Pour the 3 cups of water into a pitcher and add mint leaves and chopped cucumber.
Allow the ingredients to sit in water for up to 20 minutes to allow the flavors to infuse.
Use a strainer to remove the mint leaves and cucumber from the water. This ensures most of the flavors remain in the water.
Add lime juice and sugar then stir.
Pour the ready drinks into caps and add lime to garnish and ice to keep it cool.
