This job you are deals with human waste. I mainly clean equipment that is involved with the waste water treatment prossess. I shovel sludge (dried human waster and other stuff) out of drying beds into trailers to be taken to another place to be stored. I clean out storm water drains that contain a winters worth of mysteries of all sorts of hidden supprieses. We do testing of raw sewage right in our own labratory. All of this is done for a city of 20,000 people day after day by 3 differnet people 365 days a year. Mike if you would like to get dirty up in Vermont... Come visit me.
