• Construction of a 4,100 meter sewage tunnel with an internal diameter of 1,600mm, carried out through pipe jacking.
• Installation of a 1,000mm polyethylene pipe for 100 meters, at a depth of 8 meters, using a horizontal drilling method.
• Installation of a 400mm polyethylene pipe for 211 meters, at a depth of 8 meters, using an open excavation method.
