Central Highlands Water is a regional water corporation providing high quality drinking water, sewerage, trade waste and recycled water services to customers in Ballarat and surrounding towns.

Formerly known as the Central Highlands Region Water Authority, it is one of 19 state-owned water businesses operating under the guidance of the Victorian Water Act.

Providing fully integrated catchment-to-tap-to-catchment water services, we collect, store, filter, disinfect and deliver water, and collect and treat wastewater.


We supply water and sewerage services for more than 130,000 people and trade waste and recycling water to large industries in the region.

Water Supply

Our core function is the collection, storage, treatment, transfer and distribution of water to the community within our service area. To do this we manage and protect the water supply system.

We also identify current and future water needs, educate the public about water, and develop programs for the conservation and efficient use of water.

Water Supply


Our sewerage system is managed and operated for the efficient transfer, treatment and disposal of sewage. Importantly, we identify the community’s sewerage needs and plan for its future needs.

We develop and implement programs for the recycling and reuse of treated wastewater, and investigate, promote and conduct research into the provision of sewerage services.

Trade Waste

Our trade waste management program partners with industrial and commercial customers and the community to provide environmentally friendly operating systems for the delivery, treatment and disposal of trade waste.

Trade Waste

Recycled Water

Our Class A recycled water:

  • reduces demand on our water catchments
  • helps us save a significant amount of drinking water
  • reduces the amount of wastewater discharged to regional waterways
  • provides a safe, alternative water source for gardening, irrigation of public parks, golf courses, car washing and Lake Wendouree.

Delivered to our customers via distinctive purple pipes, Class A recycled water is produced by Central Highlands Water at its North Ballarat Wastewater Treatment plant.

We perform these functions in an environmentally sound way, recognising the need to preserve landscape, fauna and flora.
