The contract involves building a 505-kilometre-long, 24-inch-diameter pipeline, a pumping station at Hassi R’Mel, a pressure regulator at Sougueur near Tiaret, a metering terminal at Arzew and 200 kilometres of fibre-optic cables.

The pipeline, known as LZ2, will link up with Arzew’s two main LPG complexes - GL1Z and GL2Z - and over time will replace the existing pipeline, LZ1. The project is part of the efforts of state energy company Sonatrach to improve the safety and security of its infrastructure.
