The term "water reuse" is generally used interchangeably with terms such as wastewater reuse, water reclamation, and water recycling. A definition by the USEPA states: "Water reuse is the method of recycling treated wastewater for beneficial purposes, such as agricultural and landscape irrigation, industrial processes, toilet flushing, and groundwater replenishing (EPA, 2004)."
In Ancient Egypt, the rulers of the Twelfth Dynasty (c. 2000–1800 BC) undertook a far-sighted land reclamation scheme to increase agricultural output. They constructed levees and canals to connect the Faiyum with the Bahr Yussef waterway, diverting water that would have flowed into Lake Moeris and causing gradual evaporation around the lake's edges, creating new farmland from the reclaimed land.
The Bureau of Reclamation, formerly the United States Reclamation Service, is a federal agency under the U.S. Department of the Interior, which oversees water resource management, specifically as it applies to the oversight and operation of the diversion, delivery, and storage projects that it has built throughout the western United States for irrigation, water supply, and attendant ...
The Changi Water Reclamation Plant, the heart of the first phase of the DTSS, was opened by Prime Minister Lee Hsien Loong in June 2009. [63] The first phase of the DTSS consists of a 48-km long deep tunnel sewer that runs 20 to 55 metres below ground, and channels used water to the Changi Water Reclamation Plant at the Eastern end of the island.
This is important for agriculture. It is possible to desalinate saltwater, especially sea water, to produce water for human consumption or irrigation. The by-product of the desalination process is brine. [2] Many seagoing ships and submarines use desalination.
Among the largest of these water diversion projects is the Columbia Basin Project, which diverts water at the Grand Coulee Dam. The Bureau of Reclamation manages many of these water diversion projects. Some dams in the Pacific Northwest and California block passage for anadromous fish species such as Pacific Salmon and steelhead.
Many American reclamation districts were established prior to 1900 when local land owners first started working to put new land into agricultural production. Much of the lands "reclaimed" by 19th century reclamation districts were natural wetlands. Since wetlands are subject to flooding, these lands often were adjacent to sources of water ...
Mine reclamation – Restoration of land after mineral extraction; Land recycling – Reuse of abandoned buildings or sites; Soil salinity control – Controlling the problem of soil salinity; Watertable control – Use of drainage to control the groundwater level in an area; Land reclamation – Creating new land from oceans, seas, riverbeds ...
