The project’s main challenge was the diversion of the underground services in order for the excavation and construction of the 3-km-long canal to proceed smoothly. Cutting through high profile residential areas, as well as some of the city’s main traffic arteries, our teams went to great lengths to minimize the impact on the day-to-day traffic and the wellbeing of the local res-idents. Rethinking old methods, the new deep sewerage system was built using the NDRC method (non-destructive road crossings – directional drilling – micro-tunneling), pushing concrete GRP pipes over distances of over 100 meters, also limiting the impact on the surrounding traffic and neighborhoods. A remarkable strategy, as this method is usually put into practice to cross a single road, highway or railway.
