In a world of bottled water, hope springs eternal for Mountain Valley Spring. Through its Mountain Valley Spring Water division, the company bottles and sells natural spring water, collected from three neighboring natural springs, via such brands as Mountain Valley Spring Water, Mountain Valley Sparkling Water, and Diamond Spring Water. The company uses both glass and PET (polyethylene terephthalate resin) bottles. Its Veriplas division makes and sells preforms and finished PET bottles ranging in sizes from 10 ounces to 4 gallons. The company sells its bottled water through grocers such as H-E-B, Sprouts Farmers Market, and Whole Foods Market. Mountain Valley Spring filed to go public in late 2011.
