Following the successful Groundwater Replenishment Trial, Stage 1 of Perth's first full-scale Groundwater Replenishment Scheme began recharging at our facility in Craigie in late-2017.
This first stage has the capacity to recharge 14 billion litres of recycled water into groundwater supplies each year.
Construction of Stage 2 of the Scheme also began in late-2017, following receipt of environmental approvals. Stage 2 work includes:
• duplication of the Advanced Water Recycling Plant in Craigie
• four recharge and four monitoring bores across two offsite recharge locations in Wanneroo and Neerabup
• a 13km recharge pipeline connecting the Advanced Water Recycling Plant with the bores.
When Stage 2 is complete in 2019, the Groundwater Replenishment Scheme will have the capacity to recharge 28 billion litres of water each year, providing a new climate independent water source to boost much needed drinking water supplies in Perth.

Advanced Water Recycling Plant
Construction of the second Advanced Water Recycling Plant began in late-2017. The second plant will be located next to the original plant and when complete, the two will share some infrastructure, including two new 13.7 megalitre tanks that will transfer secondary treated wastewater from the neighbouring Beenyup Wastewater Treatment Plant.
Construction is expected to be complete in 2019, followed by commissioning, testing and validation. Recharge under Stage 2 of the Groundwater Replenishment Scheme is expected to begin in late-2019.
Recharge bore sites
Water from Stage 2 of the Groundwater Replenishment Scheme will be recharged into the confined Leederville and Yarragadee aquifers via two recharge sites located north-east of the Advanced Water Recycling Plant, in Wanneroo and Neerabup.
The bores have been constructed and work has begun with the installation of above-ground bore infrastructure, including a recycled water tank and a pump and electrical building at each site.These works are planned for completion by April 2019.
The Wanneroo site is located within an existing cleared area in the pine plantation off Ashley Road and Wanneroo Road. Drilling of these bores began in late-2017 and was undertaken in stages, finishing in October 2018.
The Neerabup site is located within land owned by Water Corporation off Wanneroo Road. Drilling of these bores began in mid-2018 and was also undertaken in stages, finishing in November 2018.

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, and along the eastern side of Lake Joondalup in Wanneroo following the Rainbow Bee Eater nesting season.
