The fire at a former waste management facility in Maydown has been completely extinguished.
The fire, which started last Wednesday morning, burned for over a week and at its height saw 40 fire fighters battle the blaze.
The Northern Ireland Fire and Rescue Service (NIFRS) finished at the scene on Thursday afternoon.
“The fire has been fully extinguished and the smoke plume which had originated from the fire is no longer an issue to residents in the area,” said a NIFRS spokesperson.
“NIFRS would like to thank the members of the local community for their patience as fire fighters dealt with a large fire at waste management facility premises in the area.”
The spokesperson said the smooth running of the operation would not have been possible had it not been for the hard work of several other organisations.
“NIFRS would also like to thank all of the partner agencies for their involvement throughout this operation.
“NIFRS worked closely with the site owners, contractors, NI Environment Agency, Police Service of Northern Ireland, Public Health Agency, Northern Ireland Electricity and Derry City and Strabane District Council throughout the management of this incident.”
NIFRS had issued a warning to people living in the Strathfoyle area earlier in the week about the dangers of the smoke plume.
The cause of the fire is still under investigation at this stage.
