Drainable

Drainable is an adjective meaning capable of being drained, i.e., able to be emptied of liquid, moisture, or other contents through a drain, outlet, or natural process. The term is used in several fields, notably medicine, engineering, and soil science, where it describes objects, systems, or conditions that allow removal of accumulated fluids.

In medical contexts, a drainable wound or fistula is one that exudes fluid that can be evacuated. Drainage volume and characteristics are monitored to guide treatment, influence dressing selection, and assess healing or infection risk. Management typically aims to control moisture, protect surrounding tissue, and promote healing, using absorptive dressings, drainage devices, or negative-pressure wound therapy when appropriate.

In engineering and plumbing, drainable components are designed to allow complete or rapid drainage of liquids through outlets or valves. Proper drainage design helps prevent stagnation, reduces corrosion or contamination risk, and facilitates cleaning and maintenance.

In soil science and agronomy, the term may appear in discussions of drainable porosity or drainable water, referring to the portion of water that can drain from soil under gravity. This concept helps characterize soil drainage performance and influences irrigation and drainage planning.
