Sydney Water moves a lot of sewerage, and that movement depends on pumping stations like this one in Concord. I had a devil of a time getting it cleaned last time it was vandalised - I reported it online on 4 separate occasions, and each time, my report became lost in space - or perhaps clogged in the pipes. In the end, I had to write to the Managing Director, and she sorted it out quick smart. Something clogged in the IT channels by the sounds of things.
I'm working on the assumption that they have not gone back to their bad old ways, and my most recent report (number 090503-000027) will produce a quick result this time.
