This document discusses different types of water wells, including tube wells, cavity wells, screened wells, slotted pipe wells, gravel packed wells, drilled wells, driven wells, and jetted wells. It also covers well depths from shallow to deep, types of aquifers like water table, subartesian, and artesian. Finally, it mentions open wells in unconsolidated formations, open wells in hard rock, and lined versus unlined open wells as well as dug-cum-bore wells for extracting water from hard rocks.
