That's the same here in England....people do not care about the workers that have to go down sewers and dig it out by hand.....Any type of oil or fat should never be tipped down your kitchen sine as it hardens in water and blocks pipes far taller than a man... Cotton buds and dental floss also cause huge problems......
People need to clean their own mess up and only then they will stop doing it :(
Last summer I had the septic tank suction truck come out to empty my septic tank. I know that no toilet paper was in the leech bed. So it musta all stayed in the tank, which is good.
In Greece most every where has septic tanks and people don't put paper down a toilet.....they all put it in bins and it taken to the dump... Fibre from Normal toilet paper blocks the porous Rock the septic tanks are dug in .....with out paper going down them it roughly eighty years before they need emptying......using paper that is reduced to every few years depending on the size of the tank and how many use it....
Sewer water is "cleaned" and filtered. The waste becomes a sludge that is disposed of. The "clean" water is re-introduced to our rivers and drinking water reservoirs. The water is not cleaned for hormones or other medicines.
It's slowly becoming more common for them to dispose of the sludge by using it as fertilizer. Which I can't help but think may be the reason for some hepatitis outbreaks from vegetables, such as the one from lettuce this year.
