over 20 years and the Hāwea WWTP cannot satisfactorily meet current and growing demand. As a result we are consistently failing to meet discharge consent conditions.

We're planning an interim upgrade to the existing wastewater treatment plant to alleviate immediate operational issues. We've also now landed on a preferred long-term option that can respond to and futureproof Hāwea’s wastewater needs.


The preferred option

The preferred option is to pump wastewater to the Project Pure wastewater treatment plant for treatment and disposal. A new pipeline would be installed between Hāwea and Albert Town, where it would connect into Wānaka’s wastewater scheme. Upgrades to the infrastructure from Albert Town onwards would also be completed to cater for the increased volume.

This has been selected as the preferred option because it provides the best balance of environmental, social, cost and resilience benefits. Of the options considered, it is likely to be the fastest solution to implement, and can be constructed within the 'design life' of the interim solution.


preferred long term Hawea wastewater pipe alignment


We are currently developing the concept design of the preferred option to provide increased certainty of its feasibility and downstream network impacts.

The concept design phase will include assessment and design of the general pipe alignment, the Hāwea and Clutha River crossings, and upgrades required to Wānaka's wastewater network.

Your feedback on the preferred option is important. It will:

  • Allow the project team to tailor the the proposed options in line with the wants and needs of the community
  • Ensure elected members have a broad understanding of how the community feels when making a final decision to invest in this option.
