Nannup Standby Bore

What is happening?

Water Corporation is planning upgrades to the Warren–Blackwood Regional Water Supply Scheme over the coming years to improve its reliability and efficiency.

As part of this work, we have recently constructed a new standby bore at our Thomas Road site in Nannup, approximately 300 metres from the existing bore. The next stage of this work involves testing the new bore to confirm it is operating as designed.

Following testing, the new bore will remain offline until a future stage of the project, when it is connected to the water supply scheme.

We will soon undertake bore testing at the new standby bore. This work will be completed by our authorised contractor, Global Groundwater.

The bore test involves pumping water from the bore to assess bore performance and confirm the infrastructure is operating as expected.

When is this happening?

This work is expected to commence from Monday 14th September 2026. It is expected to take up to fourteen days to complete, although may be completed earlier. 

Work will occur between 7:00am and 7:00pm, Monday to Sunday, including public holidays.

Upcoming Night Work 

As part of this work, we need to complete a period of continuous 24-hour pump testing to accurately assess the bore's performance over an extended period. This requires the pumping equipment to remain operational overnight.

As a result, work will continue outside standard hours between 7:00pm and 7:00am on Monday 21, Tuesday 22 and Wednesday 23 September 2026.

During this work, a sound attenuation barrier will be installed. We will make every effort to minimise sound impacts on nearby properties while this testing is undertaken. 

• Work hours: Work will take place between 7:00am and 7:00pm, Monday to Sunday, including public holidays. 

• Night work: Night work will take place from 7:00pm to 7:00am on Monday 21, Tuesday 22 and Wednesday 23 September 2026.

• Sound: A generator will be required on site during the work. To reduce noise, a sound attenuation barrier will be installed around the generator. We will continue to take all reasonable steps to minimise sound impacts wherever possible.

• Water release: During the work, water from the bore will be released to the surrounding environment in accordance with regulatory approvals. The water does not contain harmful chemicals; however, it may contain slightly elevated levels of naturally occurring minerals.

We thank you for your patience and understanding while we complete this work. 

Why is this happening?

The new standby bore will help support a reliable water supply for the region.

Once connected to the scheme, the new bore will operate alternately with the current one, enabling routine maintenance without service interruptions and providing a backup supply in the event of bore failure.

Following completion of testing, the standby bore will remain offline until a future stage of the project, when it is connected to the water supply scheme.

What else is planned?

Removal of the temporary settling pond is currently expected to occur between mid-October and late November 2026 and is anticipated to take approximately four weeks to complete. Further information will be provided before this work begins.
