Artificial wetland proposal as a sustainable alternative for the care of the environment

Abstract

This research analyzes the technical-financial viability for the establishment of an artificial wetland in the community of Morelos in the municipality of Zaragoza, Puebla, under an environmental science approach. A substantive problem of these times is the progressive environmental deterioration caused by human activity. In the community of Morelos, the daily wastewater inflow is 149,472 liters. With the wetland proposal, treated water with 70% purification can be obtained, which can be used for garden irrigation or other activities that do not involve direct consumption. Other products that can be obtained from the wetland are ornamental plants and flowers such as the alcatraz flower, and reed, as well as humus. Financial indicators are positive. The Internal Rate of Return (IRR) is 337% of profitability, the Net Present Value (NPV) is equal to $24,669,186.70 pesos and the Cost Benefit Ratio (RBC) is 7.90. These indicate that from a financial point of view installing a wetland in the community of Morelos is viable. According to the sustainability approach, from the social point of view it is viable because it generates jobs for the people of the population; economically, it generates income and a better quality of life for the sale of treated water, plants, flowers, and humus; with a good environmental impact because it helps to reduce the contamination of the ecosystems of the area but mainly to avoid filtration into the aquifers.
