Course Aim: To impart knowledge on local and global pollution issues, environmental sustainability and to provide basic skills for planning and design of environmental pollution control or mitigation measures.

Intended Learning Outcomes:

On successful completion of the course, the students should be able to;

➢    describe modes of water pollution, assess the effects of water pollution on water environment and to identify suitable options for control.

➢    describe the concepts of environmental sustainability, their impacts on humans and environment and options for mitigation.

➢    explain the concepts of potable water treatment and demonstrate the ability to plan a conceptual design of a conventional potable water treatment facility.

➢    explain the concepts of wastewater management and plan and design a wastewater collection system and conventional wastewater treatment units.

➢    compare available alternatives options and plan urban waste management systems for municipal solid waste collection, treatment and disposal and sanitary waste management.
