We're rolling out Stage 2 of the Groundwater Replenishment Scheme, which involves constructing a second Advanced Water Recycling Plant at the Beenyup facility, drilling new bores for recharge and monitoring and building a new 13km pipeline.
To expand the scheme we will:
- build a second Advanced Water Recycling Plant at the Beenyup facility in Craigie
- drill four new recharge bores and four new monitoring bores in Wanneroo and Neerabup
- build a 13km recharge pipeline connecting the Advanced Water Recycling Plant with the new bores.
Where is this happening?
The second plant will be located next to the original plant in Craigie and when complete, the two will share some infrastructure.
Below is a map depicting the pipeline route and recharge bore sites.

Why is this work taking place?
Due the impacts of climate change on Perth, a decision was made in July 2016 to expand our Groundwater Replenishment Scheme. This Scheme provides a new climate-independent water source to boost much needed drinking water supplies in Perth.
The expansion from Stage 2 will provide better certainty for Perth's water supplies, with the Scheme's capacity increasing from 14 billion litres per year to 28 billion litres a year.
When is this happening?
Expanding the scheme started in late 2017, when we started building the new Advanced Water Recycling Plant. We expect the plant will be complete in 2019. In 2018 we drilled the recharge and monitoring bores and in 2019 we will build tanks and other infrastructure at the recharge sites in Wanneroo and Neerabup.
We started building the pipeline in Woodvale in 2018. The pipeline is expected to be finished in mid-2019.
How will this impact the community?
Construction work can have local impacts, including noise, dust, traffic management and vibration. Before we start work in an area we notify the surrounding community.

A 13km recharge pipeline will transfer the highly treated, drinking quality recycled water from the Advanced Water Recycling Plant in Craigie to the offsite recharge bores.
The pipeline is being constructed in sections using different construction techniques. The first two sections of pipeline, installed using trenchless technology (horizontal direction drilling), was completed in the second half of 2018 and were located beneath banksia woodlands in Wanneroo and Perry’s Paddock, Beenyup Swamp and Studmaster Park in Woodvale and Wanneroo. This construction technique was selected to reduce the impact on these environmentally-sensitive areas.
The remaining sections of pipeline are being installed through Neerabup and Woodvale using open trench construction techniques, beneath the Mitchell Freeway to the Advanced Water Recycling Plant using trenchless technology (micro-tunnelling). These sections are expected to be completed by early 2019.
Future sections of the pipeline include crossing beneath Joondalup Drive, which will be managed by Main Roads WA as part of its Joondalup Drive and Wanneroo Road intersection upgrade work.
