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.

Note:

There will be no works between 20 December 2017 and 1 February 2018.

Traffic Delays are Possible

The road will be open at all times. However, traffic will be reduced to one-lane on sections of the road with stop-go traffic management in place. 

We appreciate that these works will be disruptive and create delays on the Riwaka-Kaiteriteri Road. Our priority is to minimise disruption to residents, cyclists, road users and businesses.

Tasman’s Great Taste Trail will stay open throughout the works, but some parts will be affected from time to time.

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.

The new wastewater pipeline will be installed along the road reserve from Stephens Bay to the cycleway access at the intersection of Kaiteriteri Road and Goodall Road in Riwaka.

There will be some new pipes in Stephens Bay Road, Anarewa Cresent and Tapu Place. The 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.

Timeline

Work will be staged over two years to avoid disruption during the peak summer period.

Up to 20 December 2017

  • A new sewer main will be installed along the road reserve between Stephens Bay, Kaiteriteri, and the Ted Reed Reserve at the intersection of Kaiteriteri Road and Goodall Road in Riwaka. Installation will progress in stages from the corner of Cederman Drive and Riwaka-Kaiteriteri Road towards Riwaka.
  • This will include a new sewer pipe from the Stephens Bay pump station to the main Kaiteriteri-Riwaka Road.
  • Work began on the corner of Cederman Drive and Riwaka-Kaiteriteri Road and will progress in stages towards Riwaka. 
  • Traffic will be reduced to one-lane on sections of the road as works progress.

Between February and July 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 be flushed and sealed.

Progress

Work started on April 20 and is and is progressing on time and to plan.  The major work to install the pipeline in the Riwaka-Kaiteriteri Road is planned to be completed mid November.  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.

Work will pause over Christmas.  In the new year 2018 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. 

A second team of contractors are working on the control valves just before the Stephens Bay-Tapu Bay settlement.

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.
