Melbourne Water is upgrading the Hawthorn Main Sewer (along the existing sewer alignment) and manholes for 1.7km on Burnley Street, Richmond to Power Street and Denham Street, Hawthorn.

The Hawthorn Main Sewer was originally constructed in 1901 and is at the end of its operational life. Relining the pipeline is now required to ensure the local community continues to receive a reliable sewerage service.

The project is expected to be completed by early 2020.

Project timeline

We began site investigations along the project alignment in January 2018.

Following these investigative works it will be determined what relining methodology is most suitable for these works. The map (below) shows the sewer maintenance holes and the full alignment that will be part of the relining project.

Once the work has been completed, the maintenance holes, shared path and roads will be reinstated.

Traffic parking cyclists and pedestrians:

There will be changes to traffic conditions including lane closures, potential road closures, parking restrictions and driveway access limitations.

These changes will be along:

  • Burnley Street
  • Church Street
  • Power Street
  • Denham Street

Further information will be provided once the methodology and construction plan has been confirmed.

The community will be informed when the sewer relining project is close to starting.

Stages of the sewer relining project

The staged approach follows a "spiral wound in place" methodology (see illustration below). This method has not been confirmed for Hawthorn Main Sewer relining.

Stage 1 - Cleaning of pipes and modifying the existing maintenance hole. The first stage of the project involves cleaning the sewer pipes and carefully measuring the existing pipes. The top of the existing maintenance holes will need to be widened to allow for sewer relining to take place.

Stage 2 -  Relining the sewer pipe. Stage two will involve relining the sewer using the selected methodology. This methodology is identified upon completion of the investigation phase.

Stage 3 - Upgrading the maintenance hole and reinstatement of the work area. The entries to the sewers will be upgraded with new ladders and new lids. The area surrounding the maintenance holes will be reinstated to existing conditions.

What will I notice?

Hours of work
The hours and stages of the project are yet to be determined. Once the investigation has been completed we will be able to confirm if night works are required. Night works are generally Sunday to Thursday from 9pm to 7am. Outside these hours quiet work may take place.

Night works need to take place when the sewage flows are at their lowest and there is less impact to traffic along Murphys st, Richmond and Denham st, Hawthorn.

Noise
Noise will be generated from moving vehicles, machinery and generators powering the equipment, during the hours of work. We will plan to reduce noise as much as possible for all night works.

Odour
Some odour is expected when carrying out the works. We will aim to minimise this as much as practicable.

Traffic, parking and pedestrians
There will be changes to traffic conditions including lane closures, potential road closures, parking restrictions and driveway access limitations. These changes will be along Creswick Street, Burnley Street, Church Street, Power Street, Bridge Road, Yarra Bank Reserve and Denham Street.

Further information will be provided once the methodology and construction plan is confirmed.

Minor detours may be in place for pedestrians. Please be careful around work areas and observe new signs. We will work with residents near the work areas to make sure access to private property is maintained at all times.

Respecting heritage and the environment
There is no vegetation removal expected. In some cases, we may need to undertake some trimming or alterations where trees are located in close proximity to the area of works. This may be required in Yarra Bank Reserve.

Sewerage and water services
We do not anticipate any impacts to your water or sewerage services during the works. Localised bypass pumping systems may be set up around some maintenance holes to ensure sewer services continue to operate.

Keeping you informed

We will notify local residents and businesses about these activities prior to starting works.

Doorknocks and letters will be used to inform residents, businesses and schools directly next to the work areas. We will also host a community information session closer to the construction start time. Signs will be used around our work areas to inform pedestrians, cyclists and drivers of changes to road conditions.

Community Information Sessions

The second Community Information Session about the relining project will take place on Wednesday 19 December at the south west corner of Power Street and Burwood Road Hawthorn, starting 10am finishing at 1pm.
