Establish a methodology that can serve as guidelines for future projects controlled reuse of water like this was the objective of this research. Been proposed, implemented and evaluated three instruments of sanitary and environmental control: 1) adaptation of sewage treatment plant and quality control of the treated effluent 2) analysis of soil-nutrient interaction in the irrigated area, 3) knowledge of the local hydrogeology, especially with regard to the direction of flow of the aquifer and location of collection wells of Companhia de ?guas e Esgotos do Rio Grande do Norte (CAERN) situated in the surroundings. These instruments have proven sufficient and appropriate to ensure the levels of sanitary and environmental control proposed and studied, which were: a) control of water quality off the STP and the output of the irrigation reservoir, b) control of water quality sub surface soil and assessment of progress on soil composition, c) assessment of water quality in the aquifer. For this, we must: 1) establishing the monitoring plan of the STP and its effluent quality sampling points and defining the parameters of analysis, improve the functioning of that identifying the adequacy of flow and screening as the main factors of operational control, and increase the efficiency of the station to a relatively low cost, using additional filters, 2) propose, implement and adapt simple collectors to assess the quality of water percolating into the soil of the irrigated area, 3) determine the direction of groundwater flow in the area study and select the wells for monitoring of the aquifer. / A pesquisa da qual resultou esta disserta??o desenvolveu-se na UO RNCE da PETROBRAS, em Natal, que implantou um projeto de uso racional e re?so de ?guas, com aproveitamento do efluente de uma Esta??o de Tratamento de Esgotos (ETE) j? existente no local, dilu?do com ?gua de po?os, para irriga??o da ?rea verde do complexo de pr?dios corporativo da empresa. Estabelecer uma metodologia que possa servir de orienta??o para futuros projetos de re?so controlado de ?guas semelhantes a esse foi o objetivo desta pesquisa. Foram propostos, implementados e avaliados tr?s instrumentos de controle sanit?rio e ambiental: 1) adequa??o da esta??o de tratamento de esgotos e controle da qualidade do efluente tratado; 2) an?lise da intera??o nutrientes-solo na ?rea irrigada; 3) conhecimento da hidrogeologia local, principalmente no que diz respeito ? dire??o do fluxo do aqu?fero, e localiza??o dos po?os de capta??o da Companhia de ?guas e Esgotos do Rio Grande do Norte (CAERN) situados no entorno. Estes instrumentos mostraram-se suficientes e adequados para assegurar os n?veis de controle sanit?rio e ambiental propostos e estudados, que foram: a) controle da qualidade da ?gua na sa?da da ETE e na sa?da do reservat?rio de irriga??o; b) controle da qualidade da ?gua no solo sub superficialmente e avalia??o da evolu??o da composi??o do solo; c) avalia??o da qualidade da ?gua no aq??fero. Para isso, foi necess?rio: 1) estabelecer o plano de monitoramento da ETE e da qualidade do seu efluente definindo pontos de amostragem e par?metros de analise, melhorar o funcionamento da mesma identificando a adequa??o da vaz?o e do peneiramento como principais fatores do controle operacional, e aumentar a efici?ncia da esta??o a um custo relativamente baixo, com uso de filtros adicionais; 2) propor, implantar e adequar coletores simples para avaliar a qualidade da ?gua percolada no solo da ?rea irrigada; 3) determinar a dire??o do fluxo subterr?neo na ?rea de estudo e selecionar os po?os para monitoramento da ?gua do aq??fero.
