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.

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.

Construction impacts

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.
