The contract, which will cost 12.9 million, was delivered to the company Accyem Proyectos and should be completed in 330 days.
The Corporación Eléctrica del Ecuador (Celec EP) awarded and signed the contract to carry out the works corresponding to stage 0 to protect the catchment of the Coca Codo Sinclair hydroelectric plant. The amount of the contract is $ 12.95 million and the execution period is 330 calendar days.
The contract was signed with the company Accyem Proyectos Cía. Ltda., Which was one of the eleven applicants, between national and international, who participated in this process, complying with legal processes. The resolution was adopted by the General Management of Celec EP after accepting the recommendation made by the Technical Commission designated for the development of this contracting process.
The protection work will be located 1.2 km downstream from the catchment works of the Coca Codo Sinclair plant, according to the study by the Lombardi consultancy. These works will begin during this dry season on the Coca river, explained Celec’s general manager, Gonzalo Uquillas Vallejo.
The contract, which will be administered by qualified personnel from the Rio Coca Executive Commission, It contemplates the construction of cofferdams (temporary structure to channel the flow of water) for the management of the river of the first pile screen and of the directional breakwaters to face surface erosion. The river diversion works are intended to isolate enough space on the ground where the control works (rigid screens) will be implemented.
In a complementary way, the construction of two breakwaters to re-establish the flow of the river towards the right sector of the channel, therefore, in the event of an eventual arrival of erosion, the flow will be directed towards the control works.
In parallel, the Río Coca Commission advances with the process of removing the accumulated sediments downstream of the old San Rafael waterfall and that they were housed at the height of the discharge channel of the turbine waters of the hydroelectric plant, as well as in the contracting process for the construction of a wall and breakwaters with hexapods and rock walls to protect the discharge channel of the Coca Codo Sinclair plant. .
The regressive erosion of the Coca River and its tributaries (Quijos and Piedra Fina) has generated the destruction of a segment of the Quito-Lago Agrio highway (El Reventador), and generated the paralysis of the pumping of crude from the SOTE and OCP pipelines.
