Delcol United Marketing (M) Sdn Bhd or just simply Delcol has its history dated back to 1988 when two young entrepreneurs, Mr. Liew Kian Seng and his wife Miss Tan Mui Kiang, who were then in their 20's, ventured into the business of marketing water filters. Initially, they set up a small proprietary business under the name of United Marketing. Over the last 13 years, business grew at a phenomenal rate and from a small business outfit, it has transformed into a large corporate entity with a retail chain of 16 outlets throughout the Kiang Valley, Johore Bahru and Kota Kinabalu and Melaka. Today, Delcol has received recognition from the Malaysia Book of Records as the largest retailer of water filtration systems in the country.
