Between July and October 2017 excavations and works were conducted on Queen Shlomzion Street in Tel Aviv. As part of these works, new sewage lines were installed so we were able to follow the complex system that the sewage cover is its "tip of the iceberg".
Here is a set of pictures along the timeline from the beginning of the works until the final result.

Before tarring, the system is completely immersed and only the covers are visible
