As a core component of Environmental Engineering, Water and Wastewater Treatment applies scientific and engineering principles to design, operate, and manage systems for purifying water. The discipline has two primary functions: treating raw water sources to produce safe, potable water for human consumption, and treating municipal and industrial wastewater to remove harmful contaminants before its safe release back into the environment. Through a combination of physical, chemical, and biological processes, this field is essential for protecting public health from waterborne diseases and preserving the ecological integrity of aquatic ecosystems.

Air Pollution Control is a critical field within environmental engineering that applies scientific and engineering principles to reduce, remove, or prevent the emission of harmful substances into the atmosphere. This involves the design, implementation, and operation of technologies to manage pollutants such as particulate matter, sulfur oxides, nitrogen oxides, and volatile organic compounds from sources like industrial facilities, power plants, and vehicles. Common control strategies include the use of devices like scrubbers, electrostatic precipitators, fabric filters, and catalytic converters, as well as process modifications to minimize pollutant formation, all with the ultimate objective of safeguarding public health, protecting ecosystems, and ensuring compliance with air quality standards.

Solid Waste Management is a critical discipline within environmental engineering that encompasses the systematic control of the generation, collection, storage, transportation, processing, and disposal of solid materials discarded from human and animal activities. The primary objective is to manage waste in a manner that is protective of public health, environmentally sustainable, and economically viable. This involves applying engineering principles to design and implement integrated systems that follow a waste hierarchy, prioritizing waste prevention, reuse, recycling, and resource recovery (such as composting or waste-to-energy conversion), with the safe disposal of residual waste in engineered facilities like sanitary landfills as the final option.

Environmental remediation is a branch of environmental engineering focused on the removal, treatment, or containment of contaminants from environmental media like soil, groundwater, sediment, or surface water. This process is critical for managing polluted sites and mitigating risks posed by hazardous substances to human health and the ecosystem. By applying scientific and engineering principles, remediation specialists design and implement strategies to clean up contamination, aiming to restore the affected area to a condition that is safe and acceptable for its intended future use.

Environmental Impact Assessment (EIA) is a systematic process central to environmental engineering that evaluates the potential environmental consequences of a proposed project, plan, or policy before it is approved and implemented. By identifying, predicting, and analyzing the potential impacts on the physical, biological, and socioeconomic environment, an EIA serves as a critical decision-making tool for regulators and developers. The process aims to ensure that potential adverse effects are addressed through the design of mitigation measures, the consideration of alternatives, and public consultation, ultimately promoting environmentally sound and sustainable development.

Water Resources Management is the comprehensive process of planning, developing, distributing, and managing the optimal use of water resources. As a field within both Engineering and Environmental Engineering, it involves the design and operation of physical infrastructure like dams, reservoirs, and treatment plants, while simultaneously addressing the critical need for sustainability, water quality protection, and ecosystem health. The central challenge lies in balancing the often-competing demands of agriculture, industry, domestic consumption, and environmental preservation to ensure the equitable and efficient allocation of water for current and future generations.

As a critical discipline within Environmental Engineering, Plastic Waste Management applies systematic engineering principles to manage the entire lifecycle of plastic materials, from their generation to final disposal. This field encompasses a hierarchy of preferred strategies, including source reduction, reuse, and various forms of recycling such as mechanical and advanced chemical processes that break down polymers into new feedstocks. It also involves the engineering of waste-to-energy systems and the design and operation of sanitary landfills for residual waste, with the overarching objective of minimizing environmental pollution, conserving resources, and transitioning towards a circular economy by transforming plastic waste from a liability into a valuable resource.
