Around 19 people were injured in the accident when the Number 2 bus mounted a pavement on the quay during a busy shopping period.
One passenger was detained in hospital for a number of days, but has since been discharged. A number of passersby were also treated at the scene for shock.
It is likely that Bus Éireann will face a substantial compensation bill for personal injuries.
The State company yesterday refused to discuss the details of any likely payouts, but emphasised the fact that no one was seriously injured. The bus driver involved was treated for shock, but later released from hospital.
“All those injured were released on the same day, except for one,” spokesperson Cyril McIntyre said.
“Claims arise in the aftermath of an accident and that’s that,” he added.
The bus driver has now been interviewed as part of Bus Éireann’s internal inquiry into the crash. However, it remains unclear what exactly caused the bus, which had just pulled into the bus stop, to jolt forward onto the footpath.
“At this stage we don’t know what happened,” area manager Tim Daly said.
“It is in everyone’s interests to have the investigation carried out as soon as possible,” he added.
The Bus Éireann inquiry will look at the engineering and road safety aspects of the crash.
Gardaí are also progressing with their inquiry into the crash and have interviewed injured parties and witnesses.
“It is under active investigation and we await the report of the public service vehicle inspector,” Sgt John McDonald in Waterford said.
