TEP Tunel Emisor Poniente project, with a length of 5.9 km and external diameter of 8.7m (internal diameter:7m), is a key component in a massive wastewater overhaul that will put end to serious groundwater problems in the region. Indeed, due to extensive settlement of subsoil, existing sewage systems lose their capacities. Further, heavy rainfall regularly causes severe floods.
