The work is focused on characterization of selected physical properties of sewage sand from the waste water treatment plants. Sand is transported into wastewater mainly in areas with a combined se­we­ra­ge system – principally in connection with rainfalls, in case of which it is transported through the sewerage system together with rainwater, but also (within smaller extents) due to leakages of sewerage systems or bad conduct of natural persons and legal entities. The main attention was focused on basic physical parameters such as content of total solid, ash free dry mass, density and granulometry. These material parameters are very often underestimated so the set of quality data is completly missing, as well as a background for designers of wastewater treatment plants. This paper should be quite useful e.g. for the purpose of technological equipment design in the region of South Moravia.
