There is a location near Petersburg where some heat supply utilidors and book ducts and sewers are neighboring. In one beautiful day three explorers, Lucy, Lanivs and Mutabor had decided to visit them. They were succeed in visiting two utilidors and a brook duct under the railway (pic 1–13). Some pictures Lanivs had made using film camera (pic 14–16). And some time ago Mutabor had visited this place again and also had made some shots (pic 17–19).
We know that Brachnev brook in addition to some short ducts also passes through a relatively long (about 300 meters) concrete sewer. And in one summer day Mutabor has explored this sewer (pic 20–32). He also had made a picture of the duct passing under the subway depot (pic 33) and the inlet of the small duct under the railway (pic 34).
Icicles
Once Mutabor has visited the sewer of Brachnev brook in winter and found out that there are many beatiful icicles and ice incrustations inside (pic 35–41)
