Previous issue date: 2011-11-04 / The growing accumulation of people in urban centers caused chronic problems of the
cities to begin to take an increasingly unsustainable. 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
