What about increased charges for running water? (9)
I believe the answer is:
euphrates
'running water?' is the definition.
(the river Euphrates)
'what about increased charges' is the wordplay.
'what' becomes 'eh' (I've seen this in other clues).
'about' indicates putting letters inside.
'increased' becomes 'up'.
'charges' becomes 'rates' (rate is a kind of charge**).
'eh' placed around 'up' is 'euph'.
'euph'+'rates'='EUPHRATES'
'for' is the link.
(Other definitions for euphrates that I've seen before include "Asian river" , "some running water in Middle East" , "River of Babylon" , "current in the Middle East?" , "running water in Iraq" .)
