A water table close to the surface affects excavation, drainage, foundations, wells and leach fields (in areas without municipal water and sanitation), and more.

When excavation occurs near enough to the water table to reach its capillary action, groundwater must be removed during construction. This is conspicuous in [[Berlin]], which is built on sandy, marshy ground, and the water table is generally 2 meters below the surface. Pink and blue pipes can often be seen carrying groundwater from construction sites into the [[Spree (river)|Spree]] river (or canals).{{citation needed|date = June 2023}}
