European Heritage Days - Visit to the Colmar wastewater treatment plant

On Saturday 20 September, come and discover the wastewater treatment process at the Colmar wastewater treatment plant: an essential facility for protecting the environment!
Showering, washing dishes, flushing the toilet... these are all everyday activities that require water.
Once used, this dirty water, known as wastewater, is transported to the Colmar treatment plant
to be cleaned through various stages that transform it into clean water before it is returned to nature!
