The Periyar valley Irrigation project in Ernakulam district envisages the utilization of the tail race discharge from the completed Hydel scheme in the Muthirapuzha tributary of river Periyar together with the controlled release from Ennackal dam constructed by Kerala State Electricity Board under Hydel scheme across the Idamalayar tributary and the dependable run off from the uncontrolled catchment of Periyar river, for irrigating an area of 32.80 Th ha (CCA) of land lying on the left bank of Periyar river through a net work of canal system and controlling devices. The above project helps in stabilization of first and second crops in an area of 32.80 Th ha and raising an additional crop in an area of 20.0 Th ha of 3rd crop (Puncha). Thus the gross potential ayacut of the scheme will be 85.60 Th ha and is spread over in Kothamangalam, Muvattupuzha , Kunnathunadu, Aluva, Kanayannoor and Parur Taluk in Ernakulam district.
Apart from irrigation on left bank of Periyar, the project also enables supply of minimum quantity of water through the river to check the intrusion of salinity at lower reaches as well as to meet the requirements of many lift irrigation schemes of river Periyar. Supply of water for drinking purpose, industrial purpose etc. will be met through storage by the barrage of Bhoothathankettu.
