We are upgrading the existing 100 year old sewer that runs between Pasco Street, Williamstown and Scienceworks to ensure the Williamstown, Newport and Spotswood communities continue to receive a reliable sewerage service for years to come.

Keeping you informed

Project update - October 2018

Major works on the Williamstown Main Sewer Rehabilitation Project will continue throughout the month of October.

What to expect

Project team members will continue to visit each manhole multiple times to complete vital sewer and manhole rehabilitation works. These works involve:

  • Manhole rehabilitation works inside the manhole shaft, including lamination and liner connection works
  • Road reinstatement around manholes, includes Pasco Street, Dover Road and Douglas Parade

Working hours for October 2018 are day works only, Monday 7am through to Saturday 5pm. We will notify you of any works outside of these hours.

Activities planned for October 2018 include:

  • Multiple visits to each manhole along the 4.4 kilometre alignment.
  • Some odour when the manhole is first opened 
  • Some noise from the movement of trucks, machinery and reversing beepers.
  • Temporary changes to parking and traffic conditions. Please observe traffic management signage and traffic controllers at each location.
  • Lane and temporary road closures (including localised detours), as well as reduced speed limits near work areas.
  • Cycle lanes reduced in short sections – motorists are advised to be aware of cyclists on the road.
  • Pedestrian access around the works will be maintained at all times.

We will continue to keep local residents and businesses regularly informed about the works through letters, newsletters, door knocks and web updates.

What is happening

Inspections of the Williamstown main sewer revealed it is in poor condition and needs to be upgraded. The project is improving the condition of the sewer by rehabilitating the existing sewer pipe and associated manholes.

Works involve:

  • relining the existing 4.4 kilometre Williamstown main sewer using trenchless technology - now complete
  • rehabilitating the associated manholes along the alignment - near completion
  • reinstating affected areas as close as possible to pre-existing condition - commenced

The majority of the works will take place around the existing manhole locations.

Works started in  2017 and will take approximately 18 months to complete, weather permitting.

Where it is happening

The Williamstown main sewer runs under local streets between Pasco Street, Williamstown and Scienceworks in Spotswood. The map below shows the project alignment.

Project stages
Stage Estimated timing Description
Site investigations Complete ​Inspecting existing manholes and identifying existing underground and overhead services
Site mobilisation Complete ​Equipment and machinery will be delivered to the project area
Project construction activity Late 2018 Sewer relining, manhole modification and rehabilitation, and grouting works across the alignment. Multiple sites may be operational at once to allow works to be completed quickly and efficiently
Reinstatement Mid 2018 to late 2018 Restoring any areas affected by our works to their original or similar condition 

Impacts to the community

Like any major project, there are impacts associated with the sewer rehabilitation works. We are working closely with the local community to manage these impacts as much as practicable.

As majority of the manholes are located in residential streets you can expect some temporary changes to local traffic, parking and access conditions. A traffic management plan is prepared in consultation with Council to manage these impacts. We are also notifying residents and businesses in advance of the expected changes.

There is some noise and odour associated with the relining works. We are working closely with our appointed contractor to minimise these impacts, especially when working at night.

We do not anticipate any impacts to your water or sewerage services during the works.
