dewatering
Removing excess moisture
Dewatering is removing water from something—typically soil, sludge, or an excavation site.
Construction projects dewater foundations to work in dry conditions.
Wastewater treatment plants dewater sludge to reduce volume before disposal.
They had to dewater the basement after the flood.
