All well casings need to be grounded to the supply service ground grid. There is no better ground rod than that of a iron well casing. Grounding of the casing to the swimming pool will insure that if a fault occurs on the swimming pool electrical equipment, the safety equipment will trip the fault due to a good grounding system. In this case it is better to be over grounded that under grounded.
I dont know what an artesian wall is but an artesian well is a well that has been drilled and the driller hit a big water vein and the water from the well over flows the hole that is drilled and in turn the water overflows the well casing....there is nothing bad about an artesian well except that the ground around the well will always be damp and soggy.
the metal casing around it :)
the metal casing of the electric kettle
metal casing and tip of the bulb are connected to the circuit which allows electricity to flow through the wires and light up the bulb

Most people don't realize that almost all deep wells are Artesian. Artesian means that once you penetrate the actual water vein, the water in that well will rise up in the casing or bore hole to a certain level, which is the highest level of water in that particular vein. If your referring to a flowing well which is also Artesion, yes it is possible this well can go dry. It would probably take a large amount of pumping from nearby wells and possibly a lack of rain for several years to cause this to happen. There are a lot of variables.
give me the total casing progamme in drilling
casing drift is an inside diameter for the casing which allow any drift size pass through this casing with 1/8" under gouge

Elastic is inserted in the waistband casing.
