What can be considered a source of water supply?

A well is indeed a legitimate source of water supply as it extracts groundwater from underground aquifers, providing a direct supply of water for consumption and irrigation. Wells are typically drilled or dug to access subterranean water sources that are replenished by precipitation and other natural water movements, making them crucial in areas where surface water is not readily available.

While storage tanks, reservoirs, and rainwater harvesting systems play important roles in water distribution and management, they do not serve as primary sources of water in the same way that a well does. Storage tanks are used to hold water that has already been sourced, reservoirs are large-scale collections of surface water usually found in natural bodies, and rainwater harvesting systems collect precipitation but require a mechanism to store and use that water after it has been captured. Therefore, in the context of identifying a direct source of water supply, wells are rightly recognized for their function in drawing water directly from the ground.
