OUR WORK

main projects

Over 28 years we have worked on a wide variety of projects as shown further. However we specially take pride in the fact that we have been precursors participating in works related to the Special Projects of Clean Water and Sanitation of the Valley of Mexico, an achievement that we want to highlight.

 

These projects represent the response to a demand, derived from the excessive growth of human settlements and the lack of urban planning in regards to the existing services, which exceeded the capacity to supply clean water and maintain the sewer system.

 

New developments have caused the overexploitation of underground waters beyond their natural recharge capacity and have exceeded the drainage system adding more adverse effects to existing problem of the constant ground sinking in the valley caused by the infrastructure.

 

The challenge has been to recover the hydrological balance in the Basin of the Valley of Mexico and to contribute decisively to the sustainability of the Metropolitan Area in the medium and long terms. For that purpose we are thoroughly committed and we have been honored to have worked in some of the most impressive and representative of such Special Projects.

Casa Colorada Profunda

Planning, constructing and starting-up of the pumping plant of residual and combined waters of 40 cubic meters per second. Equipped with 20 pumps of 2 meters 3 per second each operated by engines running on diesel with installed capacity of 20,000 hp, construction of 3 ports at 30 meters and interconnections between ports of 5.8 meters in diameter. It is one of the world’s largest pumping plants of its kind, built on a lacustrine area over saturated grounds, applying the newest procedures of highly specialized deep foundation.

It consists of hydraulic works, edification, urbanization and electromechanical works.
