Abstract
Purpose
This paper aims to investigate the condition and select a repair procedure for a damaged sewer in Kharkiv, Ukraine.
Design/methodology/approach
Inspection shafts are critical objects in the sewerage networks and are exposed to the strong influence of destructive processes, which are mainly corrosion of concrete structures, penetration of surface water inside structures, static and dynamic loads generated by truck transport, deviations from the codes and errors in construction, poor quality of the shaft wall surface, aggressive biological environment and ground subsidence. Therefore, selecting the optimum repair technology is of current interest.
Findings
The problems of repair and refurbishment of inspection shafts in deep-level sewer tunnels were considered. The technical and technological solutions using profiled polyethylene, reinforced slag cast panels, ceramic bricks and protective coatings are given. The advantages and disadvantages of the proposed technologies and examples of their practical application are shown.
Originality/value
This study performs reconstruction and strengthening work for a damaged section of the inspection shaft without shutdown.

Abstract
Purpose
The purpose of this study to monitor the state of deep sewerage networks is a task of current interest in connection with the emergency and pre-emergency condition of a large part of sewerage systems in the cities of Ukraine.
Design/methodology/approach
To monitor the state, performance and reliability of deep sewer collectors, it is necessary to provide monitoring wells and, during the lifetime, to carry out planned inspection of groundwater levels in the wells and to timely identify areas of filtration of wastewater into the ground.
Findings
Monitoring the state of deep sewerage networks is a task of current interest in connection with the emergency and pre-emergency condition of a large part of sewerage systems in the cities of Ukraine. To monitor the state, performance and reliability of deep sewer collectors, it is necessary to provide monitoring wells, and during the lifetime, to carry out planned inspection of groundwater levels in the wells and to timely identify areas of filtration of wastewater into the ground.
Originality/value
Implementation of works on reconstruction and strengthening an emergency section will extend the service life of the sewer collector without reducing its capacity.
