ResumoRegarding the average age of sewers in Austria, rehabilitation becomes more and more important. In Austria so far no guideline for sewer maintenance and rehabilitation strategies exists. The paper reports about the preparation for developing a guideline to raise the working quality of several branches involved in sewer maintenance like e. g. high pressure jetting, CCTV-inspection together with the development of standardised tender documents. A Pilot-Study was financed by the ministry of environment and the regional government of Styria to develop in several theoretical workshops and practical implementations a guideline for sewer operation and maintenance. With 4 operators the project has been carried out to test the proposed instructions described in the guideline which will be revised for an Austrian-wide application.
