Greater Western Water has completed major water and sewer projects for Bacchus Marsh and surrounds, facilitating continue strong urban development. 

The $20 million works include an upgraded sewer pump station, a new sewer pipeline and two new water pipelines with most of the projects completed in the past month.  

Greater Western Water’s General Manager Growth and Infrastructure, Amanda Smith said with the local population projected to double to 46,000 in the next 20 years, this important investment will ensure we can meet demand for services from the Bacchus Marsh community for many years to come.  

“These are significant projects for the town’s sewerage and water network. In particular, it ensures Greater Western Water can meet the demand for sewerage services for at least the next 15 years,” Ms Smith said. 

“These projects have been safely delivered under COVIDSafe settings, demonstrating the concerted efforts of staff and contractors. 

“Greater Western Water thanks the community for their patience and understanding during construction.”  


Project details: 


Grant Street Sewer Pump Station Upgrade: 

A $6.7 million upgrade to the existing sewage pump station at Peelmans Lane near Grant Street. The project increases the pump’s capacity, enabling additional sewage to be received and pumped to the Bacchus Marsh Recycled Water Plant for treatment and recycling. The pump station upgrade also eases the load on the Avenue of Honour pump station, which receives most of the town’s sewage.  


Sewer Pipeline project: 

A new $9.2 million, 8 kilometre-long sewer pipeline from Peelmans Lane to the Bacchus Marsh Recycled Water Plant. The pipeline will help with the management of sewage flows throughout the town.  

 Bacchus Marsh Sewer Duplication:  

Work was completed late last year on a new 2.5-kilometre duplicate sewer pipeline from Holts Lane to the Avenue of Honour. The $3.4 million pipeline is critical new infrastructure to meet the increased demand for essential sewer services in the area. 


Water Pipeline projects: 

$1.74 million across two new water pipelines: a new 800-metre water main from Griffith Street to East Maddingley Road and a new 770-metre water main from Franklin Street west to Barry Street. These projects will boost water pressure  to businesses in the rapidly growing Parwan area.  


These are just several of the major projects we have under development and construction across our service area to deliver affordable, high quality service to growing communities like Bacchus Marsh.
