*The greatest achievement of Sanimet in the field of microtunneling was the construction of the "Vistula Collector - stage II and III" DN3200/3800mm in Warsaw. This collector is the largest microtunnel in Europe of total length 6,5 km long. This project was a technical and logistical challenge for Sanimet. The construction of the collector required specialist knowledge and experience in the construction of large-diameter microtunnels. In addition, the works had to be carried out in urban conditions, which required ensuring safety and minimizing the impact of works on the environment.
