The civil engineer plays an important role in Environmental Engineering in the following ways:
1. Sensible use of water, land, and air so that the environmental pollution and degradation is minimized 2. Engineers study water, soil and other pollution problems and develop solution to solve and control them. 3. Facilities like water supply for drinking, agriculture, ground water quality is developed by civil engineers. 4. Thus it includes planning, designing, construction of water and waste water treatment plants, and disposal of solid waste.
