Material1: River Surface Water Intake Method

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

The "river surface water intake method" involves creating a separate waterway in the river's flow, installing a surface water intake valve at the flow center, and allowing impurities and debris to flow away while only taking in clean surface water. This method enables the use of river water, which is now considered equivalent in quality to well water, traditionally deemed optimal for water intake. The river surface water intake method can prevent environmental destruction, 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 taken state without concerns about environmental pollution. Furthermore, it resolves issues that could cause pump failures due to debris. 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 the higher temperatures of surface water.
