The clean up of 4000 properties along the River Murray is under way with more than 1000 tonnes of refuse already collected from kerbsides in river communities.
The state and federal government have been working together to provide hardship and accommodation grants for impacted residents in one of the most significant natural disasters in SA's history.
Federal Emergency Management Minister Murray Watt said support would be ongoing.
"The recovery and rebuilding effort is well underway, but we know that it takes time for communities to get back to normal," he said.
"It's not too late for people to apply for assistance, and I'd encourage people to visit the Services Australia and SA government website to see what's available."
During the emergency, more than 4000 calls were made to relief and recovery hotlines, with nearly 1700 registrations for clean up assistance and 935 free waste disposal vouchers issued, resulting in 1167.45t of waste collected so far.
Of this, about one-third was able to be recycled or reused, with the rest sent to landfill.
A lead agency in Green Industries SA was selected to coordinate the urgent immediate clean-up activity, using local contractors.
Major work will now begin under the primary contractor Disaster Management Australia, a subsidiary of the John Lyng Group, which has led similar flood clean ups in Queensland, NSW and Victoria.
This will see DMA expand the clean-up activity and conduct structural assessments and hazardous waste removal, including the safe removal of asbestos at no cost to property owners.
State Climate, Environment and Water Minister Susan Close says with local suppliers and tradespeople, and the expertise of a nationally recognised leader in disaster waste recovery, residents and businesses along the River Murray can expect to see a lot of activity in the coming weeks.
"Since roads became more accessible, local crews have removed more than 1000 tonnes of waste up and down the River," she said.
"This includes sand from sandbags to be reused in the rebuilding and repair of the region, and scrap metal that will be reprocessed at an Adelaide facility."

The option for demolition for properties too severely impacted for repair will also be offered at no cost to property owners.
Property owners registered with GISA will be contacted directly by a representative from DMA about the next steps for their situation and assigned a case manager to work through the process of assessment, removal and make safe activities.
