An old wooden pipe

An old,destroyed waterpipe The following two slides show how our water work works:

I Rain water filtrates into the ground and builds the ground-water table II It is collected in an 18 metres deep well III From this well it is pumped up to our waterwork in the wineyards above Kenzingen where it is collected in two enormous tanks IV From these tanks water goes back to town into the households and fountains V Because of the difference of altitude and the pressure resulting from it no pumping is necessary for this step VI Water in Kenzingen is rather hard but it is so clean that it doesn‘t need any treatment

Sewage waste water in Germany

•Our waste water runs into pipes in the ground •From there it goes into a waste water treatment Sewage water in Freiburg

•The industrie contaminated the Dreisam and other small rivers. •In the city centre were small rivers in which the people put their rubbish and the excrement •The farmers took out the excrement for money •During the summer the Dreisam hadn't got so much water and so it could not take off all the exrement and the rubbish •The people had to build a waste water treatment – information

The straightening began in 1817 and finished in 1876  Intended by Johann Gottfried Tulla  Construction of one direct riverbed  Destruction of many wetlands and other little rivers

One big river which you can use for voyage and transports

The biota was largely destroyed Rhine - Straightening Taubergießen

 One of the biggest nature protection areas in Baden-Württemberg

 10 km² of the land is owned by the French community Rhinau

 There aren't many minerals

 Constant temperature

 Nature protection area since 1979 There are 23 sorts of orchids in Taubergießen
