Hatillo Hydroelectric Central Expansion
This project includes construction of the second hydroelectric central using the existing hydraulic circuit where the 9.86 MW Kaplan turbine was installed. To improve operation of both turbines, the reservoir’s NAMO was increased to 1.85 m (88.35 msnm high), thus creating a flow regularization volume for generation purposes.
At the height of 86.50 msnm, the landfill has a free discharge flat peak measuring 12 m wide x 60 m de long. Downstream of the dumpsite, a structure with rectangular orifices was installed measuring 8 x 4 m, its sills located at soleras 84.00 msnm high. These orifices control the discharge when the reservoir reaches a height of 90 msnm.

Maguana River Dam
The typology chosen for this dam, located over the Maguana River (a tributary of the San Juan River), has been roller-compacted concrete (RCC). This is capable of storing a volume over 5 hm³ with a basing of 1.250.000 m². With a fixed lip slipway and a 20 m length, it is incorporated to the reservoir, with a smooth surface design that pours the water over a stilling pool wide x 20 m long. The deviation of the Maguana River was conceived in two phases. In the first phase, rock septa were installed at the deviation’s entry and exit points, specifically at elevations 614.00 msnm and 608.00 msnm. Once the canal was completed, the septa were removed to build the cofferdam downriver at an elevation of 610.00 msnm. After closing the river course, the second phase works will allow for the construction of the dam and spillway, as well as the water outlet structures for the hydroelectric central and the draining system.
The water outlets for the hydroelectric central are located at 621.00 msnm high and the forced conduit follows some 2.5 km parallel to the access up until the hydroelectric central. The drain outlet at the base is located at an elevation of 505.00 msnm, with a fixed grille and stoplog flood gates. Down river, at the control building, two flat flood gates, 2 x 2 m, will be built in a bureau style.

Palma Sola Dam
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.
Servicios provided by the firm:
• Design of the dam
• Design of the intake and unloader.
• Design of the landfill with a 100 m3/s flow
