Located in the province of Viterbo, just 45KM from Rome, Nepi stands on a tufaceous promontory between two streams (the Puzzolo and the Falisco) which converge there after having formed perennial waterfalls. The Acqua di Nepi spring is located in an isolated green valley with a protection area of ​​approximately 240 hectares. The hydrogeological basin is located on volcanic soils that give the water its digestive properties and its subtle effervescence.
