Propuesta de mejoras a los sistemas de agua potable y saneamiento del cantón Cayambe : rehabilitación del tanque imhoff en barrio Víctor Cartagena.

Abstract

The current titling project evaluates the rehabilitation of the wastewater treatment system that corresponds to an Imhoff Tank in the Víctor Cartagena neighborhood in the city of Cayambe, the same one that was implemented years later, but is currently disabled. Wastewater is transported by the combined sewage system and is discharged directly into the Granobles River, generating negative consequences for the environment and the population. For the execution of the project, the information presented and used in the different flow and sizing calculations was obtained from technical visits and managed by the Cayambe Municipal Public Drinking Water, Sewerage and Cleaning Company (EMAAPAC). For the evaluation of the operational characteristics of the treatment system, the calculation and updating of the theoretical, measured, and future flows was determined. It was determined that the measured flows in the wastewater discharge area exceeded the calculated theoretical flows in magnitude. On the other hand, the analysis and characterization of the residual water was carried out with the results obtained in the sampling on the site and in the laboratory of the physical, chemical and microbiological parameters. The results of the characterization carried out to a large extent do not correspond to the typical concentrations of domestic waste, probably they exceed the established ranges since industries discharge their discharges without giving them prior treatment. The treatment efficiency of the Imhoff tank is not ideal for the wastewater from the Víctor Cartagena neighborhood, due to the low percentages of pollutant removal efficiency and a flow that enters the system much higher than the flow for which it was designed; for which it is essential to add an additional treatment operation such as the infiltration ditch.
