Water is often taken for granted, appreciated only for its ability to put out fires, nourish crops, and discipline bullying jocks at coming-of-age pool parties. Drink to water's victories with today's Groupon: for $9, you get a water member-card good for 10 refills of reverse-osmosis water at 18.9 litres each (an $18 value) at Vintner's Cellar Waterloo.
Vintner's Cellar Waterloo treats customers to 10 refills of high-quality water filtered using reverse osmosis, the same process winery staff use in crafting vinos. Guests serve themselves from a line of stainless steel taps and wishing wells at the front of the store, flanked by racks bearing 18.9 litre coolers (not included with this Groupon; customers may purchase one for $8 or bring their own container). In reverse osmosis, water is filtered through a semi-permeable membrane that sifts out up to 99.9% of its contaminants, pollutants, and wayward mermaids. A chemical- and electricity-free process, reverse osmosis sessions trump the 20% reduction of impurities house filtration systems generally remove from tap water. Purified water can then be used for winemaking, drinking, or to give lawn sprinkler tag the sophistication it's always deserved.
