Trentham is a township nestled at the very top of the Great Dividing Range mid-way between Woodend and Daylesford, approximately 70 kilometres south of Bendigo.

The town is located between the Macedon Ranges and the Spa Country at the edge of the Wombat State Forest in the Hepburn Shire.

Trentham has a population of around 815 people.


Water supply

Raw water for the township of Trentham is sourced from groundwater and rainfall runoff into two reservoirs.

Trentham No.1 reservoir has a capacity of 26 megalitres and is filled from a spring and rainfall runoff, supplemented by water piped from a bore approximately 1 kilometre away. There is a bulk entitlement of 48ML for groundwater extraction from this bore.

Trentham No. 2 reservoir is gravity fed from springs and from the No. 1 reservoir and has a capacity of 52 megalitres.

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

Water treatment

Raw water for the township is treated at the Water Treatment Plant east of Trentham.

Water is treated by ultrafiltration, biological activated carbon filter and chlorination.

It is then stored in the clearwater storage tank at the plant from where it is delivered by gravity feed to Trentham's reticulation system.

The plant has the capacity to treat 0.7 megalitres per day. The clearwater tank holds up to 0.7 megalitres.

Where does my sewage go?

Wastewater from approximately 2,800 customers in Kyneton, Malmsbury, Trentham and Tylden is treated at the Kyneton Water Reclamation Plant, located north of Kyneton on the Kyneton-Redesdale Road.

The wastewater is collected via 13 pump stations and a sewer network comprising 80 kilometres gravity mains and 11 kilometres of rising mains.

The sewer system also collects wastewater from the Kyneton industrial estate including the Hardwicks abattoir and the livestock exchange.

What happens at the water reclamation plant?

The Kyneton Water Reclamation Plant consists of two systems.

Wastewater from the townships of Kyneton, Malmsbury, Trentham and Tylden is treated in the domestic wastewater treatment plant. The wastewater is treated through a series of processes that includes solids screening, biological nutrient removal, aeration, clarification, micro-screening and UV disinfection.

The Class B water produced is used to irrigate the Kyneton racecourse, sports grounds and botanic gardens as well as the extensive irrigation system on site at the water reclamation plant. In winter the majority of this water is stored in the on-site lagoons awaiting irrigation over summer or is discharged to the Campaspe River in accordance with the EPA licence. Sludge is stored in four lagoons.

Wastewater from the industrial estate along with septic tank waste delivered by local septic contractors is treated in a dedicated aerated lagoon/trickling filter system.

Sludge from the domestic and industrial treatment plants is periodically removed from the lagoons and the biosolids are beneficially reused for agricultural purposes.

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.
