A new work of the megaproject of Environmental Improvement of the Metropolitan Area of San José of the Costa Rican Institute of Aqueducts and Sewers (AyA) was awarded firm this Tuesday, September 8, when the appeal period expired.
It is about the International tender for the “Construction and improvement of collectors and sub-collectors”, composed of two contracts, which will allow the installation or rehabilitation of a total of 31 kilometers of sanitary pipes in sectors of San José, Goicoechea, Montes de Oca, Vázquez de Coronado, Moravia, Desamparados, Alajuelita and Tibás.
With a total investment of about ₡ 27 billion ($ 45 million), the execution period for both projects is 30 and 32 months respectively, under the responsibility of the French company SADE CGTH.
The firm award was scheduled for 2021, but thanks to the fact that no appeals were received, the schedule was advanced several months, so it is estimated that the order to start the works will be given in November.
“We continue a strong investment in the Sanitation Route, which will translate into better quality of the environment, public health and better conditions for the development of cities,” said AyA’s executive president, Yamileth Astorga.
In this way, the flow of the Los Tajos wastewater treatment plant, located in La Uruca, will be increased from 430 thousand liters per second today to 533 thousand liters per second by 2025 (an increase of 23%), after connection of users to the sanitary sewer network.
The hierarch stressed that in addition to building new collectors, identified collapses in the current pipes will also be repaired. To do this, technology will be used for the first time in Costa Rica to repair existing pipes without extracting them.
