Under the WASH program, TSDO has conducted activities in Water, Sanitation, Hygiene, and Basic Preventive Health.

Water Reservoir: TSDO has focused on the collection, storage, and distribution of water through village water supply networks. This includes the development, improvement, and management of water storage facilities to ensure a reliable and safe water supply for the community. Reservoirs play a crucial role in these efforts, particularly in areas where water sources are seasonal or irregular, thereby promoting overall community well-being.
