Frankley Reservoir is a semi-circular reservoir for drinking water in Birmingham, England. Its construction was authorised by the Birmingham Corporation Water Act of 1892. It was built by Abram Kellett of Ealing in 1904.[1]

It contains 900,000m3 of water received from the Elan Valley Reservoirs,[2] 73 mi (117 km) away, in Wales, which arrives by the power of gravity alone, dropping 171 feet (52 metres) - an average gradient of 1 in 2,300.

Before 1987 it was leaking 540 litres per second. In that year Ground-penetrating radar was used successfully to isolate the leaks.[3]
