Jack and Jill went up a hill to fetch a pail of water; Nestl� Waters North America (NWNA) offers an easier alternative. The Swiss company (a unit of Nestl� Waters) entered North America in 1976 with Perrier Sparkling Mineral Water; it has since grown to represent about one-third of the bottled water market. Its portfolio boasts national top seller Nestl� Pure Life and a dozen or so international and regional water brands: Acqua Panna, Deer Park, Ozarka, Poland Spring, and S. Pellegrino, to name a few. Non-sparking waters generate some 90% of its sales. NWNA also sells tea. In addition to selling its products via retail outlets, the company provides home and office delivery.
