The free skip bin service offered by Hawkesbury City Council for flood affected residents will end at midnight on Sunday, July 25.
The free disposal service was provided in the wake of the March floods. The council arranged for more than 1600 skip bins to be delivered and collected.
The initiative was funded by the NSW Government through NSW Public Works.
The funding agreement ended on June 30 and council is now no longer able to take new orders for bins under the program after the cut off date mentioned above.
Hawkesbury Mayor, Councillor Patrick Conolly said that the service had been a success.
"Council is committed to supporting residents through the clean-up process. So far, 4,698 tonnes of flood waste have been collected," he said.
"We understand that people may still have flood waste requiring disposal. Our residents still have up until July 25 to use this service but after this date they will need to make other arrangements to dispose of this waste, which council has made available."
Cr Conolly said that kerbside collections were available for eligible residents to help with the disposal of waste. These can be arranged by calling 1300 889 527.
"While the skip bin service and free tipping of flood waste at our landfill is coming to an end, the Waste Levy Exemption for flood waste still applies for those residents that choose to dispose of their flood waste at the Hawkesbury City Waste Management Facility at 1 The Driftway, Londonderry," he said.
"This exemption is available until Thursday, September 30, 2021. Residents can further minimise their waste disposal costs by separating their load into recyclables and landfill."
