One of India’s greatest water transfer systems was carried out using Tunnel Boring Machines beneath the Nagarjuna Sagar National Park, the country’s largest tiger sanctuary. In order to complete Tunnel 2 of the Poola Subbaiah Veligonda Project, Rithwik Projects has deployed Robbins Double Shield TBM. The potential inlet site for the P S Veligonda Project is located on the Krishna River, on the right bank of the Srisailam Canal. The system is designed to carry nearly 1.2 billion cubic meters (317.0 billion gallons) of flood water from the Srisailam Reservoir’s shore. Water will be delivered to more than 3,95,368 acres of farmland across Prakasam, Nellore, and Kadapa districts via two parallel tunnels that are 19.2 km long each. The bored tunnels will carry water at speeds of up to 243 cubic meters per second (64,193 gallons per second) to a feeder canal.
