The Aqua Water Bar by Luqel harvests its water the old-fashioned way — from the faucet. The government says tap water is safe to drink and meets international standards, though many Dubai residents prefer bottled water. Then they use a micro-dosing system designed by the German water filtration company Luqel to inject minerals. They offer to match the mineralization of high-end water brands, catering to all types of water fans, Alpine or Arctic-sourced. “Our water sommeliers have designed the drinks to suit your needs and mood,” says Roia Jabari, the managing director. “We can give you the perfectly mineralized recipe.” “Runners Heaven,” which is high in sodium and potassium, is designed for joggers recovering from the scorching desert heat. “Vegan’s Choice” offers minerals that could be lacking in a strictly herbivorous diet. Customers can fill up their bottles with any of the mineral blends for around 50 cents per 500 milliliters (16 fluid ounces) or pay more for mocktails.
