Map with all coordinates: The Túnel Emisor Oriente is a 63 km long sewage tunnel under construction in Mexico . It leads from Mexico City to the northeast in the state of Hidalgo and is intended to discharge a maximum of 150 m 3 · s −1 of wastewater.
Mexico City was built on the drained Lake Texcoco . In the past 100 years the city has sunk by up to 12 m due to the extraction of groundwater. The main sewage collector "Emisor Central", built in 1975, and the "Gran Canal" from 1900 lose a gradient due to the sinking, which means that they no longer achieve their originally planned capacity.
construction
The Túnel Emisor Oriente has an internal diameter of 7 m and is driven with three tunnel boring machines from Herrenknecht with a shield diameter of 8.7 and 8.89 m. The construction time was originally estimated at five years, but the changing subsoil delayed progress. A tunnel boring machine was damaged when it hit flat stone slabs.
