An Australian Newspaper has an article on "How it feels … to be a sewage diver" which is not to be confused with Dumpster Diving. The article has great quotes with a sense of humor that only the Aussies seem to have any more.
"I've done about 1000 hours of sewage diving. Working in a pit of sewage is very difficult; you can't see anything for a start, so everything's done by feel."
"You can walk through the sewage but not really swim. We've had times when there were big islands we've had to remove when pumps have broken down. We've had to go in with big suction heads and suck 500 foot of solid poo out — lovely days!
It doesn't smell bad at all for the diver; he's normally on processed air. The hardest job is the people who have to wash them down and clean them up afterwards."
"You might occasionally get a glove tear but that's really no difference to a piece of toilet paper ripping in the morning.It is a problem still though."
"People usually stand back a bit when they find out what we do — most of the time we can get a clear space at the bar."
And the best quote for last - "It doesn't really worry us, what we're diving in, but it would be nicer if people actually chewed their corn."
