5 plastic barrels for garden use (Castlemorton Common WR13)

5 plastic home brew type barrels, guessing 20 or 25 litre capacity- have been in the garden with no lids on for years so not for human use !!! Taps look aged so probably not functional. Most have no lid. BUT handles are good and strong. May be useful for storing / transporting water ? Collection Castlemorton.
