DIAGNÓSTICO DO SISTEMA DE ABASTECIMENTO DE ÁGUA DO INSTITUTO FEDERAL GOIANO CAMPUS URUTAÍ

Abstract

This study presents a technical and operational diagnosis of the water supply system of the Instituto Federal Goiano – Campus Urutaí, supplied by the Palmital Stream and treated in a conventional Water Treatment Plant (WTP). The objective was to evaluate the physical-chemical and microbiological quality of raw, treated, and distributed water, as well as the operational efficiency of the WTP, based on Brazilian drinking water standards (GM/MS Ordinance No. 888/2021). Samples were collected during the dry and rainy seasons at the intake point, WTP outlet, reservoirs, and drinking fountains on campus. The results showed high turbidity removal efficiency (>95%) and satisfactory performance of the coagulation, flocculation, sedimentation, and filtration processes. However, non-compliance was observed regarding free residual chlorine in the distribution network, with occasional detection of coliforms at consumption points, indicating possible recontamination. The system was classified as technically functional but operating close to sanitary safety limits, requiring operational, structural, and monitoring improvements. The proposed recommendations aim to improve water quality control, reduce public health risks, and strengthen sustainable water resources management on campus.
