Pōrangahau Water Treatment Improvement

Porangahau Water Treatment Improvement


Porangahau and Te Paerahi's new water reservoir is up and running, adding 184,000 litres of water storage to the network! This is double the capacity of what the townships had previously, which will be a huge help during peak summer months when visitor numbers to Porangahau and Te Paerahi rise dramatically. Check out this fantastic timelapse video, which shows the build of the reservoir in action. Alongside the reservoir, Central Hawke's Bay District Council have also commissioned a new Water Treatment Plant for the area, which works through known issues of iron and hardness, and ensures consistency and compliance with drinking water standards, while meeting community water demands. We'll be coming together to formally open the Water Treatment Plant and reservoir on 18th March at 4.00pm and we'd love for the community to join us. For event details see:

Update - 27 January 2020

On Friday the 24th we completed the reservoir and this week we work on connecting the reservoir to the treatment plant, and commence testing of the new reservoir. 

The reservoir will add 184cm3 or 184,000 litres of water storage to the network, helping to relieve the demand on the treatment plant and network in peak months.

Update - 18 November 2019

The team continues to hook in the new containerized system to the pipework recently installed, this week we also plan to relocate the raw water line that runs from the bore to the water treatment plant. This will make room for the pad to go down where the new water reservoir will be erected.

Update - 04 November 2019

We reached a big milestone in this project on Fri 1 Nov, with the containers being delivered to site and positioned ready to have all the new pipework connected.

We will working away over the next 6 weeks getting the site ready for commissioning before Christmas.

Outside of this, we are pleased to award Higgins a small contract to extend the backwash discharge pipeline approx. 700m from the treatment plant to the wastewater network, this work will start shortly, and aim to be complete mid December 2019, to line up with the commissioning of the water treatment plant. The additional storage project progresses well and we are finalising the storage design, and plan to start civil works in preparation for the reservoirs construction to start in Dec 2019.

Update - 18 September 2019

Cabling and duct install work is underway and is expected to be completed by the end of the next week.

Council is making good progress with the landowners to deliver additional storage with the successful funding received through the tourism infrastructure fund.

Work involved with this project are a large 195cm3 reservoir, acquisition of additional land behind the current plant, pipework and cabling to the reservoir, felling of trees to make room for the new reservoir and to safe guard the reservoir and new plant from future damage.

All going well this reservoir will be operational from early 2020.

Council is also working with Veolia to develop the storage options to be delivered through our successful TIF application.

Update - 21 June 2019

The project continues to progress well, early June 2019 saw the completion of the detailed design for this project, the teams focus now shifts to completing final planning items before construction commences on site.

Crews are due to commence civil and earthworks on site at the end of June/ early July 2019 in preparation for the concrete foundation to be laid for the pre-fabricated containers to be delivered to site in August 2019. The containers will house the new equipment in addition to the upgrades taking place in the existing housing structures on site to provide the treatment and processes required to consistently meet DWSNZ moving forward.
