The Hope Valley Reservoir is a 2.84-gigalitre (620-million-imperial- or 750-million-US-gallon) service reservoir in Hope Valley, South Australia, a suburb of Adelaide, South Australia.[1]

When completed in 1873 it was the second reservoir constructed in Adelaide; it is the oldest still in use in South Australia.[2] It covers 52 hectares (128 acres) and is retained behind a 950-metre (3,117 ft) long clay-cored earth wall. Water is transferred from the River Torrens via a tunnel and aqueduct. The river is also used to transfer water from the Kangaroo Creek and Millbrook reservoirs.[1]
