Taizi Central School is situated in the Qinghai’s Huzhu County, a region that is remote, mountainous, arid and cold.  The school's original dry toilets suffer from inadequate facilities, lack of proper sewage systems, and ineffective disposal of waste. In summer, a pervasive odor fills the air, while in winter, the freezing temperatures make the ground hard and icy. This compromises the convenience and safety of students using the facilities. Moreover, the dry toilets offer limited handwashing opportunities, hindering students to cultivate good hygiene behaviors.

UNICEF, in conjunction with China’s Ministry of Agriculture and Rural Affairs (MARA), constructed climate-resilient Micro-water-flushing Sanitation Facility that utilized a combination of energy- and water-saving technologies. The designed water-saving water cistern uses only less than half the amount of water compared with that required by standard toilets.  Leveraging the ample sunshine hours in Qinghai, solar energy is utilized for the heating of the toilets, while incorporating polyurethane insulation in the walls to minimize energy consumption and carbon emissions. The sewage treatment system ensures that wastewater from the toilets meets the standards before discharge. Additionally, a rainwater and hand-washing water harvesting system provides the water for campus greening, promoting water resource conservation.

After the construction of the new toilets, there has been a remarkable improvement in the sanitary conditions, am enhancement in the ease of access for students, and a decrease in the risk of disease. Moreover, it is reshaping students' personal hygiene behaviors.
