Environmental Engineering is the branch of Civil Engineering refers to the use of scientific processes to help improve the Earth’s environment to provide healthier land, water and air for human use and to find new ways to pollution free environment. It uses the scientific and engineering principles for protection of peoples from adverse environmental effects and improve the environment for standard living.
Scope and importance
The scope and importance of Environmental Engineering is actually larger than one might think and largely deals with the topics that were listed above. It is broad and scope and deals with major issues such as the treatment of water and air pollution to smaller but still completely relevant issues like recycling everyday items and storing solid wastes in landfills.
Environmental engineers work variety of environments because of the nature of tasks. The employment of environment engineers is expected to grow from 15% to 22% by 2022. Apart from social and ecological impact, environmental engineers are also involved in protection of wildlife. They also work as consultants and provide their services to clients to protect our environment from various environmental hazards, and clean up hazardous sites.
Scope of Environmental Engineering
Environment Impact and Mitigation
Engineers and scientists apply scientific and engineering principles to evaluate if there are likely to be an adverse impact on water, air, soil, land quality, flora and fauna, ecological impact, noise impact or visual impact. The overall goal of environmental engineers is to identify, assess and evaluate the environmental impacts of man made plans, projects and laws to see if there are any affects whatsoever on water, air, habitat, agriculture, plants and animals, and the ecosystem. In this sense, environmental engineering encompasses the protection of human health and preserving the natural environment using scientific and engineering processes.
Water Supply and Treatment
Environmental engineers work to portable and agricultural use. It is their job to assess water within a water basin and determine supply of available water, the cycles of water movement throughout the seasons, and the treatment of water for various uses. This is done to severely minimize the risk of diseases that can be caught from the drinking and/or contact of water. This is why water distribution systems are built to meet irrigation standards for civilian use.Water Treatment
Water pollution is closely tied to water supply and treatment. It essentially deals with the waste put into water from sewer systems, outhouses and septics in both rural and urban areas. Environmental engineers design specific systems to carry the polluted water away from civilized areas and release the waste into the environment, most often into the ocean, and in more landlocked areas, rivers and lakes.Polluted Water
Air Pollution Management
Environmental engineers design manufacturing and combustion processes to ensure the air pollutants are at acceptable levels in the atmosphere where the toxins can have minimal effects on people. These include emissions from automobile exhausts, No2, So2, organic compounds, and organic acids.Air pollution
Solid Waste Management Solid waste management deals with solid waste materials produced by human activity, whether straightforwardly or obliquely. Solid waste management also focuses on the recovery of resources to delay the human consumption of natural resources. Different methods are used to limit the harmful solids that are released into the environment. The objective of solid waste management is to reduce the harmful effects of solid, liquid or gaseous substances on the environment. Solid waste management also encompasses reuse and recycling of everyday materials, the minimization of waste, the storage and transfer of wastes, disposing of solid wastes at landfills, and policies and regulations regarding the above.
