Nilgen replacement water main

back to current projects

Project goal:

To improve the reliability of water supply to customers in Nilgen's Ocean Farm Estate (Stage 1)


In construction

Delivery Date:

March - end of August 2018

What's happening?

Water Corporation will begin work in early March to replace approximately 14 kilometres of existing buried water main with Ocean Farm Estate (Stage 1) in Nilgen. This upgrade will improve the reliability of water supply to customers in this estate.

The work will involve constructing new water pipes within the road reserve in the estate and bore pumping main to the existing water tanks at the corner of Ocean Farm Drive and Christmas Tree Drive. It will be completed by digging an open trench using an excavator or trenching machine, laying the new water main and then backfilling the trench.

Community impact

Upcoming planned interruption to water supply to customers in Nilgen:

On Thursday 31 May, 2018, all customers in Nilgen will experience a temporary interruption between 9am and 3pm, whilst we connect the newly installed pipeline to the existing water supply service.

We advise customers to plan for this period when water may be unavailable for up to six hours.

Please view this information for further details about this planned water supply interruption.

Special circumstances: If you have any special circumstances we need to be aware of before this essential work starts, please contact Elecia Wheat, Advisor – Community Engagement on (08) 9420 3265 or via email at

During May 2018, the following activities will take place:

  • Construction is now over half way complete.

  • Surveyors will continue to work with service locators and peg out the remaining replacement pipeline route and pothole the existing underground services along this route. Any required vegetation clearing will also take place along the pipeline alignment.

  • The construction crew will progress with constructing the replacement pipe along Ocean Farm Drive, Craig Sandy Way, Ocean View Rise, Blackboy Drive, Parrotbush Road and Kangaroo Way.
  • The construction crew will start constructing the replacement pipework from the Water Corporation bore on Ocean Farm Drive to the water supply tanks and then following this, throughout the estate, as described above. We will provide customers with another update at this time before we start construction within the estate.

Local residents in these areas should expect medium-level noise from trucks and plant, excavator or trenching machine digging excavations, with minimal dust and vibration. We also request that road verges be kept clear over this period.

Overall impacts:

When we connect the replacement reticulation main to the scheme, customers will experience a temporary interruption to supply, however we will provide advanced notice of this activity.

Traffic management will be in place and road users will be asked to keep to the reduced speed limit, which will be indicated through signage in these areas.


This work is expected to start in March and be completed by the end of August 2018. Work is expected to take place on Mondays to Saturdays from 7am - 6pm.
