In a saucepan, combine the sugar and 1/3 cup water and place over medium heat. Bring the mixture to a boil, then cook the sugar until dissolved but the syrup is still clear. Do not cook the sugar until it starts to turn color. Remove from heat and cool.
In a pitcher, combine the syrup, 8 cups water, the lemon juice, vodka and ice and stir to combine. Pour into tall glasses and enjoy!
