■Achieves stable water intake from the entire thickness of the aquifer throughout the year. It is used to take water from unconfined aquifers (underground water/free water) and takes water from relatively shallow underground locations. Stable water intake is possible even when the water level drops during droughts. ■POINT ・Water intake from the entire thickness of the aquifer ・There is little water level drop compared to the amount of water intake, and water intake efficiency is high. ・High-pressure cleaning possible from the inside ・Aperture ratio of 30% to 50% or more is possible ・Inflow velocity Very slow flow velocity 1.0cm/sec or less
