The Instituto Costarricense de Electricidad said that it will be beginning to fill the water supply for the Proyecto Hidroeléctrico Pirrís Tuesday.
The dam that has been constructed will hold 30 million cubic meters of water or about 39,238,519 cubic yards. The project includes a tunnel that takes water from the Río Pirrís. The company estimated that it will take weeks for the water behind the dam to reach its expected depth of 110 meters, more than 300 feet.
The project is in León Cortés. It is expected to provide power for 160,000 homes.
