Water Management In Dhaka
Water management in Dhaka faces numerous challenges such as Flood, flooding, poor service quality, Overdrafting, groundwater depletion, inadequate sanitation, Water pollution, polluted river water, unplanned urban development, and the existence of large Slum, slums. Residents of Dhaka have one of the lowest Water tariff, water tariffs in the world, which limits the utility's capacity to invest. The utility in charge of water and sanitation in Dhaka, Dhaka WASA, addresses these challenges with a number of measures. Dhaka WASA said in 2011 that it achieved a continuous water supply 24 hours per day 7 days a week, an increase in revenues so that operating costs are more than covered, and a reduction of water losses from 53% in 2003 to 29% in 2010.Taqsem Khan (2011The performance challenges of Dhaka WASA, in Global Water Intelligence: Focusing on performance Global Water Summit 2011, p. 50-52. In the future DWASA plans massive investment to replace dwindling groundwater resources wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Privatization
Water privatization is short for private sector participations in the provision of water services and sanitation. Water privatization has a variable history in which its popularity and favorability has fluctuated in the market and politics. One of the common forms of privatization is public–private partnerships (PPPs).World Bank / Public-Private Infrastructure Advisory FacilitPublic-Private Partnerships for Urban Water Utilities: A Review of Experiences in Developing Countries by Philippe Marin, 2009, Overview, pp. 6-7. PPPs allow for a mix between public and private ownership and/or management of water and sanitation sources and infrastructure. Privatization, as proponents argue, may not only increase efficiency and service quality but also increase fiscal benefits. There are different forms of regulation in place for current privatization systems. Private sector participation in water supply and sanitation is controversial. Proponents of private sector participation argue that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dhaka (62)
Dhaka ( or ; bn, ঢাকা, Ḍhākā, ), formerly known as Dacca, is the capital and largest city of Bangladesh. It is the ninth-largest and seventh-most densely populated city in the world. Dhaka is a megacity, and has a population of 10.2 million residents as of 2022, and a population of over 22.4 million residents in Greater Dhaka. It is widely considered to be the most densely populated built-up urban area in the world. Dhaka is the most important cultural, economic, and scientific hub of Eastern South Asia, as well as a major Muslim-majority city. Dhaka ranks third in South Asia and 39th in the world in terms of GDP. Lying on the Ganges Delta, it is bounded by the Buriganga, Turag, Dhaleshwari and Shitalakshya rivers. Dhaka is also the largest Bengali-speaking city in the world. The area of Dhaka has been inhabited since the first millennium. An early modern city developed from the 17th century as a provincial capital and commercial center of the Mughal E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latrine
A latrine is a toilet or an even simpler facility that is used as a toilet within a sanitation system. For example, it can be a communal trench in the earth in a camp to be used as emergency sanitation, a hole in the ground ( pit latrine), or more advanced designs, including pour-flush systems. The term "latrine" is still commonly used military parlance, less so in civilian usage except in emergency sanitation situations. Nowadays, the word "toilet" is more commonly used than "latrine", except for simple systems like "pit latrine" or "trench latrine". The use of latrines was a major advancement in sanitation over more basic practices such as open defecation, and helped control the spread of many waterborne diseases. However, unsafe defecation in unimproved latrines still remained a widespread problem by the end of 2020, with more than 3 billion people affected (46 % of the global population). Eradication of this public health threat is one of the United Nations' 17 goals for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Septic Tank
A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater ( sewage) flows for basic sewage treatment. Settling and anaerobic digestion processes reduce solids and organics, but the treatment efficiency is only moderate (referred to as "primary treatment"). Septic tank systems are a type of simple onsite sewage facility. They can be used in areas that are not connected to a sewerage system, such as rural areas. The treated liquid effluent is commonly disposed in a septic drain field, which provides further treatment. Nonetheless, groundwater pollution may occur and can be a problem. The term "septic" refers to the anaerobic bacterial environment that develops in the tank that decomposes or mineralizes the waste discharged into the tank. Septic tanks can be coupled with other onsite wastewater treatment units such as biofilters or aerobic systems involving artificially forced aeration. The rate of accumulation of ...

Wastewater Treatment
Wastewater treatment is a process used to remove contaminants from wastewater and convert it into an effluent that can be returned to the water cycle. Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation). The treatment process takes place in a wastewater treatment plant. There are several kinds of wastewater which are treated at the appropriate type of wastewater treatment plant. For domestic wastewater (also called municipal wastewater or sewage), the treatment plant is called a sewage treatment plant. For industrial wastewater, treatment either takes place in a separate industrial wastewater treatment plant, or in a sewage treatment plant (usually after some form of pre-treatment). Further types of wastewater treatment plants include agricultural wastewater treatment plants and leachate treatment plants. Processes commonly used in wastewater treatment include phase sepa ...

Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, per ...

Asian Development Bank
The Asian Development Bank (ADB) is a regional development bank established on 19 December 1966, which is headquartered in the Ortigas Center located in the city of Mandaluyong, Metro Manila, Philippines. The bank also maintains 31 field offices around the world to promote social and economic development in Asia. The bank admits the members of the United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP, formerly the Economic Commission for Asia and the Far East or ECAFE) and non-regional developed countries. From 31 members at its establishment, ADB now has 68 members. The ADB was modeled closely on the World Bank, and has a similar weighted voting system where votes are distributed in proportion with members' capital subscriptions. ADB releases an annual report that summarizes its operations, budget and other materials for review by the public. The ADB-Japan Scholarship Program (ADB-JSP) enrolls about 300 students annually in academic institutions loc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dhaka City Corporation
Dhaka City Corporation (DCC) was the former self-governing corporation that was entrusted with the task of administering the municipal affairs of Dhaka. The incorporated area was divided into several wards. Each ward has an elected ward commissioner. The mayor of the city was elected by popular vote every five years, although the last mayoral election took place in 2002. The corporation was dissolved by the Local Government (City Corporation) Amendment Bill 2011 on 29 November, passed in the Parliament of Bangladesh, and formally ceased to exist on 1 December 2011, following the President's approval, making way for a Dhaka North and a Dhaka South city corporations. History Dacca Municipality, the predecessor of the city corporation, was established on 1 August 1864. The first elected chairman was Ananda Chandra Roy. Prior to that, a ''Committee for the improvement of Dacca'' was formed in 1823. The Act of 1884 added the provision of elected representatives called commissioners ...

Cyclone
In meteorology, a cyclone () is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). Cyclones are characterized by inward-spiraling winds that rotate about a zone of low-pressure area, low pressure. The largest low-pressure systems are polar vortex, polar vortices and extratropical cyclones of the largest scale (the synoptic scale). Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within smaller mesoscale meteorology, mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the tropical upper tropospheric trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the West African, Asia–Australian, the North American, and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area. Etymology The etymology of the word monsoon is not w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
