The main purpose of a “Water
Treatment plant” is to improve water quality to make it appropriate for specific
purpose or end use. Here, the main function and purpose of a water treatment
plant is to prepare water for safe consumption by the people by eliminating
contamination present in the water. Contaminants may be suspended
particles, parasites, Bacteria, algae, virus and fungi etc. It involves reduction
of suspended solids including Iron and manganese. These metals are great harm
for public health of several developing countries.

PROBLEMS ACCESSING WATER RESOURCES
- The human population has harnessed many of the world’s natural waterways—building
dams, water wells, vast irrigation systems and other structures that have
allowed civilizations to grow and thrive. Water system increasingly stressed
and some rivers, lakes, and aquifers are drying.
- Water pollution comes from many sources including pesticides and fertilizers
that wash away from farms, untreated human wastewater, and industrial waste.
- Climate change has caused receding glaciers, reduced stream and river flow, and shrinking lakes and ponds.
- Ground water- about 30% of Earth's fresh water laid deep underground in aquifers. And it's extracted daily for farming, drinking and industrial processes – often at dangerously unsustainable rates.
- Water infrastructure is causes of water lost during treatment, transportation and distribution. Also an enormous quantity of water lost due to bad sanitation every year.

Water is the basic need
for guaranteeing the life of
all living beings on the planet. To access
water, sanitation and hygiene is a fundamental right of the
people and yet billions of people throughout the world are battling daily
against enormous difficulties to accessing the most basic need of water and the
Water Treatment Plant can fulfil to access most hygiene water for the people
through the world.
CONCLUSSION
About 2.1 billion people since 1990 have gained improved access to better water and sanitation services; the decreasing availability of quality drinking water is an important problem afflicting all continents. It is estimated that at least 1 out of every 2 people will be affected by water scarcity by 2050. The solution for the water crisis of different countries is to protect fresh water and it production. Waste water treatment can solve partly to this situation. Desalination of sea water can be a great solution of water crisis throughout the globe. So, importance should be given to water, it treatment and plant to solve the water crisis world wide.
