In a pitcher, combine the water and sugar, stirring until the sugar dissolves.
Place the strawberries in a blender or food processor. Process until smooth. Add the strawberries and lime juice to the sugar water and stir well.
Serve over ice.
Notes
Depending on how sweet your berries are, you may need to adjust the sugar in the agua fresca to your preference a bit. For us, about a third of a cup is close to our preference.
