This program can be used as a complementary tool for university education or for updating of knowledge of pavement designers. Those individuals programs make up the computational package called UTPLPave, which is a free online version and it was developed using JavaScript libraries in HTML5 and BootStrap. In this context, this study aims to develop software for designing flexible pavements, rigid pavements and overlayer on the flexible pavement, which allows users to observe the procedure carried out by the program. Therefore, several computer programs have been developed using this methodology, however, they only show the results and not the process to get to these ones. Figures, tables, and equations are used in this methodology, which could confuse an inexperienced designer. For the design of pavements, one of the most used methodologies in Latin America is the proposal for AASHTO in 1993. The pavement structural design of one road is one of the variables that can most influence the cost of construction and maintenance of the pavement. The ranking result indicated that stabilization pond, constructed wetland, soil filter, use of aquatic plants, and reuse of wastewater for irrigation ranked from best to worst respectively. For the evaluation, different criteria were used such as land requirement, pollutant removal capacity, health risk, capital cost, hydrogeological risk, maintenance cost, subject to seasonal variability, and ecological benefits. In this study, the efficiency of five several natural wastewater treatment approaches namely waste stabilization pond, soil filter, constructed wetland, use of aquatic plants, and reusing of wastewater for irrigation were compared using VIKOR. Recently, the world is demanding the wastewater treatment systems which is affordable economically and technically, carbon-free and ecological friend. Wastewater treatment is the method for the elimination of pollutants from effluent to release the effluent to the environment that has a pollutant concentration at an acceptable limit or to directly reuse the water.
