Due to the conditions of the original dam which did not guarantee work safety, Palma Sola was completely removed to build a brand new dam which is 14 m high, with a granular filter in its base, a rockfill protection in the upstream slope and grass protection in the downstream slope. Together with the new dam, a water intake was built on the right side of the river. This vertical tower was combined with a deviation work. Both water exits are controlled by guillotine style floodgates. Conduction through the dam is created by a 2 x 2 reinforced inch diameter pipe. The emergency spillway is made up of a thin ridge wall measuring 30 m long in order to discharge a maximum avenue of 100 m3/s. The return period is calculated at 100 years. A rectangular reinforced concrete canal with vertical drops was built to reduce the water erosion speed before reaching the creek’s natural stream.
