Scoop out the watermelon, and place it into a large capacity blender. Add 2 cups of water, sugar, and lime juice and blend until smooth.
8 pounds watermelon, 2 to 3 cups water, ½ cup granulated sugar, 1 tablespoon freshly squeezed lime juice
Blend in more water and sugar as needed. Pour the juice through a fine mesh sieve into a large pitcher.
Strain it 2-3 more times as needed to get an even smoother juice, or leave it as is if you don’t mind juice with more pulp.
Chill until ready to serve. Pour it over ice and garnish with thinly sliced watermelon wedges and lime wedges if desired.
