Anglian Water is preparing to renovate an Edwardian underground reservoir later this month in Ipswich, to bring it up to modern standards under a £1.5M project.
The resevoir will be drained on 19 September and 6,000t of topsoil will be removed from the roof. Then the tank, supports and pipework will be deep cleaned and inspected for any damage. Repairs will take place as necessary, and the removed topsoil will be replaced with a layer of stones on top of a new waterproof membrane.
“The reservoir is an amazing piece of construction,” said Anglian Water project manager Matt Humphrey. “We have had a look around inside using a remote camera but we can’t wait to actually get inside and have a look around for ourselves. Routine cleaning and maintenance has kept the reservoir in good condition since it was built, but the time has come to give it a more fundamental overhaul.”
The reservoir was built in 1902 and is buried beneath an earth embankment. The concrete tank is supported by rounded steel columns and has a capacity of 21M.l.
