A water table is the underground level below which the ground is completely filled with water. Think of it like an invisible line underground - above it the soil has both air and water in its spaces, below it all spaces are filled with water. This is important for water supply professionals because it affects where we can place wells, how deep we need to dig, and how much water we can sustainably pump out. The height of this level can change with seasons, rainfall, and human activities like pumping. Water supply professionals often need to monitor, measure, and manage the water table to ensure sustainable water supply for communities.
