The Source of Adelaide’s Tap Water
Tap water in Adelaide comes from a sophisticated network that includes a variety of natural sources designed to ensure the residents of Adelaide have access to clean and safe drinking water.
TAP WATER IN ADELAIDE
Natural Reservoirs and Catchment Areas
The heart of Adelaide’s water supply beats in the Mount Lofty Ranges, where seven reservoirs play a pivotal role in collecting and storing water.
These reservoirs are the primary catchment areas, capturing rainfall, stream flow, and water transferred from the River Murray.
These reservoirs have a combined capacity to hold nearly 200 billion litres of water.
This volume is just shy of what metropolitan Adelaide uses in a year.
The largest of these, Mount Bold Reservoir, can store up to 46.5 billion litres, followed closely by South Para Reservoir with 44.4 billion litres.
Other key reservoirs include Myponga, Little Para, Kangaroo Creek, Millbrook, and Happy Valley, each contributing significantly to the region’s water supply.
Although smaller, the Barossa, Hope Valley, and Warren reservoirs are integral parts of this complex system.
Water from Mount Bold, for instance, is released as needed to maintain levels at the Clarendon Weir, eventually making its way to the Happy Valley water treatment plant and distributed across the metropolitan area.

The River Murray’s Contribution
The River Murray is another crucial source of surface water for Adelaide and numerous regional communities throughout South Australia.
It supports the water security of over 1.7 million customers by supplying water to 37 of the state’s 87 drinking water systems, including five of the seven water treatment plants that serve the metropolitan area.
The volume of water Adelaide draws from the River Murray can vary significantly yearly, influenced by natural reservoir inflow.
Water is conveyed through two significant pipelines to supplement the city’s reservoirs.
This reliance on the river has highlighted the need for additional water sources, especially during drought.
Adelaide’s Treatment Plants Ensuring Safe Drinking Water
Before tap water in Adelaide goes to households, it undergoes rigorous treatment.
These processes ensure that the water is safe to drink and meets the high standards set by government and health regulations.
All raw water in Adelaide is processed in one of seven water treatment plants dedicated to serving the metropolitan area.
These plants are strategically located to optimise the treatment of water drawn from a diverse range of sources.
- The Anstey Hill water treatment plant processes water from the River Murray and Millbrook Reservoir.
- Water from the Barossa Reservoir is treated at the Barossa water treatment plant, which also can integrate water from the River Murray, South Para, and Warren Reservoirs to meet demand.
- The Happy Valley water treatment plant treats water from its namesake reservoir, with the option to augment the supply with water from the River Murray and Mount Bold Reservoir.
- Hope Valley’s water treatment facility handles water from the Hope Valley Reservoir, supplemented by River Murray, Kangaroo Creek, and Mount Bold Reservoirs as needed.
- The Little Para water treatment plant treats water from the Little Para Reservoir, with provisions to incorporate water from the River Murray and Millbrook Reservoir to fulfil demand.
- Myponga’s water treatment plant, unique in its reliance solely on the Myponga Reservoir, does not draw water from the River Murray.
