The water play area at Millbrook Park has reopened.
The new facility was unveiled on Friday 17 June, just as temperatures in Jersey topped 33°C.
But it was shut one day later because of issues with the water quality.
The Infrastructure Department apologised, but said it had to put children's safety first.
Families can use it again from today (Wednesday 22 June).
