Contract Management and Related Works for Construction of Sunkoshi Marin Diversion Multipurpose Project

Irrigation Project

The work involves design review, construction supervision, quality control, project management, construction and contract management. The project aims at producing hydropower and providing irrigation facility in the southern plains of Province 2. The project plan includes construction of barrage across the Sunkoshi River to divert 67 Cumecs water through a 13.1 km concrete lined tunnel to be constructed by using a Tunnel Boring Machine (TBM) followed by a surface powerhouse positioned on the Marin River in Kusumtar of Kamalamai Municipality, Sindhuli District. The diverted water along with available head between the intake and powerhouse will be utilized to produce 28.62 MW hydropower. The water downstream of the tailrace flows through the Marin River down to Bagmati river. The discharge of Bagmati River will be augmented by a more or less constant quantity diverted from Sunkoshi River which will facilitate a year-round irrigation in about 122,000 hectares of irrigable land in Bara, Rautahat, Sarlahi, Mahottari and Dhanusa districts including existing command area of Bagmati Irrigation Project.
