Answer: To cleanse
Step-by-step explanation:
A watershed is an area of land that drains or “sheds” water into a specific waterbody. Every body of water has a watershed. Watersheds drain rainfall and snowmelt into streams and rivers.
Whether it's traveling underground or on the surface, humans use the water in a watershed for:
drinking
washing
powering hydroelectric power plants
growing crops
literally anything that uses water
