This sewer is also well known among explorers from Petersburg. Some years ago sanitary sewer was directly put into the Murinsky brook (the name of the sewer "Mura" is derived from this name), and explorers can enjoy muddy water with poos and condoms. Now the main part of the sewer is partitioned by a wooden shutter (you can see it on our picture) and the rest part serves as a drain sewer. We have visited just this part.
