The submarine outfalls are the preferred solution for discharging treated domestic wastewaters due to the ocean’s assimilative capacity, as a cheaper option. If the exit systems to the sea are chosen, location is key to avoid the return of the wastewaters to the coastal area and for the marine ecosystem restoration. According to the effluent discharge control regulations dictated by the National Water Authority (Autoridad Nacional del Agua, ANA) of the Republic of Peru, the bacteria concentration level must be under a certain level in the protected area. This thesis is based on the applied research methodology, since there is not much scientific information available regarding submarine outfalls in Peru. For this reason, this research seeks to increase the scientific information so that the next projects involving submarine outfalls are more efficient in hydraulically. In the other hand, the main effects impacting dilution are coastal currents generated by the wind and the wastewaters flow into open coastal regions, as found in La Chira. The dispersion model predictions are accurate if they have the physical characteristics of the submarine outfall, the effluent and the ocean, since they provide a clear perspective for the submarine outfall planning. In this study, we compared the design flow rate with the geometric increase method recommended by the World Health Organization (WHO) with the real flow rate of the project, and it was verified that both flow rates are similar. Also, the submarine outfall hydraulic capacity was verified to identify the losses of total loads produced throughout the outfall. Furthermore, the Visual Plumes, a software that generates dispersion models of effluents in body of water, was used for the near-field and far-field dilutions of the contaminant. The results of near-field and far-field dilutions model show that the submarine outfall of La Chira meets the legal environmental regulations.
