Springs:

Springs are formed due to emergence of ground water on the earth surface owing to various reasons. Springs may be perennial or intermittent. Normally very small amount of water can be tapped through springs, therefore these are used for supplying water for very small town/localities especially in hilly terrain, that too if the water flow is consistent. The quality of spring water depends on geological and topographical conditions of the strata through which spring water emerges. It may be hard, soft or may contain sulphur or other impurities depending on the type of soil/rock strata through which it passes. The spring water through shallow strata is more prone to get affected by surface pollution as compared to deep water springs.

Normally there are three types of springs as given below:

(a)        Surface spring

(b)       Gravity spring

(c)        Artesian spring
