People mending pipes? (6)
I believe the answer is:
sewers
This might be a double definition.
'people' is the first definition.
(sewer is a kind of person)
'mending pipes?' is the second definition.
'sewers' can be an answer for 'pipes?' (sewer is a kind of pipe). I'm not sure about the 'mending' bit.
Can you help me to learn more?
(Other definitions for sewers that I've seen before include "Underground waste pipes" , "Conduits for waste matter" , "drains" .)
