What is dewatering?

Dewatering refers specifically to the temporary lowering of the groundwater level, making it easier to perform construction or excavation work in areas where water is present. This process is vital in construction and mining operations to prevent water from interfering with work, as excess water can create unstable conditions and hinder progress. By lowering the groundwater level, workers can safely access the site and complete necessary tasks without the risk of flooding or water damage.

The correct understanding of dewatering emphasizes its temporary nature, distinguishing it from processes like the permanent removal of water or sealing of a well bore, which serve different purposes. It is also important to note that while the controlled release of water from surface reservoirs is related to water management, it does not align with the definition of dewatering, which specifically focuses on lowering groundwater levels in a controlled manner to facilitate construction activities.
