Operation & Maintenace


The operation and maintenance of productive units may surge as final stage inside the executive chain of an EPCM project, or as an activity of service for installations corresponding to projects executed by third parties. Whichever the case, Eathisa does these services, both of operation as of maintenance, through its specialized personnel.

One point to highlight is the experience that Eathisa has acquired as operator of, for example, wastewater treatment plants, it has been constituted in a valuable contribution in the generation of its engineering projects, which use these experiences for giving solutions not only oh high technical efficacy but also operative.
