@hippyjoe1955 The Amish porta potties are not cleaned by specialized service technicians using vacuum trucks to remove waste, followed by a thorough cleaning process. This involves disinfecting the entire interior with sanitizing spray, scrubbing surfaces (seat, tank, walls), pressure washing, and replenishing the holding tank with fresh water, blue deodorizer, and supplies.

Also, the Amish "porta potty" is made of wood and look weathered over the years.

Umm, I do not know where you live in the United States of America, but I live in the state of Ohio in Jackson County, and I have hundreds of friends that are Amish and been to their homes and farm steads. All of them are on county water and county sewer systems by county Law! A matter of fact speaking all county Health Departments in Ohio mandate by law the use of septic or county waste disposal. Ohio also has the largest Amish population than any other state in the Union. They use the same modern bathroom that hopefully you do, and they shower daily as well (Their hot water heater in their homes is wood fired but they have hot water). And yes, they pay for the county water and sewer bills like you and I do. I was lucky enough to buy a farm with well water and had to put in a new septic system in 2018 at the cost of $13,000, the Amish here would have the same expense for their septic system installs that I had that had to be approved by the county health department and inspected upon completion.

Now when I drove an Amish couple out to IOWA to see their family it was as you described, so do not say all when you speak and speak what you have certified knowledge about.

I'm not Amish, but I am in my own limited way, a history nerd.

That being said, I've studied the Amish and their anti-technological way of life as a way of gaining a historical perspective on some of the aspects of early pioneer living from the days of English colonization of the Americas in the early 1600's all the way up to the Western Movement of the mid-to-late 1870's.

Why is it anyone else's business where or what people use for a toilet so long as it is on their property and not posing a health risk to others?
