Proposal to pump 70m litres of treated wastewater into Parramatta River
If approved, a Sydney facility will pump millions of litres of treated wastewater, equivalent to 35 Olympic-sized swimming pools, into Parramatta River per day to service a growing population.
Sydney Water is proposing a wastewater treatment facility at Camellia-Rosehill that would discharge 70 million litres of treated wastewater into the Parramatta River daily. The proposal, which has garnered over 400 public submissions, aims to address capacity issues with existing infrastructure. If approved, construction is expected to commence in 2028 and conclude in 2032.
Despite the proposal to improve water quality, concerns have been raised regarding potential environmental and wildlife impacts. Sydney Water asserts that the highly treated wastewater would be cleaner than the river's current water, but former Sydney Water scientist Ian Wright expresses skepticism about the reliability of treating wastewater reliably.
The project's environmental impact assessment is being conducted by the Department of Planning, Housing and Infrastructure.
