CHARACTERISTICS OF THE RESERVOIR
- An underground reservoir 26 metres deep and 40 metres in diameter, with a circular diaphragm wall, a concrete apron resting on 170 micro-piles, tie plates and an abutment slab in prefabricated sections (beams and plates).
- Constructions inside the reservoir: slope forms, trough support shells, two vortex wells, a concrete spiral staircase, upper and lower steel walkways.
- Technical premises under the stadium: civil engineering and finishing of the premises for ventilation, electricity, toilets and washrooms, access gallery and outlet tunnel.
- Start well for the micro tunnel borer at a depth of 12 metres to connect the reservoir to the storm spillways.
Work was completed at the end of December 2017.
