What process involves removing stormwater or groundwater from excavation sites?

The process that involves removing excess stormwater or groundwater from excavation sites is construction de-watering. This technique is critical for ensuring a safe and dry working environment during construction activities. De-watering typically involves the use of pumps or other systems to lower the water table or remove water that accumulates in excavated areas.

This practice is essential for maintaining structural integrity, preventing soil erosion, and facilitating the proper handling of materials on site. Effective de-watering helps to avoid delays in construction and minimizes the impact of water on the stability of surrounding areas.

In contrast, the other options focus on related but distinct concepts. Surface water management deals more generally with the regulation and control of water flow across a landscape. Soil stabilization pertains to enhancing the structure and integrity of soil itself to prevent erosion or collapse. Runoff control deals with managing water that flows over land surfaces, preventing water pollution and erosion but does not specifically address removing water from excavations. Therefore, construction de-watering is the precise process required in this context.
