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 – February 2019

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

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 each manhole shaft, including UV lamination and liner connection works at the base of the sewer. Traffic management will be set-up around each manhole location when works are underway.
  • Quality assurance work across sections of the alignment to ensure the system is sealed and will service the community for decades to come.
  • Inspections at each manhole using CCTV technology, checking connection and lamination works.

Working hours for February are day works only, Monday 7am through to Saturday 5pm. We will notify local residents and businesses of any works outside of these hours.

Activities planned for February 2019 include:

  • Multiple visits to each manholes between Craig Street, Spotswood and Pasco Street, Williamstown.
  • Some odour when opening and accessing each manhole.
  • Some noise and possible vibration 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 via email, letters, newsletters, door knocks and web updates.

What is happening

Inspections of the Williamstown main sewer revealed it was in poor condition and needed 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 – 85% complete
  • reinstating affected areas as close as possible to pre-existing condition – near complete

Timings

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.
