Throughout the ages we have seen timeless inventions to numerous to name. We have seen everythingfrom the inventio of the radio to the engine to the atomic bomb. But there is one invention that goes onunappreciated, even looked down upon. The toilet. The toilet is an amazingly simple invention which,without it, the world would be a very different place. Without toilets there would be waste in our housesas well as in the streets that would have to be manually taken care of. Without the flush toilet there is nopossible way that the world could survive as populated as it is. It is an invention that has become, in ourtime, a necessity.
The Birth of the Flush Toilet
The first successful attempt at a true water flush toilet as see them today came as early as 1862. Known as a "washout", it consisted of a bowl with a hole in the bottom on the front or back. Below this was a p-trap filled with water in order to prevent gas escape.
Such wonderful devices became very popular over to the outhouses and earth closets (portable outhouses). They were much liked, though known to often flush incompletely.
An improvewment was made on the "washout" when the bowl was combined as one with the p-trap. This was known as a "washdown". Though it was an improvement, neither the washout nor the washdown were known for aconsistent complete flush.
Nearing the end of the centruy, sanitaryware manufacturers discovered that by diverting some of the water from tank pipe into the bowl acting almost like a jet flush. It was also learned that if the shape of the p-trap exit were changed it would act almost as a siphon sucking everything from the bowl.
Thus the modern flush toilet was born. Though people often credit Thomas Crapper for the invention of the flush toilet, he was in actuality only the owner of one of the first largest toilet manufacturers. It was in fact a collection of ideas of many people from Leonardo DaVinci to John Harrington to Alexander Cumming and on through history.
The Basic Concept Behind the Flushing Toilet
Flushing a toilet is the perfect example of basic physics. A toilet is little more than a storage tank of potential energy. The tank on the back of every toilet, as most people know, is filled with water.
When the flushing lever is pressed all of the stored water in the tank is suddenly released through a hole in the bottom of the tank.
The unique design of the Rectal Rocket allows the suppository to remain in place and release medication directly to the inflamed tissues without lapsing into the rectum. The contoured front end is inserted into the rectum to treat internal hemorrhoids, while the larger flared base remains on the outer surface of the anus to treat external hemorrhoids. The specialized vent allows the Rectal Rocket to stay in place by allowing flatulence to escape without expelling the suppository. This ensures the suppository is in constant contact with the affected tissues. Superior Comfort =
There have been many inventions throughout history and some of them have been a lot more helpful than others. The GPS, the Pacemaker, and the cell phone are all very important innovations made to the new world. Without these modern day inventions a lot of thing and the way we interact would be different
The Interaction Order of Public Bathrooms, written by Spencer E. Cahill, is an article that does a fairly well job at analyzing interpersonal relationships and individual practices in restrooms. Cahill used ideologies of Emile Durkheim, Erving Goffman, Margaret Atwood, Horace Miner, and Lyn Lofland to help construct his perspective on the individual’s expectations of bathroom etiquette through our experiences with others and how we internalize these behaviors.
When applicable, drums are used to store waste. As the accumulated drums are filled, they are moved to the storage area following the procedures in this document.

Amidst the school kids and the naked bum, there is a toilet. The free-standing, self-cleaning, public restroom installed by JCDecaux Company only costs a quarter. If you can stomach the sight of the remnants of human excrement and the pungent odor of fecal matter mixed with urine, stale cigarettes, and vomit, this toilet can prove to be extremely convenient. For those who drank too much Starbucks on their way to work or those with a crying four year-old, a public restroom amongst all the “customer only” signs seems like a reasonable solution. With a twenty minute limit, there is adequate time to relieve your bowels, seek shelter from the rain, shoot up ...
Sanitation was not top priority in ancient times. The latrines were placed in public areas allowing ten to twenty people at a time, with no privacy. Toilet
Before the 19th Century, sewage disposal was virtually unknown until the first American cities were built around the 1700’s. Human waste was originally disposed of in the woods, but some wealthy Virginians built large houses and used chamber pots to "do their business" indoors, and the contents would be thrown into the back yard. Later, as towns developed, waste was tossed into the streets to decompose or be washed away in the rainstorms (Virginia Places, 2010). Privies or outhouses were also built in back yards and were commonly used to dispose of waste. Toilets, also known as “water closets,” were put into homes in the mid 19th Century in the United States. The water closet had indoor plumbing where piping was run through the roof, and a gravity ...
Problems with sewage and garbage management as been in existence for as early as the 1970's as a result of the general concern expressed by people that worried about the increasing pollution in the human environment. But it even goes further then that. Ancient people have been finding ways of resolving sanitation. An ancient sewer system was found in the cities of Crete and Assyrian.

In many cases, you may find that issues with your septic tank backing up or becoming full quickly are not a result of the type of waste or other items that you are flushing down your drains.
My great grandmother was born on September 30, 1895 in Strum, Wisconsin, and used to tell us the most important invention for the home, in her lifetime, was the clothes washing machine. Now history always seems to make the present era seem more civilized, when in fact, it is probably only cleaner, thanks to my grandmother's favorite invention. But, I wonder if it is easier. Certainly, there were many patents issued in the 1880's for inventions that truly would change the lives of future generations, and a handful of these amazing contrivances would have a great impact on that which is truly important to an industrialized nation: the machinery that speeds business, business being the true backbone of a country, but to a country girl whose family depended on farming, the clothes washing machine still stands out as the one that saved her the most time.
Phase one in process of waste water treatment begins in the home, local businesses and community. Waste water from these buildings and surrounding areas travel through a pipe, or sewer which is sloped downward, and with the assistance of gravity, travels toward the waste water treatment plant. However, in larger communities or communities with unevenly leveled terrain, waste water cannot keep getting deeper to rely on gravity to transport the waste water and must pumped up by the assistance of a lift station so it may continue to travel to the water treatment plant. Once the waste water arrives at the waste water treatment plant, the first step is the removal of large debris such as diapers, underwear or other non-biological...

There is no doubt that the accomplishments made through technology are astonishing. Technology has made amazing impacts on everything from science in space to medical science to the devices we use every day that make our lives easier. People are living longer and better than ever before, but we can’t forget how to live without it. “Just because technology is there and makes something easier doesn’t mean we should rely on it so much that we can’t think for ourselves,” (Levinson).
