The Altona Treatment Plant (ATP) treats close to 13 million litres of sewerage a day from more than 20,000 homes and businesses.
Most of the wastewater captured at the plant is treated and used in manufacturing and for watering of golf courses and recreation reserves. Some of the wastewater from this process is discharged into Port Phillip Bay under strict regulatory conditions.
What is happening and when
To ensure that the plant continues to operate reliably and effectively, we are undertaking essential maintenance work on one of the three diffuser tanks.
This involves draining and cleaning the tank and replacing internal components.
Wastewater that would usually be stored in the tank will be temporarily stored within the treatment plant lagoon and treated wastewater will be discharged into Port Phillip Bay.
If we delay the works, the treatment quality and wastewater discharged will continue to decline.
Work will commence Monday 4 October and take approximately 8-10 weeks to complete.
