Nicaraguan Team

Sergio Romero demonstrating the use of the chlorine test kit that is standard for all chlorinator installations. This simple and rapid test ensures that the dose of chlorine is sufficient to remove disease causing bacteria yet the chlorine is not detectable in the taste of the water. Matagalpa, 2021.

Including the current project and all previous chlorinator installations under the direction of project Director Sergio Romero, TASCA will have installed a total of almost 400 chlorinators. These chlorinators supply a population of 450,000 people in the rural Nicaraguan Departments of Jinotega and Matagalpa with uncontaminated drinking water.
What the three person team has is accomplished is admirable considering that Sergio and Marlon had to reintroduce the project to the rural communities. First they had to notify the communities that we were once again back in business, then visit communities explaining how the project worked, additionally train the community water committees in the construction, installation and maintenance of a chlorinator, and finally be available for follow up.
