What is the purpose of dewatering in excavation?

The primary purpose of dewatering in excavation is to maintain soil stability by removing excess water. When water accumulates in an excavation site, it can lead to a reduction in the soil's load-bearing capacity, potentially causing soil instability and increasing the risk of collapses or cave-ins. Dewatering helps to lower the groundwater level and keep the soil conditions stable, which is crucial for ensuring the safety of the excavation site and the workers involved. By managing water presence effectively, dewatering contributes to safer working conditions and more reliable excavation processes.
