Have you ever thought of the possibility of a dam disaster and the magnitude of its aftereffects? Will you believe that a dam disaster can kill more people and can cause more causalities and after effects than that of Hiroshima and Nagasaki incident? Yes, if we do not give much attention to this issue, which is looming over the millions of lives all over the world, it will bring out catastrophic consequences for humanity.

In 1975, China witnessed the greatest manmade disaster that caused the death of more number of people than in any other manmade disaster happened across the world so far. At the beginning of August, there occurred a typhoon because of the change in the weather pattern. When the hot, humid air of the typhoon met the cold air of the North, series of storms and rain occurred. The first one was on August 5, followed by the second one on August 6th and the third one on August 7th. The dam was designed to store 300mm of water per day. During these days within 24 hours itself more than one year's rain was poured. Banqiao and Shimantan dams were filled by August 8th and were in the urge to burst. On August 8th 12:30 am, Shimantan dam collapsed followed by the collapse of Banqiao dam by 1:00am on the same day. Totally 62 dams broke, affecting the life of eleven million people. Even the evacuation orders failed to reach many people because of the problem in communication caused by flood. People who survived in this flood were trapped without food. Contaminated water affected the health of several people. These dams were built by foreseeing the flood that may occur, but even then, the natural calamity was of that high level and the dams failed to hold the tempestuous water rained down. To prevent more disasters they even destroyed several small dams so that the water would flow to the areas with less population.

These dams, which collapsed mainly, affected the local population. According to the records nearly 26,000 people died because of flood and nearly 145,000 people died because of famine and epidemics. Nearly 5,960,000 buildings collapsed and 11 million residents were affected. Many were injured. This converted China into a land full of corpses.

Sohan Roy wrote the script of DAM999 by being inspired by the Banqiao dam disaster in China. He wanted people to know the real after effects that a dam disaster can cause. Through DAM999, he warns the entire world about this manmade disaster that could devastate the existence of human race on the earth.
