Water Management In Greater Mexico City
Greater Mexico City (''Zona Metropolitana del Valle de México''), a metropolitan area with more than 19 million inhabitants including Mexico's capital (''Ciudad de México'', or CDMX) with about 9 million inhabitants, faces tremendous water challenges. These include groundwater overexploitation, land subsidence, the risk of major flooding, the impacts of increasing urbanization, poor water quality, inefficient water use, a low share of wastewater treatment, health concerns about the reuse of wastewater in agriculture, and limited cost recovery. Overcoming these challenges is complicated by fragmented responsibilities for water management in Greater Mexico City: * The Federal government is in charge of regulating the use of water resources, contributing to the financing of investments and supplying bulk water from other basins through the National Water Commission Conagua; * The State of Mexico provides bulk water, treats wastewater and assists municipalities in providing water and ...

Greater Mexico City
Greater Mexico City refers to the conurbation around Mexico City, officially called Metropolitan Area of the Valley of Mexico ( es, Zona metropolitana del Valle de México). It encompasses Mexico City itself and 60 adjacent municipalities of the State of Mexico and Hidalgo. Mexico City's metropolitan area is the economic, political, and cultural hub of Mexico. In recent years it has reduced its relative importance in domestic manufacturing, but has kept its dominant role in the country’s economy thanks to an expansion of its tertiary activities. The area is also one of the powerhouse regions of Latin America, generating approximately $200 billion in GDP growth or 10 percent of the regional total. , 21,804,515 people lived in Greater Mexico City, making it the largest metropolitan area in North America. Covering an area of , it is surrounded by thin strips of highlands separating it from other adjacent metropolitan areas, together with which it makes up the Mexico City megalopo ...

Lake Texcoco
Lake Texcoco ( es, Lago de Texcoco) was a natural lake within the "Anahuac" or Valley of Mexico. Lake Texcoco is best known as where the Aztecs built the city of Tenochtitlan, which was located on an island within the lake. After the Spanish conquest of the Aztec Empire, efforts to control flooding by the Spanish led to most of the lake being drained. The entire lake basin is now almost completely occupied by Mexico City, the capital of the present-day nation of Mexico. Drainage of the lake has led to serious ecological and human consequences: the local climate and water availability have changed considerably, contributing to water scarcity in the area; subsequent groundwater extraction leads to land subsidence under much of the city; and native species endemic to the lake region have become severely endangered or extinct due to ecosystem change, such as the axolotl. After the cancellation of the Mexico City Texcoco Airport, the government initiated a major restoration project ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tequixquiac
Tequixquiac is a municipality located in the Zumpango Region of the State of Mexico in Mexico. The municipality is located north of Mexico City within the valley that connects the Valley of Mexico with the Mezquital Valley. The name comes from Nahuatl and means "place of tequesquite waters". The municipal seat is the town of Santiago Tequixquiac, although both the town and municipality are commonly referred to as simply "Tequixquiac". The municipality is known as the "cradle of prehistoric art in the Americas" because of the sacrum bone and other artifacts found in the region. History The sacrum bone found in Tequixquiac is considered a work of prehistoric art. The first indigenous settlers of Tequixquiac were the Aztecs and Otomi, who settled permanently due to the abundance of rivers and springs. They were engaged mainly in agriculture and the breeding of domestic animals. In 1152, the Aztecs, on their way from Tula-Xicocotitlan to Tequixquiac and the Valley of Mexico, d ...

Mezquital Valley
The Mezquital Valley ( ote, B’ot’ähi) is a series of small valleys and flat areas located in Central Mexico, about north of Mexico City, located in the western part of the state of Hidalgo. It is part of the Trans-Mexican Volcanic Belt, with altitudes between and above sea level. It is one of Mexico's main semi-arid/area regions, whose native vegetation is dominated by cactus species, mesquite trees, and maguey with pine and oak trees in the highest elevations. It is considered to be part of the northern extension of Mesoamerica, with one major archeological site, Tula, which was the main city of the Toltecs, an important influence for the later Aztecs. However, from the Aztec period to the 20th century, it was sparsely populated and very poor, with one main indigenous ethnicity, the Otomis. In the 20th century, irrigation works were created to take advantage of the water in the Tula River, along with wastewater drained from the Valley of Mexico for agriculture. Today the ...

Combined Sewer
A combined sewer is a type of gravity sewer with a system of pipes, tunnels, pump stations etc. to transport sewage and urban runoff together to a sewage treatment plant or disposal site. This means that during rain events, the sewage gets diluted, resulting in higher flowrates at the treatment site. Uncontaminated stormwater simply dilutes sewage, but runoff may dissolve or suspend virtually anything it contacts on roofs, streets, and storage yards. As rainfall travels over roofs and the ground, it may pick up various contaminants including soil particles and other sediment, heavy metals, organic compounds, animal waste, and oil and grease. Combined sewers may also receive dry weather drainage from landscape irrigation, construction dewatering, and washing buildings and sidewalks. Combined sewers can cause serious water pollution problems during combined sewer overflow (CSO) events when combined sewage and surface runoff flows exceed the capacity of the sewage treatment plant ...

Balsas River
The Balsas River (Spanish Río Balsas, also locally known as the Mezcala River, or Atoyac River) is a major river of south-central Mexico. The basin flows through the states of Guerrero, México, Morelos, and Puebla. Downstream of Ciudad Altamirano, Guerrero, it forms the border between Guerrero and Michoacán. The river flows through the Sierra Madre del Sur, and empties into the Pacific Ocean at Mangrove Point, adjacent to the city of Lázaro Cárdenas, Michoacán. Several rapids along the course of the Balsas River limit its navigability and thus the river has been largely used for generation of hydroelectric power, flood control and irrigation. History The Balsas River valley was possibly one of the earliest maize growing sites in Mexico, dating from around 9200 years ago. Though it is known that successive communities of Yop, Coixica, Matlatzinca ( Chontal), Tlahuica and Xochimilca with Nahua succeeding in the end have lived in the region, archeological excavation ...

Cutzamala River
The Cutzamala River is a river of Mexico. It originates in the Trans-Mexican Volcanic Belt of Central Mexico in the state of Michoacán. Dams on the upper portion of river provide water to Mexico City, via an aqueduct over the mountains known as the Cutzamala System. The lower Cutzamala forms part of the border between Michoacán and Guerrero states. It empties into the Balsas River near Ciudad Altamirano, Guerrero.

Lerma River
The Lerma River ( es, Río Lerma) is Mexico's second longest river. It is a river in west-central Mexico that begins in Mexican Plateau at an altitude over above sea level, and ends where it empties into Lake Chapala, Mexico's largest lake, near Guadalajara, Jalisco. Lake Chapala is the starting point of Río Grande de Santiago, which some treat as a continuation of the Lerma River. In combination, the two are often called the Lerma Santiago River ( es, Río Lerma Santiago). The Lerma River is notorious for its pollution, but the water quality has demonstrated considerable improvement in recent years due mostly to government environmental programs and through massive upgrading projects of sanitation works. Course The Lerma River originates from the Lerma lagoons near Almoloya del Río, on a plateau more than above sea level, and southeast of Toluca. The lagoons receive their water from springs rising from basaltic volcanics that flow down from Monte de Las Cruces. These are lo ...

Cubic Metre Per Second
A cubic metre per second (m3s−1, m3/s, cumecs or cubic meter per second in American English) is the unit of volumetric flow rate in the International System of Units (SI) equal to that of a stere or cube with sides of in length exchanged or moving each second. It is popularly used for water flow, especially in rivers and streams, and fractions for HVAC values measuring air flow. The term cumec is also used, as shorthand for "Cubic metres per second", with the plural form ''cumecs'' also common in speech. It is commonly used between workers in the measurement of water flow through natural streams and civil works, but rarely used in writing. Data in units of cumec are used along the y-axis or vertical axis of a flow hydrograph, which describes the time variation of discharge of a river (the mean velocity multiplied by cross-sectional area). A moderately sized river discharges in the order of 100 cumecs. Conversions References See also * Standard litre per minute * Conver ...

Texcoco, Mexico State
Texcoco de Mora () is a city located in the State of Mexico, 25 km northeast of Mexico City. Texcoco de Mora is the municipal seat of the municipality of Texcoco. In the pre-Hispanic era, this was a major Aztec city on the shores of Lake Texcoco. After the Conquest, the city was initially the second most important after Mexico City, but its importance faded over time, becoming more rural in character. Over the colonial and post-independence periods, most of Lake Texcoco was drained and the city is no longer on the shore and much of the municipality is on lakebed. Numerous Aztec archeological finds have been discovered here, including the 125 tonne stone statue of Tlaloc, which was found near San Miguel Coatlinchán and now resides at the Museum of Anthropology in Mexico City. Much of Texcoco's recent history involves the clash of the populace with local, state and federal authorities. The most serious of these is the continued attempts to develop an airport here ...

Xochimilco
Xochimilco (; nci, Xōchimīlco, ) is a borough (''demarcación territorial'') of Mexico City. The borough is centered on the formerly independent city of Xochimilco, which was established on what was the southern shore of Lake Xochimilco in the precolonial period. Today, the borough consists of the 18 , or neighborhoods, of this city along with 14 , or villages, that surround it, covering an area of . The borough is in the southeastern part of the city and has an identity that is separate from the historic center of Mexico City, due to its historic separation from that city during most of its history. Xochimilco is best known for its canals, which are left from what was an extensive lake and canal system that connected most of the settlements of the Valley of Mexico. These canals, along with artificial islands called chinampas, attract tourists and other city residents to ride on colorful gondola-like boats called around the of canals. This canal and chinampa system, as a ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Distribution System
A water distribution system is a part of water supply network with components that carry potable water from a centralized treatment plant or wells to consumers to satisfy residential, commercial, industrial and fire fighting requirements. Definitions Water distribution network is the term for the portion of a water distribution system up to the service points of bulk water consumers or demand nodes where many consumers are lumped together. The World Health Organization (WHO) uses the term water transmission system for a network of pipes, generally in a tree-like structure, that is used to convey water from water treatment plants to service reservoirs, and uses the term water distribution system for a network of pipes that generally has a loop structure to supply water from the service reservoirs and balancing reservoirs to consumers. Components A water distribution system consists of pipelines, storage facilities, pumps, and other accessories. Pipelines laid within public rig ...
