Tap Water

A Vital Resource Under Threat

We all drink too little tap water - even though in Germany and France it is considered the safest food of all. Here, as there, it is at least as good as bottled water from the supermarket. How can we make tap water more palatable (schmackhaft) to people? And: How is tap water actually produced? More...

Working Well With Waste Water

WWTP; WasteWaterTreatmentPlant

 

The WWTP treatment plan is executed in 3 steps. Each of these steps is crucial for clean water. 

Step I) is to get rid of fats or oils by using a "pre-treatment".

Step II) is responsible for biological treatment of organic particles in the waste water. In order to do so, the plant has to work through several technically hight maintenance processes. 

Step III) During the biological process, a mixture of bacteria creates some sort of "dirt" (Schlamm). This dirt is being removed in a different pool of the plant. 

 

The Waste Water Treatment Plant in Wolfhausen is about as big as 2/3 of a football field. Since there is another one in Bubikon which is the same district (Gemeinde), which means it covers an area of about 3500 people.
