Toronto Wastewater Treatment Works Upgrade
We’re investing over $10 million to upgrade the Toronto Wastewater Treatment Works to safely and reliably meet local population growth, reduce odour and protect the environment.
Location: Faucett Street, Blackalls Park
Project Duration: Mid-2021 to mid-2024
Investment Value: $10.1 million
About the treatment works
Built in 1992, the Toronto Wastewater Treatment Works (WWTW) serves the area from Teralba to Wangi Wangi on the western side of Lake Macquarie, including the townships of Marmong Point, Bolton Point, Toronto and Rathmines.
It currently treats 6 megalitres per day and can handle wastewater from a population of up to 42,000 people.
Why the work is needed
The treatment works needs to be upgraded to ensure it can continue to reliably service the local community into the future. The upgrade will increase the capacity and performance of the treatment works to reduce odour issues and ensure it meets modern safety and environmental standards.
The upgrade will also enable us to recycle effluent for use onsite, reducing our reliance on drinking water to service the plant’s process unit requirements.
What we're doing
The work includes:
- upgrading the plant’s high voltage electrical equipment
- upgrading the odour control facility
- installing a new recycled effluent system for onsite use
- upgrading the plant’s control and communication system
- upgrading the aeration tanks and blowers equipment.
- August 2021: High voltage upgrade begins (Stage 1)
- February 2022: Odour control facility upgrade, recycled effluent system, and plant’s control system installation begins (Stage 2)
- April 2023: Aeration tank upgrade begins (Stage 3)
- Mid 2024: Project completion
The work will be carried out within and around the existing treatment works site on Faucett Street, Blackalls Park. The construction will have minimal impact on the local community and neighbours will be advised before any work begins.
The plant will be operational throughout construction to ensure the wastewater service is maintained.
