History Of Water Supply And Sanitation
The history of water supply and sanitation is one of a logistics, logistical challenge to provide Water supply, clean water and sanitation systems since the dawn of civilization. Where water resources, infrastructure or sanitation systems were insufficient, diseases spread and people fell sick or died prematurely. Major human settlements could initially develop only where fresh surface water was plentiful, such as near rivers or natural springs. 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. 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 dissipated. Early human habitations were often built next to water sources. Rivers would often serve as a crude form of natural sewage disposal. Over the millennia, technology has dramatically increased the ...

Qanat Kashan
A qanāt () or kārīz () is a water supply system that was developed in ancient Iran for the purpose of transporting usable water to the surface from an aquifer or a well through an underground aqueduct (water supply), aqueduct. Originating approximately 3,000 years ago, its function is essentially the same across the Middle East and North Africa, but it is known by a variety of regional names beyond today's Iran, including: kārēz in Afghanistan and Pakistan; foggāra in Algeria; khettāra in Morocco; falaj in Oman and the United Arab Emirates; and ʿuyūn in Saudi Arabia. In addition to those in Iran, the largest extant and functional qanats are located in Afghanistan, Algeria, China (i.e., the Turpan water system), Oman, and Pakistan. Proving crucial to water supply in areas with hot and dry climates, a qanat enables water to be transported over long distances by largely eliminating the risk of much of it evaporating on the journey. The system also has the advantage of being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skara Brae
Skara Brae is a stone-built Neolithic settlement, located on the Bay of Skaill in the parish of Sandwick, Orkney, Sandwick, on the west coast of Mainland, Orkney, Mainland, the largest island in the Orkney archipelago of Scotland. It consisted of ten clustered houses, made of flagstones, in earthen dams that provided support for the walls; the houses included stone hearths, beds, and cupboards. A primitive sewer system, with "toilets" and drains in each house, included water used to flush waste into a drain and out to the ocean. The site was occupied from roughly 3180 BC to around 2500 BC and is Europe's most complete Neolithic village. Skara Brae gained UNESCO World Heritage Site status as one of four sites making up "The Heart of Neolithic Orkney". Older than Stonehenge and the Great Pyramids of Giza, it has been called the "Scottish Pompeii" because of its excellent preservation. Care of the site is the responsibility of Historic Environment Scotland which works with par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Peru
The Andean civilizations were South American complex societies of many indigenous people. They stretched down the spine of the Andes for from southern Colombia, to Ecuador and Peru, including the deserts of coastal Peru, to north Chile and northwest Argentina. Archaeologists believe that Andean civilizations first developed on the narrow coastal plain of the Pacific Ocean. The Caral or Norte Chico civilization of coastal Peru is the oldest known civilization in the Americas, dating back to 3500 BCE. Andean civilizations are one of at least five civilizations in the world deemed by scholars to be "pristine." The concept of a "pristine" civilization refers to a civilization that has developed independently of external influences and is not a derivative of other civilizations. Despite the severe environmental challenges of high mountains and hyper-arid desert, the Andean civilizations domesticated a wide variety of crops, some of which, such as potatoes, peppers, peanuts, man ...

Fertilizer
A fertilizer or fertiliser is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment, or hand-tool methods. Historically, fertilization came from natural or organic sources: compost, animal manure, human manure, harvested minerals, crop rotations, and byproducts of human-nature industries (e.g. fish processing waste, or bloodmeal from animal slaughter). However, starting in the 19th cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irrigation
Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irrigation, is the olde ...

Waste Disposal
Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final Waste disposal, disposal. This includes the Waste collection, collection, transport, Sewage treatment, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related Waste management law, laws, technologies, and economic mechanisms. Waste can either be solid, liquid, or gaseous, gases and each type has different methods of disposal and management. Waste management deals with all types of waste, including industrial waste, industrial, chemical waste, chemical, Municipal solid waste, municipal, organic waste, organic, biomedical waste, biomedical, and radioactive wastes. In some cases, waste can pose a threat to human health. Health issues are associated with the entire process of waste management. Health issues can also arise indirectly or directly: directly through the handling of solid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minoan Civilization
The Minoan civilization was a Bronze Age culture which was centered on the island of Crete. Known for its monumental architecture and energetic art, it is often regarded as the first civilization in Europe. The ruins of the Minoan palaces at Knossos and Phaistos are popular tourist attractions. The Minoan civilization developed from the local Neolithic culture around 3100BC, with complex urban settlements beginning around 2000BC. After 1450BC, they came under the cultural and perhaps political domination of the mainland Mycenaean Greeks, forming a hybrid culture which lasted until around 1100BC. Minoan art included elaborately decorated pottery, seals, figurines, and colorful frescoes. Typical subjects include nature and ritual. Minoan art is often described as having a fantastical or ecstatic quality, with figures rendered in a manner suggesting motion. Little is known about the structure of Minoan society. Minoan art contains no unambiguous depiction of a monarch, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indus Valley
The Indus ( ) is a transboundary river of Asia and a trans- Himalayan river of South and Central Asia. The river rises in mountain springs northeast of Mount Kailash in the Western Tibet region of China, flows northwest through the disputed Kashmir region, first through the Indian-administered Ladakh, and then the Pakistani administered Gilgit Baltistan, Quote: "Kashmir, region of the northwestern Indian subcontinent. It is bounded by the Uygur Autonomous Region of Xinjiang to the northeast and the Tibet Autonomous Region to the east (both parts of China), by the Indian states of Himachal Pradesh and Punjab to the south, by Pakistan to the west, and by Afghanistan to the northwest. The northern and western portions are administered by Pakistan and comprise three areas: Azad Kashmir, Gilgit, and Baltistan, ...

Mesopotamia
Mesopotamia is a historical region of West Asia situated within the Tigris–Euphrates river system, in the northern part of the Fertile Crescent. Today, Mesopotamia is known as present-day Iraq and forms the eastern geographic boundary of the modern Middle East. Just beyond it lies southwestern Iran, where the region transitions into the Iranian plateau, Persian plateau, marking the shift from the Arab world to Iran. In the broader sense, the historical region of Mesopotamia also includes parts of present-day Iran (southwest), Turkey (southeast), Syria (northeast), and Kuwait. Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BC. It has been identified as having "inspired some of the most important developments in human history, including the invention of the wheel, the planting of the first cereal crops, the development of cursive script, mathematics, astronomy, and agriculture". It is recognised as the cradle of some of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Waste
Human waste (or human excreta) refers to the waste products of the human digestive system, Menstruation, menses, and human metabolism including urine and Human feces, feces. As part of a sanitation system that is in place, human waste is collected, transported, treated and disposed of or reused by one method or another, depending on the type of toilets, toilet being used, ability by the users to pay for services and other factors. Fecal sludge management is used to deal with fecal matter collected in on-site sanitation systems such as Pit latrine, pit latrines and septic tanks. The sanitation systems in place differ vastly around the world, with many people in Developing country, developing countries having to resort to open defecation where human waste is deposited in the environment, for lack of other options. Improvements in "Water supply, water, sanitation and hygiene" (WASH) around the world is a key public health issue within international development and is the focus of ...

Municipal Wastewater
Sewage (or domestic sewage, domestic wastewater, municipal wastewater) is a type of wastewater that is produced by a community of people. It is typically transported through a sewer system. Sewage consists of wastewater discharged from residences and from commercial, institutional and public facilities that exist in the locality. Text was copied from this source, which is available under a Creative Commons Attribution 4.0 International License Sub-types of sewage are greywater (from sinks, bathtubs, showers, dishwashers, and clothes washers) and blackwater (the water used to flush toilets, combined with the human waste that it flushes away). Sewage also contains soaps and detergents. Food waste may be present from dishwashing, and food quantities may be increased where garbage disposal units are used. In regions where toilet paper is used rather than bidets, that paper is also added to the sewage. Sewage contains macro-pollutants and micro-pollutants, and may also incorpora ...

Water Reuse
Water reclamation is the process of converting municipal wastewater or sewage and industrial wastewater into water that can be reused for a variety of purposes. It is also called wastewater reuse, water reuse or water recycling. There are many types of reuse. It is possible to reuse water in this way in cities or for irrigation in agriculture. Other types of reuse are environmental reuse, industrial reuse, and reuse for drinking water, whether planned or not. Reuse may include irrigation of gardens and agricultural fields or replenishing surface water and groundwater. This latter is also known as groundwater recharge. Reused water also serve various needs in residences such as toilet flushing, businesses, and industry. It is possible to treat wastewater to reach drinking water standards. Injecting reclaimed water into the water supply distribution system is known as direct potable reuse. Drinking reclaimed water is not typical.
