| Short description: |
Within the European project APUSS (Assessing infiltration and exfiltration on the
performance of urban sewer systems) a model describing the ex- and infiltration process
will be developed. Therefore sewer classification by leakage is required. A main input to
this classification is the structural deterioration of sewer pipes observed by closedcircuit-
television (CCTV). This paper proposes a new classification system, which
evaluates the leakage of sewers based on existing CCTV records. The classification is
focused on the assessment of defects that cause a potential leakage. The condition classes
obtained can be compared with the pipe characteristics from sewer databases and with
ex- and infiltration rates. The comparison is a subsequent step in the modelling process.
