The Alkimos WWTP is located approximately 40 km north of Perth and serves the rapidly expanding northern suburbs.
The plant will be developed in stages during the next 80 years, and will ultimately serve a population of 750,000 people with a total expected inflow of 160,000 m³/d. The wastewater is being transported to the WWTP with a 5 km long DN 2000 tunnel. After treatment, water is evacuated to ocean via a 4 km sea outfall.
