5.4 Thailand

Freshwater augmentation is practised in Thailand for three main purposes; namely, for agricultural, industrial, and domestic uses. The status of freshwater augmentation technologies in Thailand is summarized in Table 5. The two most common and successful technologies are recycling of harvested rainwater in irrigation systems and rainwater harvesting for domestic rural water supply purposes. Technologies that are related to domestic rural water supply are shown in Table 6. Important issues related to the technologies are also summarized.
