Río Hondo feeds on the Colorado River’s hydroelectric potential from elevation range between 1,297 masl and 257 masl. It is located in the southeastern region of Guatemala . A 31 m high concrete gravity dam will be constructed, creating a reservoir with a useful volume of 1.215 million m3 and a maximum oscillation of 13 m. A 943 m low pressure tunnel starts at the dam site ( Tunnel 1) followed by a 3,295 m penstock conducing to the powerhouse . Maximum gross head of the project is 1063.97 m, and the corresponding design flow 3.89 m3 / s ,
Maximum gross head 1063.97 m
CARBON Engineering was hired by Ghella Spa to perform the basic design study for the development of technical information of the civil works for bidding documents . This study includes topographic, geological and geotechnical studies, hydrological studies , hydraulic design of the works and basic structural design, along with hydrolectric generation studies , budget and economic analysis.
