Dug wells are specifically designed to access shallow unconfined aquifers. Being shallow and exposed to the surface, dug wells are particularly vulnerable to contamination from surface sources like road salt, fertilisers, and septic systems. Dug wells have depths between 3 m and 10 m and are prone to drought conditions when the water table drops.

It serves the drinking water needs of nearly half of the humanity, including almost everyone who lives in rural areas. The largest use for groundwater is to irrigate crops. In India, about 90% of groundwater is consumed by irrigation alone. At 250 billion cubic meters per year, […]
