'meter reader found?' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'charge i had on running water' is the wordplay.
'charge' becomes 'tax' (tax is a kind of charge).
'i had' becomes 'i'd' (contraction).
'on' means one lot of letters go next to another (in a down clue, letters appear on others).
'running water' becomes 'river' (a river runs).
'tax'+'id'+'river'='TAXI-DRIVER'

Can you help me to learn more?
