The project is part of the Bathing Safeguard Plan of the town of Rimini that is one of the most famous seaside resorts in Europe thanks to its 15-kilometre-long sandy beach, over 1,000 hotels, and thousands of bars, restaurants and discos. The plan includes structural interventions on the sewerage system with the primary purpose of reducing the number and frequency of the discharges of waste water in the sea during the rainfall events.
Main aim of the works is to reduce and modulate the discharge flows (actually discharged near the seashore) and move the output site far in the sea.
The project foresees the construction of a rainstorm and first flush retention tank in an important touristic area on the seashore of Rimini, thus requiring both a technical and architectural accurate designs.
The main elements of the project are the following:
- a 39,000 m³ retention tank divided in two different sectors: one for the first flush rain water and the second one acting as a retention basin. The depth of the basin reached -11m below ground level.
- a pumping station with a capacity of 18 m³/s that loads a water tower located above ground level. From the water Towers 3 pipes, with a diameter of 2000mm, discharge the water at 1,2 km from the sea shore.
- the pumping station is served with a noteworthy electric cabinet with a capacity of 4 MW (7 of the largest pumps manufactured in the world).
