Bacchus Marsh Sewer Duplication

We are constructing a duplicate sewer main from Holts Lane, Darley to our outfall sewer south of Bacchus Marsh Road.

Project snapshot

Town(s): Bacchus Marsh, 

Status: Under construction

Cost: $3.4m

Expected Completion Date: June 2020


What does this project involve?

Western Water is constructing a new 2.5km sewer main that will transfer sewage from Holts Lane, Darley, to the sewer network south of Bacchus Marsh Road. The duplicate sewer is to be built near the existing sewer main, which was constructed in the 1960s and is nearing capacity.

Why is this project needed?

BM-Sewer-Alignment

The population of Bacchus Marsh and surrounding areas is growing fast. As such, the existing sewer network needs to be upgraded to ensure Western Water can meet the increased demand for essential sewer services. The existing sewer will continue to be used alongside the new sewer.

What sort of construction is involved?

Construction involves conventional ‘open cut’ trenching and boring beneath the roadway. A 375mm pipe will be laid from Bacchus Marsh Road to Masons Lane and connect into a new 300mm pipe from Masons Lane to Holts Lane that was constructed earlier in 2019.

Why was this construction alignment chosen?

The alignment was chosen as it’s mostly next to an existing sewer pipeline, which runs predominantly through agricultural land and away from built-up residential areas, thereby minimising impacts to residents during construction.

Will my services be affected by the works?

No, we don’t anticipate any interruption to sewer or water services.

What impacts can be expected during construction?

Traffic

Impacts will be kept to a minimum as construction is through mostly farming land. There may be minor traffic impacts as construction machinery will be operating close to the roadway. Traffic management will be in place, where required.

Noise and dust

There will be some construction noise and dust may be visible but this will vary at each work site.

Visual

You can expect to see some excavation work on the roadside. Fencing, barricades and trench covers may be used near the work site to ensure public safety.

What do we consider when planning a project?

There are several factors that inform 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, Land, Water and Planning, Landcare, Melbourne Water, Vicroads and Southern Rural Water.
