Marong is a town in Victoria, located 17 kilometres kilometres to the west of Bendigo. Its local government area is the City of Greater Bendigo.

The town is at the junction of the Calder Highway (A79) and the Calder Alternate Highway (A790). It has a population of around 900 people.


Water supply

The Bendigo water supply system part of the Coliban System (Northern) serves the towns of Bendigo, Marong and Axedale.

Raw water is sourced from the Sandhurst Reservoir located at Big Hill and holds up to 2,600 megalitres. This reservoir is filled from the Coliban Main Channel and the Eppalock-Bendigo Pipeline.

For further water resource information on the Coliban System (Northern) see our monthly Water Summaries.


Water treatment

Water is treated at the Bendigo Water Treatment Plant located at Sandhurst Reservoir.

The treatment process includes microfiltration, ozonation, BAC filtration, pH correction, fluoridation and chloramination.

Treated water is stored in the Sandhurst clearwater storage which has a capacity of 40 megalitres before it is piped to the reticulation system. Water is supplied to several interface points including four gravity supply points, storages in the Specimen Hill Reservoir, pumping to Edwards Road Tank and one pressure reduction point.

Where does my sewage go?

Wastewater from more than 39,000 customers in the Bendigo region is treated at the Bendigo Water Reclamation Plant in Epsom.

The majority of sewage in the region is collected in gravity sewers from areas including Kangaroo Flat, Golden Square, Spring Hill, Long Gully, Bendigo, Strathdale and White Hills, which flows via gravity to Epsom.

In areas located in valleys or at a lower altitude to the water reclamation plant sewage may need to be collected in pump stations and pumped into the Bendigo gravity network or direct to Epsom.

There are 17 sewer pump stations in the Bendigo system which service areas including Strathfieldsaye, Marong, Eaglehawk and Huntly.

The sewer system also collects wastewater from commercial sites in accordance with trade waste agreements and consents. These businesses range in size from cafes to large industries such as food processors and textile manufacturers.

What happens at the water reclamation plant?

The water reclamation plant is located at Howard Street, Epsom, adjacent to Bendigo Creek. It is the largest and most complex of our water reclamation plants. It treats around 20 megalitres per day to produce three different grades of reclaimed water: Class A, B and C.

The site also receives septic tank waste delivered by local septic contractors.

The heart of the Epsom water reclamation plant is the biological nutrient removal plant which removes nutrients, carbon and solids to produce Class C reclaimed water.

Class C is used as irrigation at the on-site farm and plantation, and supplied to nearby irrigators. The extensive 46-hectare lagoon system is used for treatment and to store excess winter flows for onsite irrigation during drier months. The lagoon system and May Swamp located on the northern most edge of the lagoon system is home to a vast range of birdlife.

Class B reclaimed water is produced by further treatment at the tertiary treatment plant using a combination of chemical dosing, filtration and UV disinfection. This water is supplied to the Fosterville gold mine and can be discharged to Bendigo Creek in accordance with the Environment Protection Authority (EPA) Victoria licence.

The Recycled Water Factory produces Class A water using a combination of chlorination/UV disinfection and membrane filtration.

Class A is the most highly treated and can be used for a wider range of uses. Customers include City of Greater Bendigo for its sporting facilities, parks and gardens; schools; rural, standpipes, commercial (for dust suppression, carwash and road works) and third-pipe customers in several housing developments.
Biosolids produced at Epsom are treated and then applied to land by farmers to derive the benefit from the associated nutrients.

The EPA Victoria licence specifies conditions for the management of emissions from the site including wastewater quality and odour. The beneficial reuse of wastewater and biosolids is conducted in accordance with guidelines approved by EPA Victoria, Department of Health and the Victorian Chief Veterinary Officer.


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.
