The first known wastewater management system is located in present day Syria . Located in the Fertile Crescent, the Mesopotamian "oasis" shows evidence of wastewater management beginning around 6500 BCE. The area is about 120 km northeast of the ancient city of Palmyra. [1]
Throughout history, people have devised systems to make getting water into their communities and households and disposing of (and later also treating) wastewater more convenient. [1] The historical focus of sewage treatment was on the conveyance of raw sewage to a natural body of water, e.g. a river or ocean, where it would be diluted and ...
Throughout history people have devised systems to get water into their communities and households, and to dispose (and later also treat) wastewater. [67] The focus of sewage treatment at that time was on conveying raw sewage to a natural body of water, e.g. a river or ocean , where it would be diluted and dissipated.
An example of a wastewater treatment system. Sanitary engineering, also known as public health engineering or wastewater engineering, is the application of engineering methods to improve sanitation of human communities, primarily by providing the removal and disposal of human waste, and in addition to the supply of safe potable water.
The facility treats 110 million U.S. gallons (420 megaliters) of wastewater per day, with a capacity of up to 167 million U.S. gal/d (630 ML/d), making it the largest tertiary treatment plant in the western United States. It serves 1.5 million residents and over 17,000 business facilities in eight cities.
Sanitary sewers are sized to carry the amount of sewage generated by the collection area. These sewers are much smaller than combined sewers , which are designed to also carry surface runoff . A sanitary sewer is an underground pipe or tunnel system for transporting sewage from houses and commercial buildings (but not stormwater ) to a sewage ...
For example, the Netherlands have 99% of the population connected to the system, and 1% has an individual sewage disposal system or treatment system, e.g., septic tank. Others have slightly lower (although still substantial) percentages; e.g., 96% for Germany .
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges.
