Tubewells offer several advantages, including efficient groundwater extraction, reduced surface water evaporation, and the ability to access deep aquifers, which can be crucial in arid regions. They also provide a reliable water source for irrigation and drinking purposes. However, disadvantages include the risk of over-extraction leading to groundwater depletion, potential contamination of aquifers, and high initial installation and maintenance costs. Additionally, tubewells can contribute to land subsidence and affect nearby water bodies and ecosystems.
Disadvantage of a tube well: -It is not possible where water-table is low. -If the groundwater is brackish then irrigation is not possible.
