Grant Street Sewer Pump Station and Sewer Main - Maddingly to Parwan

We’re upgrading our sewer pump station in Peelmans Lane Reserve and building a sewer rising main from Maddingley to Parwan to improve and expand the area’s sewerage system.

Project snapshot

Town(s): Maddingley, Parwan, 

Status: Planning

Cost: $12 million approximately

Expected Completion Date: 2018


What does this project involve?

We’re upgrading the existing sewer pump station in the reserve at the corner of Grant Street and Peelmans Lane.

This involves deep excavation to install pumps into an underground structure, and an electrical fit out which includes an above ground electrical cabinet.

We’ll also construct an 8 km sewer rising main alongside Grant Street, Parwan Road, Geelong-Bacchus Marsh, Exford Road and Parwan Road South.

Once complete, the pump station will receive sewage from the existing sewerage network and pump it via the new sewer main to the Bacchus Marsh Recycled Water Plant in Parwan for treatment.

Why is this project needed?

Bacchus Marsh’s population is predicted to increase to more than 28,000 by 2021. With rapid development already taking place in Maddingley West, the existing sewerage network will eventually lack the capacity to cope – new sewer infrastructure is essential.

Building a new pump station and sewer main will ensure we’re able to keep pace with the town’s growing population; comply with all government legislation and standards; and continue to supply quality sewerage and recycled water services to our customers.

What will pre-construction works involve?

To ensure the safety of people working on the sewer pump station, we need Powercor to relocate overhead power lines. For Powercor staff to do this, we have removed one non-native tree and pruned other trees in Peelmans Lane Reserve. Our arborist worked in accordance with Powercor’s requirements for clearances.

When will the power lines be upgraded in Peelmans Lane Reserve?

Powercor is will be realigning the overhead power lines in March 2017. Residents will be notified before work starts.

What will be visible at the pump station site once the project is complete?

As the pump station will be installed underground, the only additional noticeable infrastructure will be an above ground electrical cabinet. Western Water will work to ensure the visible infrastructure is safe and suits the aesthetics of the reserve.

What factors do we considering when planning a project?

There are several factors that affect our project planning. These include environmental and geotechnical impacts, cultural heritage, specialist investigations (such as a biodiversity assessment), population forecasts, location of other underground services (e.g. electricity, phone/internet, gas lines) and accessibility.

Consideration of future infrastructure in the area, such as major roads and drainage scheme infrastructure is pivotal to our planning along with advice from key stakeholders such as:

  • Moorabool Shire Council
  • Department of Environment
  • Department of Environment, Land, Water and Planning
  • Landcare
  • Melbourne Water
  • Vic Roads
  • VicTrack
  • Southern Rural Water

Will my services be affected by the sewer main works?

No, we don’t anticipate any interruption to your water supply or sewerage service. Due to the size and high pressure of the new sewer main, property connections will not be possible.

What impacts can I expect during the works?

Western Water will keep construction impacts to a minimum; however the following are likely to occur:

Traffic

We expect impacts on traffic to be minimal, however, on some occasions our team will need to undertake work very close to the roadway. For your safety, and that of our team, traffic management will be in place if required − we ask for your understanding at these times.

You may also notice increased traffic along the road as our contractor goes about their work.

Noise and dust

At times, you will hear construction noise and see dust coming from our site. This will not last long as our contractor will continue to move along the sewer main alignment throughout the project.

Visual

You can expect to see some excavation work on the roadside. Fencing, barricades and trench covers may be used near the worksite to ensure your safety. Our contractor may also establish a storage area nearby for equipment and construction materials.

Will my driveway be affected by the sewer main works?

We may need to briefly work across some driveways. If this is the case, you will be notified in advance by our contractor so that alternative access arrangements can be made. Your driveway will be reinstated to its original condition once works are complete.

How will I be kept informed?

We’ll keep you updated through:

  • in person (information sessions, door knocks, home visits, community presentations)
  • printed materials (letters, project updates, local newspaper articles, advertisements)
  • online (website updates, social media posts)

How long will the project take?

Western Water is in the planning stage of this project. Below is an approximate timeline for the project.

  • Early 2017 - Tree works and power line upgrade
  • April 2017 - Design completion
  • April 2017 - Tender advertised
  • May 2017 - Tender awarded
  • July 2017- Mid-year 2018 - Construction
