	Summary:
	With combined sewage systems (communal + storm water) retention and clarification of excess storm water is mandatory, since waste water treatment plants (WWTP) can't treat these water quantities in a proper way. Retention and clarification should be done before discharge to recipient. This waste water clarification system is composed of retention basin, whose purpose is removal of suspended and floating substance, and relief overflow. With application of retention basin with relief overflow, competent flow for dimensioning of the WWTP can be defined. In the same time, waste water discharge to recipient is also regulated with retention basin with relief overflow. Criteria for dimensioning of these objects are presented in German standard ATV-A 128. With application of German ATV-A 128 standard, hydraulic parameters for retention basin and relief overflow for Novi Sad are defined and tested in hydaulic model made with EPA SWMM 5.0 software. These parameters are valid only for combined sewage systems.
