Reutilización de aguas residuales provenientes de comunidades rurales en actividades agrícolas

Wastewater is considered as a reusable resource in the agricultural irrigation of rural communities, because water is a scarce resource today, so that crops are vulnerable to droughts, arising the need to seek new sources of supply. The physical, chemical and microbiological characteristics of the residual water from San Gerardo parish in Ecuador were analyzed in order to determine the viability of the wastewater reuse and also the percentage of water resources savings that this would represent. The lab results showed that is impossible to reuse wastewater without a treatment, according to the environmental norms. The most critical parameter was fecal coliforms where high concentrations (120000 NPM / 100 ml) were obtained, and the wetland plus disinfection was selected as the most appropriate technology for the removal of this parameter and taking into account the cost. The quality of treated effluent would present better water quality characteristics than those currently received from the Chambo - Guano Irrigation System. With the reusable flow of 11 lt / s generated by the 264 inhabitants connected to the sewerage network, 8 hectares of land would be irrigated, and the approximate investment cost is US $ 6864 and the cost per year of operation and maintenance through the wetland plus Disinfection is US $ 396, excluding the distribution of treated wastewater. The reuse of wastewater in agricultural activities is a viable option through low-cost treatment technologies that ensure the quality of water established by environmental legislation, generating a new alternative of supply that rural communities could consider and apply.
