dewater
Extract liquid from
To dewater is to remove water from something—typically soil, a construction site, or industrial material.
The term appears in engineering and mining contexts where groundwater must be pumped out before work can proceed: We'll need to dewater the excavation before pouring the foundation.
Dewatering also describes processes that extract moisture from sludge or sediment.
