In conventional water intake equipment installed over rivers and sluices, floating dirt and leaves as well as sand and gravel used to block up the water intake opening, requiring frequent cleaning. Large-scale power-driven dirt clearing equipment, on the other hand, is expensive.
We succeeded in developing innovative maintenance-free water intake equipment which removes floating dirt and leaves, eliminating the adverse effects of sand and gravel. In addition, since this new equipment harnesses naturally flowing water without using any auxiliary power, both the initial and the running costs can be reduced compared with conventional solutions.
Therefore, our movable weir with an intake screen is very versatile and can perform three differrent functions of lifting the weir, water intake and removing floating dirt and leaves.

従来から河川や水路の取水装置は、砂礫や浮遊物が取水口をふさぎ、頻繁な清掃が必要でした。また、動力を使う大掛かりな除塵装置は、コストが高くなる問題がありました。そこで当社は、砂礫の影響を受けず、浮遊物は動力を使用せずに流水の力で取り除く、トータルでの設備コストを抑えた、画期的なメンテナンスフリーの取水装置を開発しました。この可動堰スクリーン取水装置は、堰上げ、除塵、取水の３つの機能を１台に集約した製品です。
