With a resulting increase of water intake from 8.3 m3/s to 23.65 m3/s a water treatment plant and upgraded Phase II hydroelectric power plant were also erected. The original Phase I power station was decommissioned, but with the commissioning of the Phase II power station and two additional sub stations, overall generation capacity from the Lake Biwa Canal rose to 6,400 kW by May 1914.
As a result, water consumption surged from 8.3 m3/s to 23.65 m3/s, prompting the construction of a new water treatment plant and an upgraded Phase II hydroelectric power station. The old Phase I power station was shut down, but with the launch of the Phase II power station and two additional substations, total electricity output at the Lake Biwa Canal rose to 6,400 kW by May 1914.
