Kaiteriteri Replacement Sewer Main

This page provides details about a project to replace the sewer pipeline from Stephens Bay, Kaiteriteri to Riwaka, and to upgrade the Stephens Bay and Tapu Bay pump stations and associated pipelines.

Construction is under way and will run through to July 2018.

About the Project

To cater for future population growth in Kaiteriteri and to better manage the large population increases during summer, we are installing a new sewer main from Stephens Bay, Kaiteriteri to Riwaka, and upgrading the Stephens Bay and Tapu Bay pump stations and associated pipelines.

Currently wastewater from the Kaiteriteri settlements is pumped to Motueka Waste Water Treatment Plant through a pipeline under Tapu Bay estuary. This project changes the network so that wastewater is pumped through a new pipeline in the Kaiteriteri-Riwaka Road.  This means the estuary pipeline can be abandoned.  This change means the Tapu Bay and Stephens Bay pump stations need to be reconfigured to send wastewater to the new road pipeline.

In 2017 the new 250mm diameter wastewater pipeline was installed along the road reserve from Stephens Bay to the cycleway access at the intersection of Kaiteriteri Road and Goodall Road in Riwaka.

Work in 2018 will mostly be in Stephens Bay Road, Anarewa Cresent and Tapu Place. The main works will be upgrades to the Tapu Bay and Stephens Bay pump stations.  A new pipeline between Tapu Bay and Stephens Bay Road will be installed inside the existing pipeline, which means we won’t need to dig a trench in the road.

The current pipeline will remain in the estuary. When the new pipeline becomes operational, it will be flushed and sealed to avoid any leaks.

  • From February to June 2018, the Stephens Bay and Tapu Bay pump stations will be upgraded and minor works will occur in Stephens Bay Road, Anarewa Crescent and Tapu Place.
  • The existing sewer pipe will also be flushed and sealed.
  • The Council will also be taking the opportunity to make some improvements to the wider Kaiteriteri wastewater network as part of this project. This includes improvements to the Martin's Farm pump station and Little Kaiteriteri pump station.

Work started in 2017 and is progressing on time and to plan. The major work to install the pipeline in the Riwaka-Kaiteriteri Road is complete. There will be minor work in the road to install air valves and drain points.  Disruption for road and cycle trail users during these minor works will be minimal.

This year work will start on upgrading the two pump stations in Stephens Bay and Tapu Bay.  We will provide more detail about this work programme in the new year.

Donaldson Civil will letter-drop properties affected approximately 10 working days prior to work beginning outside their properties. 

Design and Cultural Advice

The design (prepared by Tonkin & Taylor) considers reconfiguration of the pump stations, the local geology and key cultural and historical sites. Resource Consents and a Heritage New Zealand archaeological authority have been granted.

Tiakina te Taiao and local iwi are advising on cultural issues.

Donaldson Civil was awarded the contract to construct the new pipeline in Riwaka-Kaiteriteri Road and to upgrade the wastewater pump stations at Stephens Bay and Tapu Bay.
