Innovative procedure for improving water quality at the Fennsee
renovation of the Fennsee shows positive effects on water quality
The Charlottenburg-Wilmersdorf district office has successfully initiated innovative measures to improve water quality in the eastern part of the Fennsee. The use of a new procedure should not only significantly increase the water quality, but also effectively reduce odor nuisance by lazy gases.
The Fennsee suffers from the effects of harmful substances that get into the lake through rainwater from streets and sidewalks. Especially in heavy rain, leaves and dirt get into the lake via the rainwater sewage system, where they are decomposed by microorganisms. This decomposition process leads to high oxygen consumption, which in turn leads to the formation of foul gases. These gases often cause unpleasant smells in the vicinity of the lake in summer and can also endanger the survival of fish.
In order to counteract this problem, the district office has installed a special system with ventilation, measuring devices and a dosing station. This system continuously monitors and regulates the oxygen content in the lake in order to be able to react flexibly to weather changes. Thanks to these measures, no smell problems could be determined this summer despite numerous heavy rain events.
The environmental city councilor Oliver Schruoffeneger is pleased with the positive developments: "The measures have already led to a noticeable improvement in the situation. The Fennsee was a problem child in the area of water protection in the district for a long time. We are increasingly orienting our work on the requirements of the climate adjustment and have achieved significant progress with the climate adjustment concept. Nevertheless Water protection at limits.
