-------------------------------------------------------------------
Short description of measure
Problem to be solved: Flooding, droughts
Goal, potential objective: Preservation of functional ability in extreme weather situations
Developmental steps: Detecting problematic parts in the sewage network; plan for dynamic control of sewage system; unhinge precipitation from the sewage network or build up own system for precipitation
Instruments, implementation mechanism: Examination of rating mechanisms; close monitoring of discharges in waters and groundwater reservoirs; intelligent network control
Area of implementation: Urban
Responsibilities: Local wastewater company together with local environmental agency
Time horizon: Medium term
Economic aspects: Reduction of costs for complex irrigation; prevention of flood damage; general health
Promoters, obstacles, risks: High investment costs into existing plants must be written off; only limited effectiveness for flooding events
Side effects: Stabilisation of water balance; reducing costs for handling precipitation in the municipal sewage plant
Bridge to mitigation: Minimising the costs for transmission security; minimising decentral degradation of carbon materials and thus increase the possibility to use the greenhouse gases in a central energy of heating plant
