Survey to be undertaken for project
Highly advanced LIDAR (Light Detection and Ranging) Survey will be taken up by Water and Power Consultancy Services (India) Limited (WAPCOS) to prepare a Detailed Project Report (DPR) for supplying Godavari water directly to Rayalaseema.

After successful linkage between the Godavari and Krishna rivers through the Pattiseema project, now the government is embarking on linking the Godavari with the Penna.

What is (LIDAR) Light Detection and Ranging survey?
Lidar (also called LIDAR , LiDAR , and LADAR ) is a surveying method that measures distance to a target by illuminating that target with a laser light.

Where is this method used? 
Lidar is popularly used to make high-resolution maps, with applications in archaeology, geography , geology, geomorphology , seismology , forestry , atmospheric physics ,area guidance , airborne laser swath mapping (ALSM), and laser altimetry. Lidar sometimes is called laser scanning and 3D scanning , with terrestrial, airborne, and mobile applications.

About the project 
The project envisages transporting 20 tmcft from Godavari River to two reservoirs – the existing Somasila Reservoir in the Penna river basin and a new reservoir at Bollapalli.
