Haneji Dam

Construction on the river diversion tunnels commenced in 1993 and work on the dam's body began in 1998.

[1] The dam and its facilities are equipped with several innovations to improve water quality and the environment.

Water discharged from the dam powers two small turbines which provide electricity for the operation of shallow and deep aerators.

An airlift system was developed which transfers fish through tubes in and out of the reservoir.

The radial gate that controls the intake was split and reversed in design.
