The Detailed Design, Bill of Quantities, and Budget were prepared, and the Specific Technical Specifications were prepared for the construction of a sewer system and a wastewater treatment plant in Fray Mamerto Esquiú and Valle Viejo, designed to serve a future population of 70,000 residents, with 12,000 new service connections.

The project consists primarily of gravity pipelines, totaling approximately 240 km of network and 5 pumping stations. PVC and FRP pipes with diameters ranging from 160 mm to 800 mm will be used. The treatment plant consists of 4 sets of stabilization ponds, involving the movement of approximately 850,000 m³ of soil.

In addition, an Environmental Impact Study was conducted, including an Environmental Management Plan and Mitigation Measures, as well as an Economic Evaluation of the project that included an analysis of technical alternatives and calculations of economic and financial profitability.
