The realisation of sustainable urban development is one of today’s main challenges for local governments.
Facing grave infrastructural prob-lems that occur from unplanned growth of urban areas, local authori-ties need a broad and integrated de-velopment plan that allows planned interventions. But planning and the following interventions can’t be car-ried out without the availability and integration of current data from the concerned area. Many local govern-ments suffer from the inability to act, caused by:
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.
