The Emisor Oriente Tunnel, also known as the Tunel Emisor Oriente, Eastern Discharge Tunnel, Eastern Wastewater Tunnel, and East Issuing Tunnel, is a wastewater treatment tunnel in Mexico City, Mexico.[1][2] At 62,500 m (38.8 mi), it is the seventh longest tunnel on Earth. It was constructed between 2008 and 2014 using a tunnel boring machine. Serving a population of 20 million, it runs from Mexico city to the Atotonilco Wastewater Treatment Plant in Hidalgo state. It runs at a maximum depth of 200 metres below ground level and has a discharge capacity of 150 m3/s. This tunnel will help prevent flooding and serves as an alternate exit for the Emisor Central, another drainage tunnel.

In order to prevent collapse, the tunnel is constructed using a lining with segmental rings made of concrete and steel.

The estimated cost for the tunnel was 15 billion pesos.
