Massive improvement of municipal wastewater treatment during the last 20 years has reduced the pollution load of our water bodies significantly. At the same time, pollution load resulting from combined sewer overflows (CSO) increased which made appropriate countermeasures necessary. Up to now, this is usually done by introducing combined wastewater basins including sedimentation as a first treatment process which does not affect the soluble substances at all. The only technology that is capable of reducing settable compounds as well as soluble compounds is the plant covered retention soil filter (RSF). First full scale RSFs were built in Germany in the early 90ties within the scope of pilot projects. Today the pollution load caused by CSO becomes predominant in Germany and therefore RSF technology covering mechanical and biological CSO treatment gets more and more attractive. Thus, appropriate guidelines have to be elaborated or already existing guidelines have to be updated. The latter is one of the goals of a research project carried out by the Department of Environmental and Sanitary Engineering (DESE) of the University of Kassel covering building and operation of three new RSF in the Federal State of Hessia. Upon completion of the RSF building phase this paper summarises the most important features from the construction site, which easily can be mishandled.
