Waipukurau Water SH2 Bore Upgrade
The new bores are currently under development as we clear them ready for the pumps to be installed, over the next few weeks we pump test the bores to understand their capacity.
The new transformer was installed yesterday on site, and is now ready for commissioning once the electrical control room is complete.
This week we continue to work on preparing the borefield for the new pipework to be installed.
The transformer is also planned to be installed on site on Wed 18th December - ready to be turned on when the electrical room is equipped.
The screens have arrived and we commence installing them into the bores this week.
The temporary bypass has been cut in allowing the transformer work to continue and the above ground pipework to be removed from Bore C.
Work has also begun on the building extension this week.
The project continues to progress, with the site temporary fenced.
Excavation has started on site to identify services and confirm the pipe layout, the team is also planning a temporary bypass to allow the removal of a section of above ground pipe.
Tomorrow 20th Nov, Centralines commence work on site to install the pad for the new transformer.
The following week, we are planning a shut down to install a new stainless steel manifold with off takes to allow the new bores and Bore B to be connected in at a later date.
Both bores are drilled to a depth of 8mtrs.
The screens to be installed in the bores are on order, and we expect to have the bores developed by the Xmas break, awaiting their pumps.
Bore drilling is going well, with one new bore in place at 8m deep, and the other approx. 6m deep at the moment, and expected to be completed this week. We can then install the screens and start pump testing. Other works also progress well, and our building shed extension is planned to start in a few weeks along with the power upgrades, and pipeline installation.
After a few weeks of poor weather - we are into the drilling of the new bores at our SH2 Borefield site this week.
These are to replace two aged bores, in preparation for our upgrade of the site with new pumps, electrical controls, automation, meters, and pipeworks replacement. Work is expected to take three weeks to drill these new bores.
Other components of the project continue to progress, with Centralines on site after labour weekend to start with the transformer upgrade and relocation.
Bore drilling is to commence on site from early October 2019 for a period of 3 weeks to replace two bores, works is also expected to take place in mid Oct 2019 by Centralines to upgrade the current overhead 200kva transformer to a pad mounted 500 kva transformer.
A new Pump for Bore B is on order, and the works required to replace Bore D and E is scheduled for Sep 2019.
The electrical design and shed extension is under review.
The project continues to progress with its many facets, and council is working towards a late Dec 2019 completion.
Council has awarded a contract to Max Tarr Ltd in conjunction with WSP-Opus to deliver this key project.
Works and planning are currently underway, with the following key items in progress;
- Camera assessments of the bores
- Relocation and upgrade of the in-situ transformer with Centralines
- Building extension to house the upgraded controls
- Fencing changes
Physical works is expected to commence onsite in Aug 2019, trenching in new pipelines, extending the building housing the controls, and general civil works.
This project has progressed to contract negotiations, and Council expects to have awarded a contract and finalised a programme by early July 2019.
This week, did mark a milestone for works to progress with the re-installation of 'pump A' , this adds resilience back to the borefield and the project team can now focus, on finalising the works to upgrade Bores B, C, D and E.
Council still expects works to take approx 4 months, and be completed by December 2019.
This project is currently under tender and Council expect to have awarded a contract to our preferred supplier in May 2019.
There have been some delays to the works programme due to the unexpected failure of the main Pump 'A' at this borefield. Council expects works to take approx 4 months, and be completed by December 2019.
On completion, there will be four lineshaft pumps including Pump 'A' with the ability to variably pump water to the Pukeora reservoir.
The design aspect of this project is progressing well, council is currently finalising the design and pipe layout and plans to tender this work out in Feb/ March 2019.
Council has a project to upgrade the bores that supply water to the Pukeora reservoir and the township of Waipukurau. A number of the pumps are nearing end of life and require replacement.
Council is also taking the opportunity to upgrade the electrical control system and install flow and turbidity meters on all bores to assist with the maintenance and drinking water standard (DWS) compliance.
Council is currently finalising the detailed design, and is aiming to tender the works out in early 2019 for physical completion by 30 June 2019.
Further updates will be provided as the project progresses.
