The ancient sewer systems of the Pompeii are in such good condition that the current authorities want to start using them again. Some tunnels – about 450 meters long – have already been evaluated by specialists.
Interestingly, the rest of the tunnels are currently being tested and if it is also positive, then the sewage system will certainly be used.
In ancient times, these tunnels were designed to drain water from the center of Pompeii.
