Repair of 12 DN150 diameter house connections in a densely built-up area of the 19th century. The work was carried out without access to the basements of residential buildings, without excavation in the surrounding areas and without coordination with residents. SP!RES technology/RES allowed to restore the tightness of the pipelines, preserving the historical infrastructure of the city.

The first stage was a TV inspection of all 12 issues. This made it possible to accurately determine the damage sites, pipe diameters and the length of the areas requiring rehabilitation. At the same time, the pipes were hydrodynamically cleaned of deposits.
