October 2016

Work along Brook Street has now started with minor work being done to re-align existing water and sewer infrastructure. This work is being done using a shoulder closed traffic management plan to reduce disruption. The closure of Brook Street originally planned for 10 October will now begin on 17 October (one week later). The aim is to reduce overall disruption to traffic along Brook Street by allowing various preliminary works to be completed before closing Brook Street itself.

December 2015:

 Tenders closed 5 November 2015 and are now going through the approval process. Resource Consent has been approved and  construction is  programmed to commence February 2016. Work expected  to take around 7 months.


A safe and reliable water supply is essential to the well being and sustainability of our community. A long-term project to improve water pipeline security from the dam to the city is being undertaken over many years, the most recent stage being the duplication of the section of pipeline from the dam to the treatment plant, completed in 2014, which now provides a more secure supply line to the treatment plant.

The next stage of future proofing our water supply is to build a duplicate supply line from the treatment plant to Brook Street. This section of pipeline was damaged in the 2008 wind storm and is now a high priority project. This work was originally programmed for 2020/21 but has been brought forward as a result of the Christchurch earthquakes.  After assessment of options for proposed route, the detailed design work took place in 2014/15. Construction is scheduled to in mid May 2016.
