Drain second jug (5)

I believe the answer is:

sewer

'drain' is the definition.
(sewer is a kind of drain)

'second jug' is the wordplay.
'second' becomes 's' (common abbreviation).
'jug' becomes 'ewer' (I've seen this before).
's'+'ewer'='SEWER'

(Other definitions for sewer that I've seen before include "Main drain" , "Drainage channel" , "Large pipe for carrying waste matter" , "dressmaker?" , "Plier of needle; drain" .)

I've seen this clue in The Telegraph.
