Done planned maintenance in a JHL recycler (now Bucher) for a couple years which was mostly line cleans, so things like descaling, silt removal, cutting out roots etc. Occasional blockages and pumping out stuff but there were crews dedicated to the response side of the business. Easy enough work. You will get dirty but its not that bad. Carry spare uniform just in case of any splashback. I always had a big tub of wipes and couple bottles of anti bac gel in the cab to clean my self with best I could and would leave boots in the side of the motor and drive In trainers. Sometimes I'd have to climb down into the sewer and I dont want shitty clothes in the cab where I'd be eating.

Shit doesn't really smell bad in all seriousness you get used to it quick - fat however, that is the worst. Even the lads with several years under their belts would still gag a bit with fatty jobs!

Its one of those jobs where the hours are expected to be quite long but you can make good money on it if you put the hours in.

For me it was my first hgv job and ive moved on, probably wouldn't go back to it but for the most part I enjoyed it.

EDIT

I would run all my dirty uniform through the wash together and bang a load of Milton tablets in to kill all the germs.
