Wastewater discharged from house- holds and SME to the surface water, as well as un-proper designed septic tanks are a significant source of wa- ter pollution. This urban problem can only be solved if the locations of wastewater generation and dis- charge are known. The assessment of qualified and quantified data, their centralized availability, integration and combination are basic pre-con- ditions for all planning processes.
