gis based sewer maintenance using mapwindow open source gis
DESCRIPTION
Sewer maintenance workers are sensors for a lot of sewer specific phenomena like sedimentary depositions, smell, damage, danger, amount of work and best practice. The knowledge of these factors is important for optimized rehabilitation and maintenance concepts. Sewer maintenance workers put their data into a GIS based tool and they get back information about sewers which have to be maintained next. Subsequently the data are used in hydrodynamic and prognosis models to include operational experience in the planning processes of an optimized long term sewer rehabilitation. In Graz the sewers are now GIS based maintained. The long term strategy is to get low-maintenance sewers to be able to increase the maintenance quality followed by an increase of the lines span of life.

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

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
