What do sump pits collect and remove from a construction site?

Explanation:
Sump pits are used to handle groundwater. They’re placed at the lowest point of an excavation so water that seeps through the surrounding soil into the trench collects in the pit. A pump then removes that water, keeping the work area dry and reducing pressure on the walls. Surface runoff and rainwater are typically managed by surface drainage systems, not by sump pits, and sewage is unrelated to this dewatering purpose. So the water sump pits remove is groundwater.
