The project proposes improvements to the wastewater collection and treatment, and the construction of a new wastewater treatment plant, for which failing collection lines will be replaced and new lines will be installed to provide coverage and connect 100% of the existing population. In addition, a new wastewater treatment plant of 140 lps capacity, comprised of facultative lagoons will be built to prevent contamination of the Rio Grande’s main course, the ground and local water tables.
