Protection of groundwater resources is important for preserving drinking water, especially for karst aquifers which are particularly sensitive to pollution from sewage. The sewer system inspection and maintenance model for groundwater protection has been developed and it consists of three objective functions: regular maintenance, emergency maintenance and investment maintenance. Regular maintenance includes activities related to preventive maintenance, while emergency maintenance includes a variety of activities related to corrective maintenance. Investment maintenance deals with replacement, renovation or restoration of the sewer system. The model includes sewer maintenance, geodetic works, internal pipe inspection using CCTV, external inspection of the sewerage system and hydrodynamic flushing of the pipe network. The model was tested using data from the real system.
