When wastes became unpleasant because of odors and insects, people would simply move away from them. People were few and land was plentiful. As civilizations developed, man began to realize the need for sanitary disposal of human wastes. Ancient civilizations of the Old World have left ruins of wastewater disposal systems dating as far back as 4,000 B.C. Both the Greeks and the Romans built comprehensive wastewater systems, parts of which are still in operation today. With the fall of the Roman Empire, the civilization of European retrogressed into the "Dark Ages." In cities and villages, people disposed of excreta and household wastes by throwing them from the window or doorstep into the courtyard or street. It was during this period of history that Europe was swept by great epidemics of typhoid fever, cholera, dysentery, and other diseases. As the more astute members of society began to associate filth with disease, laws were passed pertaining to waste and refuse disposal. Thus, the environment in urban areas was greatly improved and the incidence of disease was diminished. In the United States, as long as we remained a country of small towns and farms, waste disposal was not a serious problem. But the country grew rapidly. As wastes began to pollute our inland waters, the quality of our water supplies was endangered. In 1855, our first wastewater systems were built in the cities of Boston and Chicago. Today, the vast majority of our organized communities have wastewater systems. With continued improvements in technology and stricter enforcement of antipollution legislation, the quality of our environment can be greatly improved. The Army also strives to protect the environment and soldiers from the spread of diseases by training its soldiers in the proper and safe way to dispose of waste. Liquid and solid wastes accumulate rapidly during a normal day. Under field conditions, this accumulation can readily become a breeding ground for insects and diseases. Since our fighting strength needs to remain healthy to protect, defend, and serve our country, waste disposal methods need to be effective, efficient, and safe. In this subcourse, you will be introduced to the fundamentals of wastewater disposal, suitable wastewater treatment systems at the installation and in the field, and ways to construct improvised wastewater disposal devices for field use. Our news and educational titles are privately compiled collections of official public domain U.S. government files and documents - they are not produced by the federal government. They are designed to provide a convenient user-friendly reference work and educational tool.
