The maximum depth of water was approximately 7 m when full. Clean water entered the 10.8 m deep octagonal inlet well via a tunnel where it was stored. Water was then pumped down several pipes to Derby, Leicester, Nottingham and Sheffield from a 10.8 m deep hexagonal gauge well. In case of over filling, the reservoir was constructed with two giant overflow pipes.
