Civil Engineering is a broad discipline and civil engineers are involved in the development of the main infrastructure needed for society. It includes the assessment, planning, design, construction, operation and maintenance of infrastructural works such as road and rail systems, bridges and tunnels, docks, harbours, sea defences, airports, dams and reservoirs, water supply systems, pollution control systems, mines, and structures associated with energy supply.
Environmental Engineering is the application of science and engineering principles to improve the environment. Civil and Environmental Engineers work to provide healthy water, air and land for habitation by humans and other organisms and to remediate polluted sites. Professionals and practitioners of both Engineering and Environmental Science consolidate their efforts to tackle the present environmental issues such as waste disposal and water quality as well as planning for global issues such as climate change.
