Christie Avenue Wastewater Pump Station
Over the next decade, we're making major investments into core infrastructure like wastewater. This has been strongly signalled in recent 10-Year Plans. A budget of $2.0 million
To improve the district’s infrastructure, we're upgrading the Christie Avenue Wastewater Pump Station. This facility pumps wastewater from households in the second largest catchment in Te Awamutu through to the Te Awamutu Water Treatment Plant for processing.
Works undertaken on the Christie Ave Wastewater Pump Station are due to commence on 5 October 2020, with a transformer being installed by Waipā Networks in December for the upcoming works.
The upgrade works include modifications to the existing pump station building including:
- Existing pumps replacement including two new wet submersible pumps.
- New internal pumping pipe works
- New electrical upgrade
- Structural floor support including new cover plates
- Crawl beam installation within the existing pump station
- Access door modification
- Odour control measures
- Roof replacement
- Exterior painting.
We will also installing new emergency storage tanks with an estimated storage volume of 270m3, new wastewater pipe lines and manholes within the designated boundary. To allow the installation of the new storage tanks will require bulk earthworks of approximately 500m3.
A new wastewater rising main with an external diameter of 315mm (approx. 500m in length), along the Christie Avenue - Mutu Street road corridor to connect to the existing wastewater rising main in Mangapiko Street is also in the schedule of works.
Upon completion of the pump station upgrade, contractors will reseal the right-of-way access for residents.

The reinforced concrete walls for the wastewater storage tanks have now been poured and contractors have started testing the tank. This is in preparation for the large pre-cast concrete roofing structures which will be delivered and installed in January.
The second month of the Christie Ave Wastewater Pump Station upgrade project saw the rising main (pipeline) be installed along Christie Ave, and up Mutu Street to the bridge. We also poured the concrete floor of the large holding tank, with the new walls being poured early in December. Work is continuing at the Mutu street bridge, linking the new pipeline to Christie Avenue.

This month we began excavating for the large underground storage tank at the front of Christie Ave Pump Station (pictured behind in green). Great progress has been made, with the new pit lined in preparation for the new tank to be placed in December.
The Christie Avenue Wastewater Pump Station was built in the 1970s, and was initially built as a booster pump station. Minor upgrades have been previously undertaken however with Te Awamutu and surround growing population projections, it is essential that we upgrade the current infrastructure to cope with increasing demands.
In peak wet weather events, the pressure on the wastewater network increases and staff are currently required to manually switch between two pump station sites to manage wastewater flows. This is not the most efficient operation.
The upgrade has been identified as future requirement for a number of years, however it was brought forward in 2019 due to the timing of the Waikeria Wastewater pipeline project. Chrisie Ave Wastewater pump station requires an essential upgrade in order for the network to address increased capacity and efficiency requirements for our growing district.
