Bear tweets, finding sources of water! (10)

I believe the answer is:

standpipes

'sources of water' is the definition.
(type of pipe for water supply)

'bear tweets' is the wordplay.
'bear' becomes 'stand' (synonyms).
'tweets' becomes 'pipes' (both can mean birdsong).
'stand'+'pipes'='STANDPIPES'

'finding' acts as a link.

(Another definition for standpipes that I've seen is " They provide drink outside".)

I've seen this clue in The Telegraph.
