A new pumping station will protect 1,500 homes and 500 businesses from flooding, while safeguarding aquatic life.
King's Lynn Internal Drainage board is building the biggest station in its 250-year history at Islington, near Lynn.
The £26m plant, which is being funded by the Environment Agency, will serve 25 square miles of the fens to the south west of the town.
Mel Neale, project manager for the drainage board, said it would house four powerful cannister pumps.
"When these pumps are running they are capable of moving 16,000 litres of water per second, capable of emptying an Olympic size swimming pool in just three minutes," she said.
