Water is stored in the Vottigedda reservoir with a gross capacity of 27.13 MCM and a net capacity of 25.15 MCM.
The Project is contemplated for providing irrigation facilities to an extent of 16,670 acres covering 38 villages. The canal system consists of 2 main channels that is Right Main Canal covering 13,310 acres in between Vottigedda River and Nagavali River and Eastern Ghats in G.M.Valasa mandal and Kurupam mandal and Garubilli mandal.
