Step 1

Add the blueberries and 1/3 cup water to a medium sized saucepan and place over medium heat.  Cook until blueberries are starting to burst open, about 5 minutes, stirring often.  Let blueberry mixture cool and then add to a blender and blend.

Step 2

Pour the blueberry syrup into a large pitcher and then add the fresh lemon juice, maple syrup and 7 cups of water.  Mix well and then pour into cups filled with ice or refrigerate until ready to use.
