Godavari River is a major waterway in central India. The upper waters of the Godavari are scarcely utilized for irrigation, but the entire delta has been turned into a garden of perennial crops by means of the anicut at Dowalaiswaram, constructed by Sir Arthur Cotton 145 years ago.

The river enters the Andhra Pradesh near Bhadrachalam and flows touching the towns such as Godhavarikhani, Rajahmundry, Kovvur, Tallapudi and Narsapur in a southeast direction until it empties into the Bay of Bengal through two mouths. Whenever the discharge in river Godavari exceeds 28,320 Cumecs the water level in the river raises above the adjoining lands in the delta, affecting crop in 4.0 lakh hectares of rich cultivable land as also affecting the livelihood of 3.5 million people. Based on the experience of past floods, it was proposed to raise the flood banks by 2.00 m over the observed maximum flood level (OMFL) of 1986 flood and widen the banks to the standards for the length of 405.50 Kms.

Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) was launched for enhancing physical access of water on farm and expanding cultivable area under assured irrigation, improve on-farm water use efficiency, introducing sustainable water conservation practices. Under this scheme, 99 ongoing AIBP funded irrigation projects have been identified for prioritised implementation in mission mode along with their Command Area Development (CAD) works. The Cabinet Committee on Economic Affairs has approved that CAD works of 99 prioritised AIBP projects are to be funded through NABARD borrowing under long term irrigation fund under existing CADWM programme. Eight irrigation projects of Andhra Pradesh were listed under prioritised ongoing AIBP funded irrigation projects. ConTec was entrusted with the work for preparation of DPR for three projects. Geospatial survey for a Command Area of over 80,000 acres was conducted by utilising a combination of Satellite DEM and UAV Photogrammetric survey, for preparation of DPR for undertaking CADWM works of KOR Gundlakamma reservoir project.
