scope:
This standard gives directions for the inspection of sewers and the conversion of the inspection results to maintenance urgency and repair or replacement urgency. The connected pipes are explicity excluded because their ownership and control does not always correspond to the ownership and control of the rest of the drainage and sewerage systems. The directions are intended to serve as a guide for the inspection of sewers and for the interpretation of the results.
