Pitch tent while taking in river and towers (10)

I believe the answer is:

campaniles

'towers' is the definition.
(campanile is a kind of tower)

'pitch tent while taking in river' is the wordplay.
'pitch tent' becomes 'camp'.
'while' becomes 'as'.
'taking in' is an insertion indicator.
'river' becomes 'nile' (Nile is an example).
'as' enclosing 'nile' is 'aniles'.
'camp'+'aniles'='CAMPANILES'

'and' acts as a link.

I've seen this clue in The Telegraph.
