Water Thought Leaders Series: Innovation and Sustainability Through Groundwater Replenishment

Start time: 2.00 pm AEDT. Explore the innovations behind Groundwater replenishment and Advanced Water Recycling Plants, and the sustainable benefits of this climate-independant source.
Water Thought Leaders Series: Innovation and Sustainability Through Groundwater Replenishment

Traditionally Perth has relied heavily on rainfall as a primary water source. 

In recent decades this has been impacted by the effects of climate change, which has presented significant environmental, social and economic challenges, including how to maintain the supply of quality drinking water for a growing city.

Groundwater replenishment is the process by which secondary-treated wastewater undergoes advanced treatment at an Advanced Water Recycling Plant to produce drinking-quality water. 

Join us on Wednesday 21st October, as Lisa Chan, Engineering Manager, WA (SUEZ Australia) and Nick Turner, Senior Principal of Strategic Programs (Water Corporation) discuss the innovations behind Groundwater replenishment and Advanced Water Recycling Plants.

Our speakers will explore the benefits of the water supply derived from a sustainable and climate-independent source, how these methods are the preferred sustainable source of recycling­­­ treated wastewater, and outline their findings through the use of the Groundwater Replenishment Scheme - Stage 2 as the main case study.

This project is Australia’s first full-scale Groundwater Replenishment Scheme and was completed in early 2020. The Stage 2 expansion doubled capacity to 28 billion litres of water per year, and required both onsite and offsite infrastructure comprising of;

  • A second Advanced Water Recycling Plant
  • Four recharge bores and four monitoring bores across two recharge sites accessing Perth’s deepest aquifers – the Leederville and Yarragadee aquifers
  • A 13-kilometre pipeline extending north-east from Craigie, to transfer the drinking-quality water from the plant to the recharge bores.

This expansion project presented significant engineering and environmental challenges successfully overcome through innovative design and a high standard of project management.

Key Themes

  • Reduce environmental impact through innovative design 
  • Best practice in sustainable and climate-independent groundwater allocation
  • Local case study: Groundwater replenishment scheme – Stage 2
