Make the simple syrup according to this recipe. Allow to cool to room temperature.

In a large pitcher, place the water, lemon juice, and simple syrup. Stir to combine.

If making ahead, chill the lemonade in the refrigerator until ready to serve. If serving right away, stir in several handfuls of ice. Taste and add more simple syrup if desired.

Pour into glasses filled with ice and garnish with lemon wheels.
