• Environmental Engineering is a branch of engineering
that was developed to overcome serious environmental
contamination problems caused by human activities and
the waste they produce.
 the integration of sciences and engineering principles to
develop processes that will improve the environment.
• Environmental engineering is a fairly new science, but it
is developing very rapidly and expertise in this science is
needed now and in the future.

• Pollution can be caused by various sources.
• The spread of pollution can be found in soil,
water and air throughout planet Earth.
• Air pollution, water source pollution, land
pollution, hazardous waste, both solid and liquid,
are found everywhere.
• Environmental engineering studies how to deal
with pollution and manage waste to protect the
environmental health of the earth and its
inhabitants.

• Environmental engineering is closely related to civil
engineering and public health.
• Clean water supply and sewage systems are
examples of public facilities designed by civil
engineers to control environmental pollution and
protect public health.
• Water availability is an important problem in every
civilization.

• When water sources are polluted by pollutants, it
will cause problems for the environment and public
health.
• Example: ground water sources are contaminated
by E. Coli bacteria due to poor environmental
sanitation.

• In the 18th and 19th centuries, poor residents in
European cities were unable to access clean water
because rivers were polluted, clean water was
expensive, or there were no water sources.
• In London, at that time many poor people begged
for water or even stole water. At that time there
were also many disease outbreaks.

• Water filtration technology began to be used
around the 19th century. The first successful use of
water filtration technology was recorded in Parsley,
Scotland in 1804.
• The use of chlorine as a disinfectant in water was
first carried out in Belgium in 1902 and in America
in 1908.
• Between 1900 – 1920, deaths from infectious
diseases decreased drastically, and is believed to be
the result of the increasingly clean water supplied
to the population.

• Disposal of human waste can be a serious problem
for public health.
• In the past, many people dumped human waste
directly into drainage channels or rivers.
• In the 19th century, the river Cam (in Cambridge)
and the river Thames (in London) were heavily
polluted for many years.
• Many residents suffer from cholera.

• In the 1850s, the "Great Sanitary Awakening"
campaign was launched to improve
environmental sanitation.
• Modern environmental engineering began in
London in the 1940s following the Great Stink.
• Civil engineers are responsible for developing
technical solutions to problems related to water
and waste.
• Civil engineering engineers must understand the
basic principles of ecology and ecosystems so as
not to damage the environment and ecosystem.
