In 1998 the National Health and Social Action Ministry set in motion a plan for improvements in health facilities in its area.

As a part of this plan, COINTEC was in charge of The Remodeling of the Sanitary Drain and the Treatment System of Colonia Montes de Oca, Open Door, Buenos Aires Province.

The work involved the survey of the existing facilities, basic engineering for effluents treatment in two mechanized and aerobic plants and the preparation of the bidding conditions so as to call for public bidding.

Furthermore, it dealt with the remodeling of the Medium and Low Voltage Power Supply System and the Outdoor Lighting System.

The scope of the tasks performed was similar to the ones of the Drainage System.
