Hope Valley Reservoir Reserve

Hope Valley Reservoir Reserve

The second reservoir built in Adelaide, Hope Valley was completed in 1873. The Reservoir receives water diverted by the Gorge Weir on the River Torrens via a tunnel (aqueduct) as well as the Mannum to Adelaide pipeline.

The two larger upstream reservoirs, Kangaroo Creek and Millbrook, are supply sources for Hope Valley.

Public access: Yes

What sets Hope Valley Reservoir apart

Capacity: 2.9 gigalitres (that would fill around 1,400 Olympic swimming pools]

Located in the heart of Adelaide’s north eastern suburbs, Hope Valley Reservoir was completed in 1873 to become Adelaide’s second reservoir, and is our oldest in operation.

Hope Valley is interesting because it does not collect surface water from the local catchment but is filled with water diverted by the Gorge Weir on the River Torrens via a tunnel supplied from Kangaroo Creek Reservoir. In fact, you’ll notice a channel surrounding the reservoir which catches and diverts local surface water away from the reservoir. This helps control the quality of the reservoir water before it is treated at the Hope Valley Water Treatment plant situated next to the reservoir.

Hope Valley Reservoir is our smallest reservoir and one of only two in the metropolitan area, the other being Happy Valley which is more than four times larger at 12.6 gigalitres.

Water Quality

Hope Valley Reservoir is one of 16 across the state that help supply water to more than 1.7 million South Australians. Water from the reservoir is cleaned and filtered at the Hope Valley Treatment Plant before being supplied to customers living in the north eastern suburbs. Treating drinking water before it’s supplied to people’s homes, businesses, schools, hospitals and more is important to make sure it is clean and safe to drink straight from the tap. You can learn how SA Water treats water and maintains the quality its customers value and rely upon.
