A number of staff have been suspended as police investigations into the claims continue.
The abuse is alleged to have occurred at Ralph's Close, a new residential unit based at the city's main mental health care hospital.
It became operational just two years ago and provides accommodation for up to 16 adults with a learning disability.
In recent days, the Western Health Trust received a number of allegations suggesting a resident or residents had been mistreated.
However, senior management won't specify the nature of the alleged abuse.
Aidan Gordon, of the Western Trust, told UTV they are trying "to make sure that everybody knows that if anybody has any information which could contribute to that investigation, we would really welcome them to come forward."
He said that some members of staff have been suspended as "a precautionary measure" while enquiries continue.
"We have managed to replace those staff," he said.
"We have brought some staff in from external facilities and we have bolstered the management cohort within Ralph's Close to try and reassure the families of current residents that the Trust is taking all the steps that are required ensure the residents are safe."
Assembly members have been meeting Trust management.
Mark H Durkan, SDLP MLA for the area, say this be a difficult investigation for the authorities.
"I sincerely hope - and I'm sure the wider Derry community - hopes that these allegations prove to be untrue.
"But it's vitally important that anyone who can assist the police with their investigation and the Trust with theirs should come forward at this stage."
The Western Trust says wants anyone with information to contact them on 028 7161 1366.
