unpumpable
Impossible to extract
Unable to be pumped.
Liquids may be unpumpable because they're too viscous, too shallow, or the equipment has failed: The sludge had thickened to an unpumpable consistency.
The term appears in industrial and environmental contexts—oil too thick to extract, septic tanks too solidified to service, floodwater beyond the capacity of available pumps.
