Artesian Conditions in Sulphur Spring Valley

Diagrammatic section showing artesian conditions in Sulphur Spring Valley.

Artesian Wells differ from ordinary wells in that their waters are discharged by natural pressures on their reservoirs, so that pumping is not necessary to raise the water Such wells are therefore true springs.

An artesian well is a confined aquifer whose water is pressurized. Water will thus flow out of an artesian well without pumping.

A spring is a point where groundwater flows from the ground, and is thus where the aquifer surface meets the ground surface

Origin of Springs

When the outlet tube of the reservoir is siphon-shaped, the discharge of the spring becomes <em>periodical</em>. The spring continues to discharge its waters for a time, and then stops flowing, even during wet weather. After a certain interval it again charges. The times during which the spring continues to discharge are always practically the same. Hence the spring is called a periodical spring.
