Could someone please put together a nice Sewer System pedia icon for me?

Something like this:
http://www.savebay.org/aboutus/bb_spring_02/jpegs/sewer_runoff.jpg
With a sewer pipe, preferably industrial age, i.e. brick, jutting out from side of an embankment with water pouring out into the river.

Thanks

Why not just copy the Aqueduct? I believe the graphics change into more of a pipe look in later eras.
