Mission Possible Cambodia School is located at Takeo province of Cambodia, housing 600 children in poverty and the only primary and secondary school in the village. After 10 years operation of the school, there are flooding and electrical engineering challenges. The flooding during the wet season between June and September affects the operation of school. Children needs to walk through the muddy and sometimes flooding area from entrance gate to the school campus. Mission Possible-Hong Kong and EWB-HK are dedicated to alleviate the flooding situation by proposed drainage on the onset of upcoming wet season in May and then improve electrical system to reduce potential hazard.
