After many months of relentless work, we have reached another milestone of the Seawater Protection Plan, the major water work that will eliminate drains discharging into the sea. Below the new waterfront terrace, two tanks the size of 20 Olympic-size pools are in place to keep watch over the sewage system
On 6 June 2011, a violent storm on Rimini severely damaged the city's sewage system. For a community that has been focused on summer tourism for decades, solving this problem and avoiding environmental impacts such as water pollution was an absolute priority. The sea, in fact, is not only a precious tool that drives the city's economy, but also and above all part of Romagna's identity. Now, residents and tourists no longer have to fear sudden downpours, because right in the centre of town, under a terrace overlooking the sea, there is a remarkable work of engineering that watches over Rimini's sewage system. It is part of the Seawater Protection Plan (PSBO – Piano di Salvaguardia della Balneazione), a kind of "gentle giant" that is the largest water reclamation project underway in Italy and one of the most important in Europe, also recognized by the UN for its role in protecting the marine environment.
The most important phase of the entire project began in 2016 in Piazzale Kennedy, the heart not only of coastal social life but also of the entire PSBO, with the construction of two tanks the size of 20 Olympic-size pools, located up to 40 meters below ground level, which involved excavating 70 thousand m3 of soil. One tank, with a capacity of 14 thousand m3, collects the water from the first flush of rain while the other, with a capacity of 25 thousand m3, temporarily holds and "stores" the rainwater, which can be sent to the purification plant or into the sea in the event of heavy rainfall. When average rainfall occurs, the tanks fill in 70 minutes, or 30 for particularly heavy downpours. A forced ventilation mechanism (with abatement using activated carbon filters) has solved the problem of bad odours. Lastly, to protect our beaches, over 21 thousand m3 of top-quality sand have been collected. With a view to a circular economy, they have already been used to replenish Rimini's coastline.
The Piazzale Kennedy project is the fruit of great workdone not only jointly with the Municipality, Romagna Acque and Amir, but also with all the tour operators in the area and the residents, who have endured months of hardship in such a central area of the city that, for over 60 years, has been the holiday postcard of millions of tourists, both Italian and foreign. To date, more than 5 thousand m2of coastline have been "freed" from swimming bans, and the construction work is now 90% complete. By 2024, all 11 drains discharging into the sea will have been eliminated.
The most important phases of Rimini's Seawater Protection Plan
