Children's cancer wards closed more than three years ago amid concerns about the water system will reopen next week following an £8.9 million upgrade.
Youngsters in wards 2A/2B at the Royal Hospital for Children (RHC) in Glasgow were moved to wards in the adult Queen Elizabeth University Hospital (QEUH) in September 2018 to allow for further investigations after the concerns emerged.
The Scottish Hospitals Inquiry is currently investigating the construction of the QEUH campus, which includes the children's hospital, after issues at the flagship site were linked to the deaths of two children.
