SEWER MAINTENANCE• Bild Spülfahrzeug
INGENIEURBÜRO DIPL.-ING. WERNER SPRUNG MWCONFERENCE 2014 4
FORMER PRACTICE• Bild Tafeln Betrieb Abwasser
INGENIEURBÜRO DIPL.-ING. WERNER SPRUNG MWCONFERENCE 2014 5
WHY CHANGE THE FORMER PRACTICE?• Objection: Increasing the sewers live span
• Method: Calculate dynamic maintenance intervals by a damage forecast model
• Material: Maintenance data are needed a GIS based application is installed

PRACTICE
INGENIEURBÜRO DIPL.-ING. WERNER SPRUNG MWCONFERENCE 2014 22
OPTIMIZATION TOOLIt includes:
•Work reports
•Operational requirements
•Hydrological requirements
•Company requirements
INGENIEURBÜRO DIPL.-ING. WERNER SPRUNG MWCONFERENCE 2014 23
BENEFIT• Maintenance dependent on requirements
• Information for planning about sand and gravel deposits in sewers
• Information for planning about operational time and effort for each conduit
• Master data list for each conduit
• Effective work report

CONCLUSION
• MapWindow based applications help to optimize sewer maintenance. Those tools increase the sewers live span and reduce the pollution in our rivers.
