As one of the lowest-lying terrain in the Hulu Langat sub-district, the areas surrounding Kg. Sungai Serai is often hit with both river and flash floods.  As such, there was a necessity for the residents in this area to become familiar with early warning and public warning systems and know what to do once they receive the alerts.  This need culminated in the implementation of a Community Evacuation Drill, which is an exercise spearheaded by the community members with assistance from the government agencies.

The drill was conducted by the village leaders, community members, local disaster response NGOs, the Malaysian Civil Defence Force (APM) and the Selangor Disaster Management Unit (SDMU).
