Dan Region National Sewage Project
This project was part of the Dan Region Association for Environmental Infrastructure National Sewage Project. For the first time in Israel, a vacuum sewer of this cylinder and material was constructed, 22 kilometers in length and 125-150 centimeters in cylinder. From Petah-Tikva in the north to Rishon-Lezion in the south, its tunnels were constructed using the tunnel jacking and dig-and-cover methods. Project cost was approximately NIS 650 million ($2,275 million).
