📋 Tender Overview
Hydraulic infrastructure will improve and expand cultivable areas to more than 3900 meters of altitude.The regional governor of Tacna, Luis Torres Robledo, inspected on Wednesday the construction of the Calacala dam, located on the 3,900 m.s.n.m. in the district of Cairarani, province of Candarave. During his visit, he stressed that this infrastructure will be key to face droughts in high Andean areas and guarantee sustainable agricultural development.
The Calacala dam, promoted by the Regional Government of Tacna through the Special Tacna Project (PET), will be fed by the Tomacucho River, which supplies the future reservoir with an estimated flow of 200 liters per second. This important hydraulic work will have a height of 35 meters, a length of 185 meters and will store 1.4 million cubic meters of water. It will have a total investment that exceeds 32 million soles and an execution period of 14 months, under the responsibility of the Altiplano consortium.
Thanks to this dam, irrigation will arrive through a 4.6 -kilometer conduction channel, composed of profile pipe, towards the towns of Cala Cala, Yarabamba and Cairarani, ensuring the supply of more than 140 liters per second of fresh water for agricultural use.
Initially, the project contemplated benefiting 380 families. However, after the optimization of the design, more than 500 farmers will benefit and will allow the irrigation of 150 agricultural hectares, mainly dedicated to the cultivation of oregano, potatoes, corn and other products in the area.
During the inspection, the progress of the preliminary works and the operation that has begun with the excavation was verified.
The work will feature geocomposite coating, guaranteeing its durability and leak control. In addition, the executing company has already registered its first valuation for S/ 100 thousand, working without financial advance and under strict technical supervision of the PET.
As scheduled, the dam will begin to store water no later than in October 2025, and will begin to supply the peoples since September 2026, in a context where droughts are increasingly frequent in high Andean areas.
With these actions, the Regional Government of Tacna reaffirms its commitment to the agriculture and development of the province of Candarave, betting on sustainable solutions that guarantee water for today and for the future.
