M22-M46 Mitcham to Syndal water mains renewal

In Melbourne, water is essential to our way of life. Clean, affordable water is readily available to our homes and businesses whenever we need it, via a network of underground water mains. Over time, these mains age and need replacing. That's why, at Melbourne Water, we are undertaking water main upgrade works across Melbourne’s eastern and southeastern suburbs. These upgrades will ensure we can continue to supply our customers and the wider community with a safe and reliable water supply today, tomorrow and for generations to come.

About the project

Melbourne Water has replaced three aging sections of the M22 and M46 water mains between Mitcham and Syndal.

Replacement works included:

Replacing sections of the M22 and M46 water mains and installing a single new 1.15-1.35m diameter water main between:
- Mitcham Reservoir to the intersection of Springvale and Canterbury Road, Forest Hill.
- The intersection of Hawthorn and Mahoneys Road to Aston Court, Burwood East.
- Cherry Street to High Street Road, Glen Waverley.
Abandoning a section of the M22 water main between the Waverley Road Basin and the Monash Freeway, Mt Waverley.

Why is this project needed?

The M22 and M46 water mains are 90 to 100 years old, with the M46 built in 1912 and M22 in 1927. Sections of the M22 and M46 water mains were nearing the end of their service life.

This work ensures Melbourne Water can continue to supply our customers and the wider community with a safe and reliable water supply now and into the future.

Project timeline

The project is currently in the detailed design phase. Construction works are planned to commence in early to mid-2022 and take 12 to 18 months to complete.
