Since speaking from personal experience being a turd herder for 6 years.
Worked for a City in the Sewer Dept.
Rich snobs poop smells just as bad as the poor folk's poop living on the other side of the tracks ! lol
Only difference the rich snobs poop has more fiber holding the poop together ...
Oh and just as many syringe needles !
Even just as much cat litter and egg shells we flushed out of the lines too.
Never understood why people put their egg shells in the sink and garbage disposal . They clog up lines , they don't disintegrate just stay that small size until they go through the Sewer plant and out to the drying beds then finally slowly dissolve would be a term to use ?..
