Gunbower is located approximately 90 kilometres north of Bendigo in the Campaspe Shire local government area.

Situated on Gunbower Creek, the town has a population of around 500 people.

Gunbower Island is formed between the Murray River on the north side and the Gunbower Creek to the south. 


Water supply

The water supply system serves a population of residential, commercial and industrial customers with around 175 connections.

Gunbower is part of the Murray System with a direct offtake from Taylor Creek.

Water for Gunbower is pumped from Taylor Creek into a membrane filtration plant and into water storages at the water treatment plant.

For further water resource information on the Murray System see our monthly Water Summaries.


Water treatment

The Gunbower Water Treatment Plant was built in 1994.

Work commenced on a major upgrade to the plant in July 2011 at a cost of $4.1 million and finished in May 2012.

The works have improved water reliability, treatment and broader operational flexibility, and have also rectified a number of occupational health and safety concerns.

The new treatment system at Gunbower allows us to better handle the variability in the raw water supply that is experienced throughout the year.

Water is treated by MIEX (magnetic ion exchange) to remove dissolve organic matter, flocculation, clarification, membrane filtration, UV disinfection and chlorination.

Treated water is stored in a 136 kilolitre elevated tank before it is gravity fed into the Gunbower reticulation system. Water is also transferred downstream of the urban water supply system to supply by agreement customers in the Gunbower Rural Water Supply Scheme.

Where does my sewage go?

Wastewater from Leitchville and Gunbower is treated at the Gunbower/Leitchville Water Reclamation Plant located approximately four kilometres south of Gunbower.


What happens at the water reclamation plant?


Wastewater is treated at the plant through a lagoon system to a Class C standard. The system consists of two facultative lagoons, a maturation lagoon and winter storage lagoon and an irrigation system.

The Class C reclaimed water is evaporated or irrigated to farmland surrounding the site.

The facility currently treats around 40 megalitres annually.

The Environment Protection Authority (EPA) Victoria licence specifies conditions for the management of emissions from the site including wastewater quality and odour.


Water restrictions

Permanent Water Saving Rules (PWSR) apply.

PWSR are a set of five common sense water rules that are in place at all times when water restrictions are not in force.
