Country folk still have to think about it. Had to replace the 80 year old septic tank in the house I inherited, it was interesting to watch the new one put in, and even before construction they had to submit plan to local Health Dept. for approval. Still, many, many old houses are still using primitive methods. My aunt and uncle's drain simply led to the roadside ditch. (Cousin who inherited the house and farm put in a septic tank). A friend of mine finally had to replace her "system" which was simply two big steel barrels underground, punched full of holes, filled with large rocks. The old systems were "grandfathered" in with the then new sanitation laws, so many still exist and are in use. Ugh.

Yeah, probably slaves. 😖 I wish Hank had mentioned that the public Roman bathrooms weren't very sanitary, either. There was usually only a limited number of tersoriums (natural sponge attached to a stick) for wiping- which was shared by all comers. It was simply rinsed in between users either in plain water (running through the pipes), or in a bucket of vinegar or salt water. 🤢

Same thing goes for floor drains and sinks that don't see a lot of use. And floor drains can evaporate even faster due to having no lid to slow it down, but still being a large diameter pipe. A little bit of cooking oil slowly down the drain can significantly slow the evaporation in infrequently used water drains. :)

As somebody who does content on Mesoamerican history, I wanna clarify some stuff about Palenque's toilets and talk about other Mesoamerican sites that had them. Firstly, i've looked into Palenque's waterworks systems before, it should be noted that while there are what appears to be toilets at Palenque, as far as i'm aware there's no evidence that those toilets themselves were part of the pressurized channel that was found at the site, which from the papers I've read seems to have been in place to create a upwards fountain/spout, though maybe i'm unaware of newer research. I will say Palenque in general had very complex waterworks systems,, the site had dozens of springs in or around the city which coalesced into many streams and rivers which ran through it, so the city had dozens of open air and underground aqueducts, drainage systems, dams, reservoirs, etc to deal with that. As far as other other Mesoamerican cities with toilets, Teotihuacan seems to have had some: Teotihuacan was a major Metropolis in Central Mexico during the Classical period, and at it's height around 500AD, had 100,000+ denizens, had a planned urban grid covering almost 2 dozen square kilometers of fancy temples and palaces with painted frescos, dozens of rooms and open air courtyards, which even most of the city's commoners lived in. Some these palace compounds had plumbing and channel systems, and what seem to pretty clearly resemble toilets, though in conversations I've had with researchers who have worked at the site, excavations haven't yielded connections to other plumbing systems in the city, which is odd since in photos of the toilets there are what appear to be channels attached to them. It's also known that the Aztec captial of Tenochtitlan had public latrines/toilets alongside major roads, and that there civil servants who washed and swept streets and buildings and collected waste from these toilets (allegedly on a daily basis), and that waste was then recycled into dyes and fertilizer.

Under Elizabeth I in England she had a great Chancellor, who was then also her bookkeeper and he kept meticulous records. People who would clean sewage off the streets of London were well paid, but there were never enough. Street cleaners could then sell the sewage to farmers, just bonus income. This was the original London, now often referred to as "the City", very small in comparison to modern London. I'm surprised he didn't mention London's huge sewer system, installed under Queen Victoria. It was and is a *phenomena*, most of it still is use as built. However, originally it just dumped into the Thames River far downstream. Now, modern sewage treatment plants are in place. ... Before its dumped into the Thames. There were still problems. Prince Albert her Consort, reportedly died of typhoid (which modern scholars are rather dubious about but [shrug]) from old leaky pipes under the Palace.

Below was the open air and sea rocks. You do your business, and it was taken out with the tide. Not such a big deal in smaller communities, but would cause a major pollution problem in larger cities for sure. I have fond memories of being outside playing, and running in the stage to go to the washroom...You could feel the cool sea air against your butt lol

"some arid places have a nr1 and nr2 button" mate.. i've been over half of Europe. I only ever NOT see it in houses owned by the retired folks. "why waste 10% of our water bill when this one cheap button can save it?" seems like a no-brainer for most western people it seems. >.>

@jblyon2 2 года назад

Water here is cheap compared to most of Europe. I pay less than $15/month where I live, and it's an expensive area. People only really start caring because once the sewage treatment plants for your area get upgraded to modern standards the sewage bills roughly triple. Since sewage bills are based on water usage people suddenly start caring. Also, a lot of people in rural areas have plentiful well water and septic systems, so they don't really care how much water gets used. Plus any excess usage just filters back into the ground from the septic system. My parents have no reason to care that their old toilets use 3.5 gallons/flush. It comes out of the ground in the back yard, gets treated naturally by bacteria in the septic system, and seeps back into the ground in the front yard.

There are interesting ancient toilets in Tintagel (Devon, UK). People apparently socialised in an open room, pooping and chatting. The poop fell straight into the ocean, next to "Merlin's Cave". The same method, but with privacy, was used in a high Alpine hut not long ago, where my poop dropped onto the glacier below. It'll remain deep frozen for about another 100 years.

@@Allan_son No we don't suck that much out of aquifers. 90% of our water does come from the river (by way of the lake/reservoir). We do suck some out of the ground, if we don't, it will come up naturally, sometimes in casino basements. We actually "store" water underground and rely almost exclusively on the river. 90% to be exact. As for waste, I'm sure there's a lot by the casinos and hotels. Not to mention the rich people here. We had a recent listing of the top 150 water users, mostly rich hotel owners, boxers, musicians such as the Fiver Finger Death Punch singer, etc. The rich may waste water, but the poor do not.

@SadisticSenpai61 2 года назад

"reinvent the toilet" - shows some ridiculously high tech toilet with a ton of moving parts and definitely requires electricity. Um, I'm gonna pass on that. One of the best things about our toilet system? It doesn't require electricity (at least not in individual houses). Why do I say that's a major bonus? I live in Tornado Alley, the power lines aren't buried pretty much anywhere here, and we also lost electricity for a week last summer when the derecho came through Iowa (where we live). If we had had to leave the house every time we needed to use the toilet? We literally couldn't have stayed in our house that week. Yes, it was hot. Yes, it was annoying. Yes, we played board games and read by candlelight. Yes, we lost all the food in our fridge and freezer. Yes, we couldn't cook anything because our stove/oven is electric. But we were able to sleep in our own beds every night and we didn't have to worry that we wouldn't be able to use the toilet - they restored the power to the water treatment plant before they did anything else. Notably, the businesses on S Duff got their power back that night, but the hospital complex had to wait about a day and a half. Priorities, amirite? Goodness knows, it would have been an emergency if Walmart didn't have power! The hospital? Eh, they can wait.

@veramae4098 2 года назад

Modern hospitals all have major electrical backup systems that come on instantly even if power only goes off for a few seconds. Batteries and propane electrical generators. Installations differ only in how long they can provide power, minimum is 24 hours. The lights in the surgical theatre would flicker, and then be steady again. Your local hospital was almost certainly never without electricity. P.S. Before throwing shade in the Internet you might want to check your facts first. Retired librarian, MI / US P.P.S. I went back to look at your post, hoping to find a city name to check on your local hospital's power supply before posting, but you hadn't included that.

@SadisticSenpai61 2 года назад

@@veramae4098 96 hrs per their emergency response PDF. Still, it seems bizarre to wait to restore power to the area (which includes a lot of medical and treatment clinics). It should have been higher up in the priorities. We were at the medical complex when the derecho hit for some appointments - the last appointment was cancelled and rescheduled for the next day over the phone (which is how we know the power wasn't restored at the clinic - Dr told us over the phone). When we found out the appointment was cancelled, we tried to call for our on-call pickup, but it turns out the phone system HIRTA uses requires electricity. Fortunately for us, a HIRTA driver arrived for another patient a little bit later. The person he was there to pick up was stuck in the basement - the guy used a power chair and needed the elevator. He'd been in the basement for 2 hours at that point. The chair was too heavy for them to carry up the stairs so they literally couldn't get it out of the basement without the elevator. The hospital itself was likely fine, but the clinics are all McFarland. They didn't have the backups.

@jblyon2 2 года назад

Until they get upgraded to modern standards the treatment plants in areas with combined storm drains and sewers regularly have to release untreated waste water when it rains. Once they're upgraded to handle the flow during heavy rains your sewage bill will roughly triple too! The systems should definitely be separate in most areas, though having combined ones in areas where rain is rare is important because the rainwater entering the storm drains tends to be badly contaminated.

Thanks for the great video! A hint. When entering a house that has been uninhabited for some time, the smell is often pungent. The time without use dries up the hydraulic seal of the siphons, or "S" pipes and the stench of sewage returns to the rooms. Open all the faucets and showers, let the water run for a minute, flush all toilettes and ventilate the place well. The stench will disappear immediatelly.
