Te Anau wastewater upgrades | Hamilton City Council

Project summary

Hamilton’s wastewater network is under pressure. The western network is at capacity, which means during heavy rain, there’s a higher risk of overflows into our environment.

This project focuses on core infrastructure improvements to:

reduce wet-weather overflows
ensure our existing water network can operate safely and reliably
support residential development in Glenview and Fitzroy
protect the Waikato River and meet obligations under Te Ture Whaimana o Te Awa o Waikato

What we're doing

Upgrading the Te Anau wastewater pump station.
Installing a new wastewater pipeline (and re-using an existing abandoned water pipe).
Redirecting wastewater flows from the Te Anau and Splitt wastewater pump stations to the Peacocke wastewater transfer station.

Frequently asked questions

Will there be traffic disruptions?

Yes, temporary traffic management will be in place during construction. This may include detours, or reduced access on certain roads. We’ll provide advance notice and signage to help you plan ahead.

Will construction affect access to my driveway or property?

In some cases, access may be temporarily restricted. We’ll work with you to minimise disruption, and restore access as quickly as possible.

How will I know when work is happening near my property?

You’ll receive a letter before construction begins near your home. You can also stay informed by signing up for project updates using the form above.

Will my water or wastewater services be interrupted?

No. Your water and wastewater services will continue as normal. If any planned service interruptions are required, affected residents will be notified in advance.

Will there be noise, vibration, or dust during construction?

Yes, you may notice noise from machinery and trenching activities. Contractors will follow approved noise management plans to reduce disruption, and work will generally take place during daytime hours.

Some vibration and dust are expected during trenching and drilling. Environmental and safety management plans will be followed to minimise these impacts.
