Notice of application for renewal of Mill Stream authorisation

Sydney Water has re-applied for authorisation to periodically discharge diluted wastewater overflows during wet weather into Mill Stream at Sydney Airport. This authorisation is required because discharges can exceed accepted limits for water pollution as described in the Airports (Environment Protection) Regulations 1997. The authorisation is sought for the period to 31 March 2027.

Sydney Water is working to reduce the occurrence and impact of discharges, including clean ups after all overflows, desilting wastewater pipes, reducing stormwater inflow to the wastewater system, and solids screening. Planning for longer term solutions is also being advanced. All activities are included in Sydney Water’s Mill Stream Environmental Management Plan (EMP).

You may post your written submissions by 21 January 2024 to:
