Without water there can be no life. Man and animals not only consume water but they also consume for their food. Vegetation in turn cannot grow without water. Growth of vegetation also depends upon bacterial action, while bacteria bed water in order to thrive.

The bacterial action can convert vegetable matter into productive soil. New plants which grow in this soil grow by sucking nutrients through their roots in the form of solution in the water. Thus an ecological chain is maintained.

Water maintains an ecological balance a balance in the relationship between living things and environmental in which they live.Organised community life require twin suffices of water supply and sewage disposal. Good sanitation cannot be maintained with adequate water supply system. Without proper disposal, the wastes of community can create intolerable nuisance, spread diseases and create order health hazards. The planning, design and operation of water and waste water systems are complex and undertakings and they require a high degree of skill and judgement. The work of construction and maintenance of water supply and waste water disposal systems in generally undertaken by government agencies mostly through Public Health Engineering in Environmental Engineering Departments consisting of Civil Engineers.

Environmental engineering is a professional engineering discipline that takes from broad scientific topics like chemistry, biology, ecology, geology, hydraulics, hydrology, microbiology, and mathematics to create solutions that will protect and also improves the health of living organisms and improve the quality of the environment. Environmental engineering is a sub-discipline of and.Environmental engineering is the application of scientific and engineering principles to improve and maintain the environment to:. protect human health,. protect nature's beneficial ecosystems,. and improve environmental-related enhancement of the quality of human life.Environmental engineers devise solutions for, and control, recycling,. They design and systems, and design plans to prevent and improve sanitation in urban, rural and recreational areas. They evaluate hazardous- systems to evaluate the severity of such hazards, advise on treatment and containment, and develop regulations to prevent mishaps.

They implement, as in assessing the environmental impact of proposed construction projects.Environmental engineers study the effect of technological advances on the environment, addressing local and worldwide environmental issues such as, water pollution and air pollution from and.Most jurisdictions impose licensing and registration requirements for qualified environmental engineers. Further information: Ancient civilizations Environmental engineering is a name for work that has been done since early civilizations, as people learned to modify and control the environmental conditions to meet needs. As people recognized that their health was related to the, they built systems to improve it.

The ancient (3300 B.C.E. To 1300 B.C.E.) had advanced control over their water resources.

The public work structures found at various sites in the area include wells, public baths,water storage tanks, a drinking water system, and a city-wide sewage collection system. They also had an early canal irrigation system enabling large-scale agriculture.From 4000 to 2000 B.C.E., many civilizations had drainage systems and some had sanitation facilities, including the, Egypt, Crete, and the in Scotland. The Greeks also had aqueducts and sewer systems that used rain and wastewater to irrigate and fertilize fields.The first in Rome was constructed in 312 B.C.E., and from there, they continued to construct for irrigation and safe urban water supply during droughts. They also built an underground sewer system as early as the 7th century B.C.E.

That fed into the Tiber River, draining marshes to create farmland as well as removing sewage from the city. Modern era Very little change was seen from the fall of Rome until the 19th century, where improvements saw increasing efforts focused on public health. Modern environmental engineering began in in the mid-19th century when designed the first major system following the. The city's sewer system conveyed raw sewage to the, which also supplied the majority of the city's drinking water, leading to an outbreak of. The introduction of drinking water treatment and sewage treatment in industrialized countries reduced from leading causes of death to rarities.The field emerged as a separate academic discipline during the middle of the 20th century in response to widespread public concern about water and air pollution and other environmental degradation. As society and technology grew more complex, they increasingly produced unintended effects on the natural environment.

One example is the widespread application of the pesticide to control agricultural pests in the years following. While the benefits were outstanding and crop yields increased dramatically, reducing world hunger, and was controlled better than ever before, the pesticide brought numerous bird species to the edge of extinction due to its impact on their reproductive cycle. The story of DDT as vividly told in 's (1962) is considered to be the birth of the modern environmental movement, which led to the modern field of 'environmental engineering.' Education Many universities offer environmental engineering programs through either the department of or and also including electronic projects to develop and balance the environmentalconditions.

Environmental engineers in a civil engineering program often focus on hydrology, water resources management, and water and wastewater treatment plant design. Environmental engineers in a chemical engineering program tend to focus on environmental chemistry, advanced air and water treatment technologies, and separation processes.

Plant,There are numerous technologies. A wastewater treatment train can consist of a primary clarifier system to remove solid and floating materials, a secondary treatment system consisting of an basin followed by and or an system and a secondary clarifier, a tertiary biological removal system, and a final process. The aeration basin/activated sludge system removes organic material by growing bacteria (activated sludge). The secondary clarifier removes the activated sludge from the water.

The tertiary system, although not always included due to costs, is becoming more prevalent to remove nitrogen and and to disinfect the water before discharge to a surface water stream or ocean outfall. Air pollution management Scientists have developed to evaluate the concentration of a pollutant at a receptor or the impact on overall air quality from vehicle and industrial emissions. To some extent, this field overlaps the desire to decrease and other emissions from combustion processes.Environmental impact assessment and mitigation. Water pollutionEnvironmental engineers apply scientific and engineering principles to evaluate if there are likely to be any adverse impacts to water quality, air quality, quality, and, agricultural capacity, ecology, and noise. If impacts are expected, they then develop mitigation measures to limit or prevent such impacts. An example of a mitigation measure would be the creation of in a nearby location to mitigate the filling in of wetlands necessary for a road development if it is not possible to reroute the road.In the United States, the practice of environmental assessment was formally initiated on January 1, 1970, the effective date of the (NEPA).

Since that time, more than 100 developing and developed nations either have planned specific analogous laws or have adopted procedure used elsewhere. NEPA is applicable to all federal agencies in the United States. Regulatory agencies Environmental Protection Agency The (EPA) is one of the many agencies that work with environmental engineers to solve key issues. An important component of EPA's mission is to protect and improve air, water, and overall environmental quality in order to avoid or mitigate the consequences of harmful effects.See also.
