Northern Sewer 87

As the audio begins, the sound of trickling water can be heard, echoing off the cold, hard walls of a pipe. This is the Northern Sewer 87, a vast network of underground tunnels that transport wastewater from bathrooms throughout the region. The constant drip-drip-drip of water is a testament to the ceaseless flow of this system. You can almost picture the labyrinth of pipes, dark and damp, winding their way beneath the city. Suddenly, a gush of water sounds, rushing through the sewer like a torrent, a reminder of the immense volume of water this system manages every second of every day. The audio takes you on an unseen journey of this crucial, yet often overlooked, part of our urban infrastructure.
