Environmental Engineering
Environmental Engineering is a multidisciplinary branch of civil engineering that focuses on protecting and improving the natural environment to safeguard human health and promote sustainable development. It involves the study and application of scientific and engineering principles to control pollution, manage natural resources, and design systems for water supply, wastewater treatment, solid waste management, air pollution control, and environmental impact assessment.
Course Chapters
Water & Water Treatment
The chapter discusses various sources of water, such as surface water, groundwater, and harvested rainwater, along with their associated quality issues. It outlines the water quality requirements for different beneficial uses, sets standards, and introduces water quality indices. Additionally, it elaborates on water safety plans and the components of water supply systems along with treatment processes to ensure safe drinking water.
Sewage & Waste Water Management
This chapter covers the fundamental aspects of sewage and wastewater management, including the definitions and differences between domestic sewage and stormwater. Key topics include the conveyance methods for sewage flow, various types of treatment systems, and the importance of proper disposal to mitigate environmental impact. Additionally, it highlights government initiatives aimed at pollution reduction and the recycling of treated wastewater for sustainable practices.
Air Quality & Air Pollution
Air quality and pollution are crucial aspects of environmental engineering, encompassing the composition and properties of air, the types of pollutants, their monitoring, and standards for air quality. Control measures range from source control to urban planning strategies aimed at reducing emissions and improving air quality. Understanding the chemistry of combustion and the impact of various factors on emissions is vital for effective pollution management.
Noise Pollution
Noise is defined as unwanted or disturbing sound that negatively impacts health and well-being. Measuring noise is crucial for assessing its impacts, with various instruments used, including sound level meters. Noise pollution is categorized into types, effects, and control methods, emphasizing the need for effective noise management for public health.
Solid Waste Management
This chapter covers the definitions, sources, and management of municipal solid waste (MSW), along with its environmental impacts. Key aspects include collection methods, treatment technologies, special solid waste types, and strategies for secure disposal. Additionally, it highlights the significance of hazardous waste management and the regulations governing it.
Building Plumbing
Building plumbing involves systems for water supply and wastewater disposal in structures, crucial for hygiene and health. It includes various plumbing types for residential and commercial use, with specific considerations for high-rise buildings to manage pressure and demand. The chapter discusses fixtures and fittings for efficient operation, alongside the essentials of system design, materials, and maintenance.
Government Authorities and Their Roles
Environmental management in India involves various levels of government authorities responsible for water supply, sewerage disposal, solid waste management, and pollution control. This chapter outlines the roles of central, state, and local bodies, highlighting their specific mandates and collaborative efforts. National missions further strengthen the framework for ensuring effective environmental governance and resource management.
