Abstract

This technical project consists of improving the sanitation and wastewater treatment system in the community of El Santuario, Quero canton, Tungurahua province, deteriorated by population growth and lack of maintenance over the years, which has altered the quality of life of its inhabitants and the incorrect use of the resource for agricultural irrigation. To this end, the basic information for the project was collected, consisting of a topographic survey of the pipe networks and sewerage wells, a population census, inspection of the physical sanitary infrastructure, flow measurement campaigns, and wastewater characterization. The purpose was to verify the hydraulic capacity of the collection network and the efficiency of the current processes and unit operations for wastewater treatment, which are: septic tank, FAFA and sludge drying bed. The results showed that four pipe network sections do not conform to the design parameters (slope and velocity limits); in addition, the current treatment train does not generate an effluent of the required quality for treated water intended for agricultural reuse specified in the TULSMA 2015 standard and the FAO guide, so the redesign of the collection networks that present drawbacks was carried out, and the incorporation of new treatment processes such as: screening, desander, grease trap, trickling filter, secondary sedimenter and artificial wetland, in addition to the improvement of existing units.
