We just dug a new borewell last week and looking for suggestions for motor selections. The borewell details:
Place; Tirupattur, Vellore District, Tamil Nadu
Diameter : 6.5 inches
Depth: 700 ft
Type: New
Water level : first water at 45 feet, and continued until 120 feet. After that no water found until 700ft
PVC casing : upto 75 feet
Loose soil found at the start and hence another 10 inches pipe kept for first 16 feet (as the bore initially become like a well and bore could not be be dug further).
Yield: Driller said the water yield is appoximately 1.5 inches though he didnot study it with any specific techniques.
Planned overhead tank: at a height of 30 feet from ground.
Kindly advice on type of motor to be selected.
