What I did: I made the detailed design and supervision of the installation by microtunneling and HDD, in very hard and abrasive quartzite-diorite rock, of a DN700 mm (28″) cast iron water pressure pipe – the work was split in two section, each one 80 m (265 ft) long. The borehole diameter was 800 mm (32″). A very challenging job for the extreme hardness and abrasivity of the rock. The water pressure pipe is part of a mini hydro-power plant in the Alps (Italy).
