Te Maunga Wastewater Treatment Plant – Final Effluent Line and Bypass Pipeline

Deliver, but don’t disrupt. A complex challenge.

When asked to install a new effluent pipeline for the Te Maunga Wastewater Treatment plant, we were tasked with completing the project with zero disruption – the effluent line could not be shut down under any circumstances. All cutovers or connections needed to be completed within very short timeframes under technical overpumping operations.

To achieve this challenge, we worked in close partnership with Tauranga City Council, suggested more cost-effective options, and deployed all of our local knowledge and experience with Te Maunga to complete the project with zero disruption or incident.

Our work
Installation of 1,200 metres of new PE pipeline.

Removal and disposal of 250 metres of RCRRJ pipe.

Removal and disposal of 400 metres of asbestos cement pipe.

Construction of approximately 400 metres of timber retaining wall.

Services location and relocation into a common services trench, including around 1,200 metres of 11 kV cable and other utility services.

Reinstatement of the road, including pavement construction, kerb and channel, and surfacing (AC and chipseal).

Council project manager commented that the project team and delivery “felt like a partnership”.
