Melbourne Water undertakes trenchless sewer projects

After the successful completion of the Merri Creek Sewer Rehabilitation Project, the utility has a number of other trenchless projects planned, including the Brighton Main Sewer Rehabilitation Project and the Williamstown Main Sewer Rehabilitation Project.

The Brighton Main Sewer has been servicing the Brighton and Hampton areas since 1907, and the rehabilitation is set to extend the sewer’s service life for another fifty years.

The project is currently in the design phase, with 4.6 km of relining activities planned to take place along St Kilda Street, Esplanade, and Beach Road, from Brighton to Hampton.

Planned works also include operational improvements for flow monitoring and control, and manhole repair and rehabilitation.

In order to minimise impacts on the local community, rehabilitation through trenchless relining was chosen in favour of sewer replacement.

As a result of the variety in sewer construction and shape, Melbourne Water said it anticipated that it will have to use more than one type of relining technology.

With the investigations and design phase to be completed between February and December of this year, construction is expected to start in March 2018 and be completed by March the following year.

The Williamstown Main Sewer Rehabilitation project is now underway, with stage 2 and 3 of the project beginning on 16 October; site investigations began in late-2016, and reinstatement is anticipated to be completed by mid-2018.
