Operational monitoring of the technical condition of reinforced concrete structures (wells, collectors, tanks) in wastewater disposal systems is a set of periodic measures aimed at the timely detection of defects and the prevention of accidents. Its particular importance arises from the structures' operation in an aggressive environment exposed to moisture, temperature fluctuations, stray currents, and mechanical loads. The objectives of operational monitoring include the identification of visible and hidden defects (cracks, chips, delamination of the protective concrete layer, exposed and corroded reinforcement, leaks in joints, and mutual displacement of precast elements), an assessment of the strength and deformation properties of materials (concrete and reinforcement), the degree of corrosion, checking the tightness of the structures, and verifying the compliance of actual parameters with design specifications. Monitoring is implemented using visual and instrumental non-destructive methods, ensuring rapid results. Based on the monitoring results, a report is prepared with measurement protocols, defect diagrams, and recommendations for repair or reinforcement of the structure. Operational monitoring is planned and preventative in nature. According to current regulations, the recommended frequency is at least once a year, and more frequently for facilities showing signs of deformation or in a state of emergency. One of the modern innovative approaches that is beginning to be adopted globally is the digitalization of processes related to the operational monitoring of the technical condition of wastewater disposal systems. However, the implementation of digitalization requires both the development of new regulations and the development of an information infrastructure (systems and specialized equipment for diagnostics in difficult operating conditions, specialized software, etc.). Therefore, systematic operational monitoring using an integrated approach based on both visual and instrumental methods, including the use of digital systems, is a prerequisite for maintaining the operability of wastewater disposal systems. This will enable a transition from repairs following an accident to preventive technical condition management, significantly increasing the reliability and extending the service life of utility networks.
