THIS OPPORTUNITY IN A NUTSHELL - Significant rainfall events in the Kaikorai Valley catchment exceeds current wastewater network capacity and leads to wastewater flooding, contamination and health and safety risks to residents in South Dunedin.
The permanent engineered solution will take significant time and therefore we have an urgent immediate need for an interim solution.
Wastewater from the Kaikorai Valley catchment flows to the Tahuna Wastewater Treatment Plant (WWTP) via a piped network that passes through the Caversham Tunnel and South Dunedin.
The DCC has allocated funding in its 2018-28 Long Term Plan for a new pipeline to divert Kaikorai Valley wastewater flows to the Green Island WWTP and for the Green Island WWTP to be upgraded with the capacity to treat these flows.
Commencement of the pipeline and WWTP upgrade is expected to be 3 – 4 years away due to the time required to gather data, design and consent the work. Construction is expected to take approximately 3 – 4 years to complete. The South Dunedin community has made it clear that having to wait this long to resolve the wastewater flooding issue is not acceptable.
As an interim solution; to alleviate the frequency and severity of wastewater flooding in South Dunedin; the DCC is seeking to establish a temporary wastewater overflow to the Kaikorai Stream.
The intention is for the overflow to be able to be operated in significant rainfall events to discharge up to the full flow of wastewater from the Kaikorai Valley catchment into the Kaikorai Stream with coarse/primary screening.
The outfall structure is intended to have a service life of no more than 10 years, a sufficient timeframe for the new pipeline to and upgrade of the Green Island WWTP to be completed.

The DCC is seeking to partner with a professional services provider who will work alongside the DCC to manage all aspects of the investigation, feasibility and design.
It is essential that the professional services partner has exceptional stakeholder engagement and management skills as the consenting and agreement aspects are likely to be challenging. The DCC is happy to share risk in this project where it will accelerate the project programme.
The professional services partner will then prepare the construction tender, act as engineer to the contract and monitor construction.
