Environmental Engineering is a unique discipline of engineering which relates to a study of the environment at large. This sub-discipline resorts to the use of science like chemistry, biology, microbiology, hydrology, mathematics, ecology and hydraulics, to conserve the environment to maintain a healthy space for the organisms to live in. In all important respects, the study of Environmental Engineering is also concerned with the protection of human health and ensuring that human life benefits largely from the ecosystem. Environmental Engineering is mainly concerned with the study and development of clean technology that has minimum impact on the environment.

Environmental Engineers work to ensure public health and environmental needs. Their work involves preventing contamination of the air, soil, and water. Some of the projects of an Environmental Engineer extend to that of determining water storage, monitoring disinfection needs for drinking water facilities or wastewater facilities. This field of study provides students with an exciting work environment as they have the opportunity to work indoors and outdoors, simultaneously. Developing alternative energy sources, waste management, recycling, and water conservation are some of the topics that are covered by the discipline.
