Hydraulic Modeling of a Sanitary Sewer Network. Case Study in Mexicali, Baja California, Mexico

Abstract

Worldwide, access to adequate sewer systems represents a challenge, especially in cities in developing and underdeveloped countries. In this context, hydraulic modeling of sewer networks is considered a key tool to ensure the efficiency, safety, and sustainability of hydraulic systems. This research aimed to diagnose and propose improvements to the sewer infrastructure in a representative polygon of the city of Mexicali, Baja California, Mexico, through hydraulic simulation. As a methodology, technical information was collected on materials, pipe diameters, number and location of manholes, network age, and estimated service life. The data was subsequently processed, and specialized software was used to simulate system behavior. The results made it possible to identify operational deficiencies, areas at risk of hydraulic overload, and to estimate system capacity for future demands. Furthermore, it is evident that hydraulic modeling contributes to optimizing resources, reducing costs, and improving decision-making. In conclusion, hydraulic simulation is not only useful in network design but also acts as a strategic tool for public management, sanitation strengthening, and sustainable urban development.
