Exterior water level < Interior water level

- When exterior water level drops lower than that of interior water, pump gate® will be opened so that gravity flow will discharge in interior water toward outside.

- No structure being required, it is recommended to put in a very populated city area.





Exterior water level > Interior water level

- When exterior water level goes higher than that of interior water, hinged pump gate® will be completely closed so that prevention of exterior water enters into the interior water through gate.

- If interior water level reaches to the pre-determined water level, pump and screen will be automatically operated in order to forcibly discharge interior water toward outside.

- When exterior water level is lower than that of interior water, pump gate® opened so that gravity flow will discharge interior water toward outside.
