4 1/2 cups water
1 1/2 cups tequila
1 (12 fluid ounce) can frozen limeade
1/2 cup triple sec (orange-flavored liqueur)
1 whole lime, cut into 6 wedges
Mix the water, tequila, limeade, and orange liqueur in a freezer-proof container with a lid; stir. Cover and store in freezer until it reaches a slush-like consistency, about 24 hours. Serve in glasses garnished with lime wedges.
