Material1: River surface water intake method

Creating a rich community of water and greenery. Introducing the "River Surface Water Intake Method" from Shiga Industrial.

The "river surface water intake method" refers to a system that establishes a separate waterway in the river's flow, installing a surface water intake valve at the flow center to allow the passage of impurities while only extracting clean surface water. This method enables the use of river water, making it equivalent to well water, which has traditionally been considered optimal for water quality. The river surface water intake method can prevent environmental degradation such as ground subsidence compared to groundwater use. Additionally, it has made water intake easier in mountainous areas where wells cannot be drilled. Since it uses natural water, it can be discharged in its extracted state without concerns about environmental pollution. Furthermore, it can also resolve issues such as pump failures caused by impurities. Currently, there are nine water intake facilities using this method established in Shiga Prefecture. Developed in collaboration with a company in Hiroshima for snowmelt facilities in areas with heavy snowfall, this method is also gaining attention as a suitable water intake method for rice cultivation due to its higher temperature as surface water.
