Siphon systems are created to flush out the excess water. As per the dam official, this is Asia's first Siphon dam. This is a must visit place for civil/mechanical students for its engineering marvel. Here water is sucked into the pipe from the small openings due to air pressure difference and pushed into the well which is approximately 90 feet. One can see the turbine like structure inside through which the water flows. This is done to control the flow of water. When it crosses the danger mark, crest gate will be opened manually with the help of motor. In case of power problem they have a handle to open. As per the official, during monsoon season when the dam is full, this will look like the turbine is rotating. In reality, it is not the case. We were lucky to see this before the dam was full.
For food you need to travel approximately 2 km from this place. The first restaurant you see when you touch Bangalore Tumkur highway when returning to Bangalore is Adyar Ananda Bhavan.
