It's been shut since late December
Work to repair the broken flume at the National Sports Centre will begin tomorrow.
The flumes were reopened in November last year - after three years - but weeks later were shut again after 11 people were injured exiting one of the slides.
In a statement, government says it's hopeful the work will be completed this week which would mean both slides can be fully functional.
The repairs will take place outside the centre’s opening hours, so all facilities, except the flumes, will remain open.
