Rimini has a long history of tourism development (the first bathing establishment opened in 1843), being one of the first mass-tourist destinations at the beginning of the 20th century and reaching a mature stage already in the 1960s. The massive tourist development resulted in indiscriminate exploitation of natural resources, including water. Recently, the city of Rimini has played a pro-active role in analyzing and proposing sustainable forms of coastal tourism. RomagnaAcque – Società delle Fonti is the regional water supplier and it provides wholesale water to HERA SpA, the main retail water company in the provinces of Ravenna, Forlí-Cesena and Rimini (more than one million permanent residents and millions of tourists). The most important water source is the artificial reservoir of the Ridracoli Dam, which meets about 50% (around 60,000 m3/year) of the region total water requirement. The water for the city of Rimini is supplied partially from the Ridracoli reservoir and partially from local groundwater well fields.
