Primarily related to lack of infrastructure coupled with sanitation and lack of investment in critical sectors such as health, education, housing and transportation, these problems start to deteriorate markedly the quality of life of city dwellers and put into test management policies of the spaces urbanized. To reverse this situation, shows is essential to the use of tools (highlighting this harvest rates and environmental indicators) that help in assessing the current conditions and may assist in predicting future scenarios. From the information listed above, now put the research seeks to present an index called ISBA Environmental (Sanitation Index) which looks at the four urban systems (water, sewer, solid waste and urban drainage) from the viewpoint of application in a geographical cutout specific - in this case the Drainage Basin XII, defined by the Plan of Urban Drainage Stormwater in the city of Natal, capital of Rio Grande do Norte. This index, together with analysis of other factors sought to trace the current conditions of the basin and thus, assist in proposing the best solutions. For the preparation of the index was applied a questionnaire with a sample of 384 (three hundred eighty-four) households that aimed to study two variables: access to services and satisfaction of the population in relation to these. The ISBA has shown that the system is the most deficient collection and disposal of effluents (ICE = 47.66%), followed by the drainage of rainwater (IDAP = 54.17%), water supply (AAI = 61, 36) and solid waste collection (IRS = 78.28). With the ISBA was possible to verify that the qualitative data shows whose subjectivity is evident (as is the case of user satisfaction) can be of great importance when an assessment, since we obtained the correlation coefficient between the variables "Access" and " Satisfaction "equal to 0.8234, showing a strong correlation between the existence / quality of service offered and the impressions of the population that receives them / O crescente ac?mulo de pessoas nos centros urbanos fez com que problemas cr?nicos das cidades passassem a tomar propor??es cada vez mais insustent?veis. Relacionados principalmente a falta de infra-estrutura de saneamento e somadas a falta de investimentos em setores cr?ticos como sa?de, educa??o, habita??o e transporte, estes problemas passam a degradar acentuadamente a qualidade de vida dos citadinos e colocam em teste as pol?ticas de gest?o dos espa?os urbanizados. Para reverter tal quadro, mostra-se imprescind?vel o uso de ferramentas que auxiliem na avalia??o das atuais condi??es e possam auxiliar na predi??o de cen?rios futuros. A partir das informa??es elencadas supra, a presente pesquisa busca apresentar um instrumento ambiental denominado ?ndice de Saneamento B?sico (ISBA) que visa a analise dos quatro sistemas urbanos (?gua, esgoto, res?duos s?lidos e drenagem urbana) sob a ?tica de aplica??o em um recorte geogr?fico especifico no caso a Bacia de Drenagem XII, definida pelo Plano de Drenagem Urbana de ?guas Pluviais da cidade do Natal, capital do Rio Grande do Norte. Este ?ndice, juntamente com an?lises de outros fatores ajuda a tra?ar as atuais condi??es da bacia e com isso, auxiliar na proposi??o das melhores solu??es. Para a aplica??o do ?ndice foram utilizados obtidos atrav?s de um question?rio com uma amostra de 384 (trezentos e oitenta e quatro) resid?ncias que objetivava estudar duas vari?veis: acesso e a satisfa??o da popula??o aos servi?os de saneamento. O ISBA mostrou que o sistema mais deficit?rio ? o de coleta e destina??o final de efluentes (ICE=47,66%), seguido pela drenagem de ?guas pluviais (IDAP=54,17%), o abastecimento de ?gua (IAA=61,36) e a coleta de res?duos s?lidos (IRS=78,28). Com o ISBA foi poss?vel verificar que dados qualitativos cuja subjetividade mostra-se evidente (como ? o caso da satisfa??o dos usu?rios) podem ser de grande import?ncia quando de uma avalia??o, visto que se obteve coeficiente de correla??o entre as vari?veis Acesso e Satisfa??o igual a 0,8234, mostrando grande correla??o entre a exist?ncia/qualidade de servi?o oferecido e as impress?es da popula??o que os recebe
