A long time ago I used to work part time for the local council. Part of my job was sewer inspection. We would put a camera on a pig down the line to asses the condition of the pipe. The Line had to be cleaned with a high pressure ware jet before hand. The guys that ran the jet pump collected a huge amount of change and jewelry over the months I was with them. They just had some one stationed at the point where the pipe entered the main sewer line and he picked out the goodies as they were washed out.
