Waipukurau Water SH2 Bore Upgrade

This project focuses on the bores at the SH2 water borefield that supplies Pukeora reservoir and Waipukurau.

This includes improving and refurbishing 3 bores, installing pipework, electrical work, fencing and a tank for extra water. These upgrades mean closer compliance with Drinking Water Standard New Zealand (DWSNZ).


Update | January 2022

Last week saw a successful rechecking of the 3 new Bore Pumps that we plan to bring online over the coming couple of months. This week, the Operations Team will continue flushing of the new bores in readiness for changing over to the new bores in early February.

During February, there is work to be carried out by Max Tarr’s team to change the location and power source for the Existing Bore A and Genset plus some auxiliary items from the original upgrade project.

Update |15 November 2021

All power and control cabling have been installed to the Run to Waste off takes. Thrust blocks are installed allowing back filling of trenches to be completed this week. The contractors;  Max Tarr will complete the physical works this week with the control system with the next job being the testing/commissioning of the system prior to the Christmas break.


SH2 Borefield

Update | 18 October 2021

Max Tarr Ltd are on site to construct the Run to Waste discharge system for the Waipukurau Borefield. This system will allow turbid water to be discharged back into the river. This week will see the section of pipe under the stop bank be installed by directional drilling, rather than open cut excavation through the stop bank.

Update | 6 July 2020

The project team continue to chip away at this project, last week the Flow Meter and Flow Test Rig were installed on the Existing Bore A Outlet Pipe. This allows actual flow monitoring off the largest pump and bore onsite, and the flow rig allows for 5 yearly calibration to comply with our resource consent.

The New Pumps for Bores D and E have arrived in the country and are currently in transit to Palmerston North to Max Tarr Workshop to be prepared for installation later this month.

Update | 15 June 2020

Last week we commissioned Bore B into the network, and over the next few weeks we will tweak how this Bore/ Pump works with our main Bore A pump. This will now allow us to progress with setting up the new Bores D and E, to allow their new pumps to be installed.

Update | 2 June 2020

We are preparing for the commissioning of bore B – which is scheduled to take place on the 9th June. In the interim, on site we are installing permanent fencing, and the shed frame is going up around our new pump for Bore B. Exciting times, we can then begin to remove reliance on the old syphon vacuum pump system.

Update | 18 May 2020

The works at the borefield continues to progress well, with our contractor continuing to install new pipework and configure one of the new bores/ pumps for operation, we are on track to reach a further milestone on the project this week with the commissioning of the new transformer, which will increase the power capacity to the site and allow the new controls to run the new pump in the bore.

Sh2 Borefield Transformer and Control Shed

Update | 16 March 2020

The project has made great progress in recent weeks with the key piece of new pipework installed into the network, that allows all the new bores to be connected. We forge ahead and expect to have majority of the work complete in June 2020, with one of the new pumps in action.

SH2 Borefield new pipe

Update | 5 March 2020

The shut down last night was successful, and we have installed the new manifold into the network.

The team of Max Tarr, Veolia and Centralines worked well together to install the new pipes and structures in good time, to allow the supply to be restored in time for the usual morning peak use.

1007 SH2 Bore Field DN250 Manifold 20200304 7

Update | 4 March 2020

Tonight we carry out a shut down of the supply from the borefield up to the reservoir to allow a new section of pipe to be installed that will facilitate the integration of the new bores into the supply.

The shut down is planned from 11pm through to 5am tomorrow morning.

There will be no water supply impact to residents. We need to undertake the work in the period of low use, to minimise the draw down on the reservoir through low peak water use throughout the shutdown. We will monitor levels and at 4am/5am upon completion we will restore supply and the reservoir will fill again and we will revert to normal operation.

The homes up on Pukeora reservoir will be without power throughout the shutdown. As centralines isolate power at the borefield for safety as we use cranes to install pipes and structures into the network.

There will be minor noise as we run our generator at the reservoir. All affected parties have been notified by council and Centralines.

Update | 2 March 2020

Last week we installed the new pump into Bore B, and work on installing the pipework from this bore into the main line for connection. a shut down of the line is planned for the night of 4th March 2020 to install a section of pipework to facilitate future connections of the new bores.

SH2 Borefield Bore B with new Pump

Update | 26 Feb 2020

We are currently preparing the new bores drilled (Bore D and E) for their pipework, and have poured the concrete aprons around the bores. 

The new pumps are being ordered, and the project continues to make good progress.

Update | 21 Feb 2020

The extension of the electrical control room is nearing completion and the new switch gear and controls are currently being installed.

IMG 20200302 103145

Update | 14 Feb 2020

This week we successfully installed an air valve on the existing main that runs from the borefield to the treatment plant and the reservoir.

This was a complex task, involving the shut down of the reservoir and the water supply, undertaken at night between 11pm and 4am to minimise disruption and to ensure the lowest demand possible is on the network.

This air valve acts as a key pressure release instrument on the pipeline, to ensure that once the upgraded pumps and bores are operational, the pipeline isn't under any additional stress or risks fracturing.

Update | 11 Feb 2020

Final pump testing is underway for the new bores this week, this will inform us on the quantity of water each bore may be able to sustain and supply for long periods without significant draw down. Once we have this information, we can the order the right sized pumps to supply water to the reservoir and treatment plant prior to being sent to Waipukurau residents.
