Project Description

Release holes, closable

Control the discharge flow of clean water.

To avoid surface pollution overflowing, a stable height must be maintained upstream of the dam.
Open the required number of release holes at the foot of the dam in order to maintain a stable level.
It is possible to open and close the release holes during use by simply applying pressure to the hatch.
