The Concepción Dam near the capital Tegucigalpa was built in order to provide the capital with drinking water. It bars the course of the Rio Grande 12km from the city, creating a reservoir with a net capacity of 33 million m³.
THE PROJECT: CHALLENGES AND SOLUTIONS
From a technical point of view, the project was an avant-garde structure, being one of the first to be constructed using the RCC (Rolled and Compacted Concrete) method, which reduces costs and accelerates completion: it involves laying the concrete using ordinary earth-moving equipment , thus saving labour costs, and compacting it with vibrating rollers. With this equipment and these technologies, it was possible to exploit to the utmost both available resources and local conditions, leading to the project’s winning the prestigious Ingersoll-Rand Italia prize for 1991 (for the best work designed and constructed abroad by Italian firms), for having solved Tegucigalpa’s dramatic water supply emergency in record time. Indeed, owing to this emergency, the detailed design was largely developed during the works. The Concepción Dam however is distinguished not only for technical reasons. In actual fact Tegucigalpa was, and still is in part, one of the thirstiest cities in the world, because its water supply does not manage to keep up with its population growth. Today, the city numbers one million inhabitants (which will double in 23 years) and only 550,000 have enough water, even in summer. The project also included the road connection between the dam, the water treatment plant and the city. The road crosses a hilly area with difficult morphological and geological conditions (slopes subject to landslides), which necessitated their stabilisation.
