Comparación hidráulica y económica en sistemas de alcantarillado con tubería de PRFV y PVC mediante la herramienta de modelacion sewergems, caso de estudio barrio La Joya, parroquia Cutuglagua, cantón Mejía

Abstract

This research project focuses on comparing, both hydraulically and economically, PVC and GRP pipes in the use of sewers, due to their viability as durable and resistant options, with a useful life of approximately 50 years. Currently, the La Joya neighborhood has a combined sewer network built with PVC pipes. The sewage systems in the country do not have a preventive maintenance plan, so it is necessary to explore other types of materials that do not require continuous and expensive maintenance throughout the useful life of the project, thus avoiding affecting the residents of the country. the study area in the future. To evaluate the hydraulic performance of the system, the SewerGems modeling software was used, proposing two scenarios: one with PVC pipes and the other with GRP pipes. The same network layout was followed for both cases, adjusting the design conditions in accordance with the technical sheets provided by the local supplier, Rival. The results of the hydraulic comparison, obtained from the modeling and supported by a manual spreadsheet made in Excel, showed that the PVC pipes better satisfy the design conditions for the case study, complying with the speed ranges and filling ratio. On the other hand, GRP pipes do not meet the design conditions, since the velocities exceed the maximum limit recommended by the supplier. On the economic aspect, it was evident that PVC pipes are significantly cheaper than GRP pipes.
