Basic Environmental Engineering

---

Environmental engineering is one of the most popular, complex and fast growing disciplines in
engineering. The scope of environment includes issues from public health, aesthetics, and impact
of all development activities, pollution control legislation, standards, regulations, guidelines and
their enforcement. Traditionally the application of engineering principles for the protection and
enhancement of the quality of environment and protection of public health was called as sanitary
engineering or public health engineering. Around 1968 this was changed to environmental
engineering.

For conceiving environmental engineering, one has to consider the definition of engineering
itself. Engineering may be defined as the application, under limits of scientific principles for the
planning, design, execution, operation and maintenance of structures, equipment and systems for
the development and benefit of the society. Here the word benefit is more important than the
development. The so-called development in some cases may not be in real benefit of the society.
The environmental engineer plans, designs, executes, operates and maintains the water,
wastewater and solid waste management plants. Clean, bacteriologically safe, potable drinking
water protects and enhances public health. Liquid and solid waste management is a necessary step
for healthy living. They also deal with air pollution control. The resulting pure cleaner air is conducive
to people’s good health and prevents the building and other materials from the harmful effects of air
pollution. The environmental engineer cares for the energy requirements of the society and the ways
and means to protect the environment against the various pollutions created through the production
and consumption of various goods and comfort conditions. It is the duty of environment engineer to
assess the environmental impacts of the various development and other activities. In general one has
to work to have sustainable and holistic development. Of course there are always constraints of
resources, knowledge, human nature, social and racial considerations that limit the achievement of
these goals.

Therefore the environmental engineering is defined as the application of scientific and engineering
principles, under limits, for the protection and enhancement of the environment that includes the
biotic and abiotic both components.

The environment exists in dynamic equilibrium of its biotic (living) and abiotic (non-living)
elements. The solar energy induced photosynthesis synthesizes the carbon as the plant tissue and
we get matter in various forms from the trees. The carnivores, humans and animals consume the
edible matter. They convert it into the energy required to sustain their lives. Their excreta comes near
to the nature and the natural scavengers, bacteria and others convert it into inorganic matter like
nutrients due to the biological decomposition. The roots of the plants, to form the edible matter again,
extract these nutrients. Like this the nutrient cycle, material cycle, energy cycle and other cycles like
hydrological cycle keep on existing until there is a great shock given by the human beings.

“Nature has enough for satisfying everybody’s need but not for anybody’s greed”. Human
beings have lost their natural wisdom in want of power to overcome the nature. Since mid century the
word has lost nearly one fifth of the topsoil from its cropland, a fifth of its tropical rainforests and
animal species. Rapid industrialization and urbanization has increased carbon dioxide levels to the
point where global climate is being affected. The protective ozone shield is being depleted because of
the chlorofluorocarbons. The forest, which is a complete ecosystem, is being converted into dead
forests. The biodiversity is reducing everywhere in the world.

Biodiversity gives strength to the ecosystem against crisis. Only a well-diversified community
can sustain against the extreme conditions. In quest of comfort conditions and well-secured life we
have adopted a system, which is completely away from nature. We have made computers for paper
less office work but the energy in making and running the computers is more than the savings made.
Of course there are other advantages of computers in computation, up keeping of data etc. But the
materials used in making the computer and the disposal of the obsolete ones are drastically against
the environment.
