Which of the following is NOT a component of construction de-watering?

The correct choice highlights that excavating new foundations is not considered a component of construction de-watering. Construction de-watering primarily involves the removal of water to facilitate excavation and construction activities, helping to create a dry work area.

Pumping water to sediment basins, using geotextile filter bags, and creating sediment traps are all instrumental methods used during de-watering to manage and control sediment and water flow on a construction site. These techniques aid in reducing erosion and preventing sediment pollution in nearby water bodies. In contrast, excavating new foundations refers to the actual construction and site development process rather than the water management methods associated with de-watering.
