Start-finish: Early 2023 – mid 2024
Location: Kaipatiki Road, Easton Park Parade and Kahika Point Reserve
Status: Construction
Project overview
The Kahika branch sewer rising main has been in service for more than 50 years. Since 2017, four significant failures of the existing branch sewer rising main have occurred and as a result it has been identified as a high priority for replacement as part of our asset renewal programme.
The Kahika wastewater upgrade project includes the following works:
-
Constructing a new two-kilometre-long wastewater pipe. It will be installed from the pump station in Kahika Point Reserve along Kaipatiki Road and up Easton Park Parade connecting to the existing Kahika branch wastewater line.
-
Diversion of four small local network catchments away from the existing Kahika branch wastewater pipe.
-
Decommissioning sections of the existing Kahika branch wastewater line.
Once complete, this project will contribute towards reducing wastewater overflows and discharges into the Kaipatiki Creek. It will also improve access to the rising main to support ongoing maintenance in the unlikely event of any future network failures.

Watch
Press play on the video to find out about the work involved to upgrade the wastewater network and how pipe pull trenchless technology is helping us keep community disruption to a minimum. Our team carried out a pipe pull from the Kahika wastewater pump station to Francis Kendall Reserve - that's 380 metres of pipe - and there was no need for extensive excavation.
