Next Steps for Central Otago Wastewater Projects
The next stage of investigations and planning for improved disposal of wastewater treatment for Alexandra, Clyde and Omakau have been given the green light by the Central Otago District Council (CODC).
At the meeting at Alexandra today (Wednesday 29 November 2023), the Council was provided with recommendations for moving forward with two new infrastructure projects designed to provide safe, reliable, and resilient wastewater services.
Since 2021, the CODC has been investigating options to improve the treatment and disposal of wastewater services and deliver better long-term environmental outcomes.
Two Indicative Business Cases were presented today for the proposed Omakau wastewater and Alexandra wastewater projects, to seek funding in order to progress to the next stage of investigation and preliminary design. This was a critical step to gather accurate information which would significantly inform and improve investment and construction decision-making for each project, CODC Capital Projects Programme Manager Patrick Keenan said.
“These projects would represent a significant investment for Council and accurate planning is crucial to ensure ratepayers' money is well spent on creating durable, resilient wastewater infrastructure. Our aim is to meet our growing communities’ needs today, whilst future-proofing for future generations and honouring our environmental commitments."
Once the investigation and preliminary design are undertaken, Council will be provided with updated business cases with refined costs and a delivery strategy for approval. Funding for the investigation and preliminary design work will be included in the Draft 2024 Long Term Plan (LTP).
The Omakau Wastewater Indicative Business Case recommends constructing a new wastewater treatment site at Omakau in a more resilient location, near the Omakau Golf Course. This includes moving the discharge of the treated wastewater away from the Manuherekia River to discharge to land.
The Alexandra Wastewater Indicative Business Case recommends constructing a new wastewater treatment site on Council land near the Alexandra Airport. This includes moving the discharge of the treated wastewater away from the Clutha Mata-au River to discharge to land. Council requested further investigation also be undertaken to determine if the existing Alexandra treatment site at Graveyard Gully has the capability to be expanded to meet long term requirements.
During discussion about why the current Omakau and Alexandra wastewater treatment sites were not viable for the long term, Three Waters and Waste Portfolio Lead Cr Nigel McKinlay commented that now was the time to cater for future growth by providing better capacity and quality of treatment and increased reliability. After the meeting he reiterated his comments, adding that:
“These are big capital projects. We will be aiming to have a complete set of target dates within the Draft 2024 Long-term Plan.”
The local communities and stakeholders will have the opportunity to provide input as planning for these projects progresses.
