Sewage plants are good and important, but the system has its limits
The German
water infrastructure and its tap water quality belong to the best of the world.
Also its quality standards for drinking waters are excellent. Nevertheless, the
centralistic flow-through concept sewerage/sewage plant reaches its limitations
again and again.
In the case
of heavy rain falls pathogens and nutrients are flushed into our environment. Pharmaceuticals
and endocrine substances are a permanent problem. The hospitals are a
particularly explosive topic. There is an urgent need for action.
Whether
treated in sewage plants, or not – pathogens, hormones, resistance plasmids and
pharmaceuticals are thereby released into our water resources, causing serious
threats to our environments and public health. In many countries of the world,
this shortcut between toilets and drinking water faucets exists. Moreover, the
nutrients incorporated by humans and excreted with urine can thus only poorly
be recovered.
