KWT KKS-PE tilting weirs placed in Germany
Project Hamburg – Owner: BUKEA or “Behörde für Umwelt, Klima, Energie und Agrarwirtschaft”.
At this project location we can find compensation areas – usually suited for various different flora and fauna – in the form of structurally rich grasslands containing numerous ditches that hold water all year round. Depending on the availability of the site’s other external water sources, such as the side arms of the Elbe, Dove-Elbe, Gose-Elbe or other larger drainage ditches, our tilting weirs have different functions. Even without additional external water sources, they will guarantee more water retention during periods of heavy rain and for seasonal water level adjustments. Additionally they are now able to keep their water on-site. In comparison to a conventional overflow weir our tilting weirs have offered many advantages for BUKEA. In consultation with the local farmers regarding their needs – being that manageability must be guaranteed – the diverse water levels are now regulated with more precision then before. Additionally, the general high durability of our tilting weirs in combination with their partial motorization has proven to be very efficient for our client for their goal of maximizing the efficiency on this site.
When the site receives more water from an external water supply like for example the Allermöher Wiesen, the tilting weirs make it possible to implement a management method through means of “terraced damming”. Since this management method can clearly be seen from the air, this can send clear signals to the local bird population in regard to their migrations. Not only in regard to the wildlife, but also for the preservation of the flora, the local water levels can be more precisely adjusted to the specific demands of the terrain. This ensures that these areas can be continuously managed during the whole year, which leads to less damage to the turf and allows more efficient cultivation. This is of course in addition to the function of allowing swift an precise adjustments during any extreme or generally heavy rain in order to direct any excess water to other regions.
