I thought the Romans, or somebody like that, figured out how to deal with doo doo some time ago.
Yes, the Romans figured out how to implement waste water systems 2,000 years ago. The problem is that the Tijuanans literally give a million shi’ites a day.
Well, the Romans did install slit trenches to run the poo water into the ocean. But they made up for that bit of civility by running their drinking water thru lead pipes. When they went nutz from the lead they didn’t care about the air freshness? Then they quit calling themselves Romans and settled on Italians. And there’s still enough nutcases to go around.
Not the way wedeal with it today, with respect to sanitation and treating it.
