I. Introduction
- Need of water -
Water is an important and essential ingredient in our quest for survival on this planet. It is very essential for carrying out various metabolic processes in our body and also to carry out Hemoglobin throughout the body.

A daily average of 1 gallon per man is sufficient for drinking and cooking purposes. A horse, bullock, or mule drinks about 11 gallons at a time. standing up, an average allowance of 5 gallons should be given for a man, and 10 gallons for a horse or a camel. An elephant drinks 25 gallons, each mule or ox drinks 6 to 8 gallons, each sheep or pig 6 to 8 pints. These are minimum quantities.

One cubic foot of water = 6 gallons (a gallon = 10 lbs.).

In order to fulfill such a huge demand of water, it needs to be purified and supplied in a orderly and systematic way.

But with the increasing world population, the demand for drinking water has also increased dramatically and therefore it is very essential to identify resources of water from which we can use water for drinking purposes. Many available resources of water do not have it in drinkable form. Either the water contains excess of Calcium or Magnesium salts or any other organic impurity or it simply contains foreign particles which make it unfit and unsafe for
