What is so special in Markonahalli Dam?

 The technology behind these siphons is simple. Siphons are the only way for water to pass through. And these work on the simple principle of airflow. The air hole shown in the picture is always closed and when the dam reaches its capacity water is forced to pass through the siphons since there is no way for air to enter except the closed-hole!! Hence this dam requires no actual maintenance!! It takes very less time to empty the full dam (less than 2 hours!).
