This project is necessary to convey raw waters from the Mantaro river basin to the Marca III system and then to the Santa Eulalia river basin. It will transfer water from the Huascacocha lagoon to the Rimac river. The owner is the Ministry of housing, construction and sewage. The project includes a 3 km tunnel, 2.5 m wide and 3.5 m high (the upper part features a 1.25 m radius). The geology is volcanic rock of the Calipuy formation. This is an integral project tender, which means that each bidder is free to define a different tunnel route which would imply a shorter or longer length and different conditions for the tunnel.
