Tapioca starch is an important agricultural export of Thailand. Water footprint of world native tapioca starch relatively high. Therefore, to collect data in real area from a case study of cassava starch factory, Ubon Ratchathani Province. Based on the analysis of water footprint of native starch production in the 2017/8-2020 by questioning and interviewing information in each production process. It found that 1 ton of native starch uses an average 4.35 tons of cassava fresh root, calculated from the amount of starch in the fresh root in average 23%. The highest water consumption was in the fresh root washing process, 57% of the total water consumption in the production process. When analyzing the actual water consumption and the virtual water volume in the starch production, found that water footprint of native starch 1 ton in the factory was 38.1 m<sup>3</sup>, separate in green, blue and grey were 0, 18.7 and 12.5 m<sup>3.</sup>, respectively. When embedded with water footprint of raw materials 253 m<sup>3/</sup>ton fresh root yield and fraction of product, the native tapioca starch products 1 ton had water footprint of 1,132.2 m<sup>3</sup> separate in green, blue and grey were 925, 18.7 and 187.5 m<sup>3</sup>, respectively. The database obtained from this research will support water footprint product labeling data, improve water consumption management in the processing process and enable environmentally friendly production in the future.</p>}, number={2}, journal={Thai Agricultural Research Journal}, author={Somkid, Sopita and Malipan, Anon and Lertkankasuk, Bencharat}, year={2022}, month={Oct.} }
