Assessing the asset condition according structural and functional criteria is the basis for further maintenance planning activities.

  1. Analyses of system functions of water supply and sanitary sewer systems are done on the basis of hydraulic modelling analyses.

  2. Analyses of structural conditions and condition assessments of sanitary sewer systems are based on TV-inspections.

  3. Analysis of structural conditions of water distribution systems are normally done indirectly on the basis of the failure documentation and water loss performance indicators.

  4. Asset condition data are recorded in a data base and accordingly in a digital network cadaster and are thereby available for further planning.
