Where is the Best Water in Amarillo?

I am a water connoisseur.  I drink a lot of it each day, I try to drink half my body weight in ounces per day.  So it's gotta be good water.

I was recently introduced to the flavored iced water at Sonic.  I didn't know they did this and I fell in love.  However, I love a good bottle of water, so I was wondering, has the best water in Amarillo?
