In the present work, an application was developed with the help of MATLAB software to accompany the design and maintenance phases of the implementation of surface flow constructed wetland projects. This application is freely available under the name HumePUCP for download at the following link: https://bit.ly/3k2hOs7 . The thesis work proposes a first approach for an optimized design of constructed wetlands based on the existing literature. On the one hand, there are various authors who propose different design equations based on surface area. These equations have typical design constants which, due to their nature, do not provide adequate designs since the conditions under which they were formulated vary according to the various local conditions. This ultimately translates into oversizing and increases in construction and maintenance costs. To this challenge are added the various considerations that must be taken into account to design based on different water quality indicators. Faced with this complexity, the built application takes the four most used models for wetland design in the literature and allows the integration of the following pollutants (BOD5, SST, NT, NH4, PT and NO3). The application allows to study the variables involved in the typical design models for constructed wetlands in order to compare and choose an optimized design (lower surface area). A follow-up phase is included (if the user has data) with stochastic analysis tools to modify the selected parameters and optimize the design constants of a surface flow wetland. Likewise, the user can manage the collected data and evaluate statistical indicators such as variance, mean and efficiency in order to understand the behavior of the constructed wetland. Likewise, the application allows the generation of a report of the wetland design (standard format) in PDF in order to allow cooperation between users and technicians so that in the future it is easy to share the data generated and the considerations of wetlands built in the region. In the same way, the application code is provided so that the tool worked here may eventually serve as a basis for future engineering projects related to artificial wetlands. Finally, to corroborate the requirements in the field and incorporate the pertinent functionalities within the application, a 15.0 m2 surface flow artificial wetland was implemented in the Chincheros district, Urubamba province, Cusco region. The project was designed based on the removal of BOD5 and TSS. It was found that the design constants suggested by the author R. Reed regarding BOD5 removal are good approximations, obtaining a value of p = 0.329, indicating that there is not enough evidence to affirm that what the model predicts and the measurements of pollutant in the field are very different; that is, the model and the constants used are predictive. On the other hand, the model used for SST and field measurements were uneven using a constant of K20 = 1000.0 m / year in the design according to the R. Kadlec model. According to the stochastic analysis carried out with HumePUCP this should be approximately 150.0 m / year.
