KWT adjustable weir KSOS is a very simple yet effective way of penning water. It is essentially an aluminium frame with HDPE guides, holding aluminium boards of different height that can be stacked as desired. It’s minimum overflow is 50 mm. Those boards not in use can be kept within the unit, but above the water level, for later use. The top frame member is lockable, thus preventing unauthorized removal of the aluminium boards.
For larger constructions we have other solutions: Tijdelijke droogzet voorzieningen
