Complete dump, according to reports (5)
I believe the answer is:
whole
'complete' is the definition.
(similar in meaning)
'dump according to reports' is the wordplay.
'dump' becomes 'hole' (hole can mean a dump or unpleasant place).
'according to reports' indicates a 'sounds like' (homophone) clue (I've seen 'according to report' mean this).
'hole' is a homophone of 'WHOLE'.
(Other definitions for whole that I've seen before include "Integral" , "undamaged" , "Complete, containing all the parts" , "Total" , "Entire, undivided" .)
