Tasty Arisu! Arisu promises to deliver upgraded premium water, without the taste and odor of tap water, which is perfectly free from tiny amounts of organic matter. As part of its promise to deliver the finest tasting water, the Seoul Waterworks has start- ed operation of an environmentally-friendly advanced water purification treatment system, incorporating ozone and granular activated carbon (or charcoal), in the Yeongdeungpo Water Purification Centerin June 2010 Plans are in place to expand this system to all of the purification centers in Seoul by 2012. Taste Up↑, Disinfectant odor down↓ Tap water chlorination is a necessary step to ensure the hygiene and safety of tap water by destroying harmful micro-organisms, but it may also add an unpleasant odor to the drinking water. To remove this odor, a system was adopted where- by only the minimum amount of chlorine was added at the purifica- tion plant, then a minimum amount again at the water supply reservoir and circulating pump plant. By dis- persing the injection of chlorine across multiple steps, instead of adding it once at the water purification plant, as in the past, the unpleasant odor can be signifi- cantly reduced. Premium Quality and Premium Service! Arisu’s real-time information about the water quality is available on the Seoul Waterworks homepage and on mobile devices. Such information will continue to be accessible everywhere and anytime through more and more media channels in the future. We will continue our R&D efforts so that customers can trust and drink tasty Arisu water. 9 Arisu Water Purification Center Production Facilities and Water Supply Water supply facilities: Water pipe length: 13,914 km.
