RESUMO

The city of Recife, is located at the coast of north-eastern Brazil and has 218.7 km of area. Its population in 2000, was 1,422,905 inhabitants (IBGE, 2000), representing 17.97% of the Stateâs population and 42.61% of the metropolitan region. As well as the majority of the Brazilian cities, does not have with satisfactory sanitary sewage collection and treatment systems. In Recife, the sewage collection systems correspond to less than 30% of the city area, and are predominantly of the conventional kind. The collective sewage system is a technology suitable for the Brazilian reality, due to its low capital cost and the adaptability to the Brazilian settlement pattern. This kind of system allows a descentralised implementation, according to the availability of financial resources and makes possible to consult the public opinion in decision processes, related to the project implementation, its operation and maintenance. In Recife, beyond the conventional systems, collective sewage collect systems have been implemented since 1982, aiming to minimise the lack of basic sanitation in Recife. The aim of this work was to analyse the causes that lead for a peccary operational conditions of the collective sanitary sewage system implemented at Mangueira district in the city of Recife, in the Brazilian State of Pernambuco. The specific objectives were to study the populationâs satisfaction degree concerning the adoption of the collective sanitary sewage system, its operational data and its technical aspects. The methodology employed in this work is based on quantitative techniques, through questionnaires distributed among the local population. Social and economic dada were collected, as well as the creation of a database of the conditions of environmental sanitation, assessment of populationâs satisfaction with the sanitary system, evaluation of operational and technical aspects of the project and the comparison with the proposed system and the actual installation. The universe of this research is composed by 300 households linked with the communitarian sanitary system within the studied area. The variables and environmental guidelines served for delimiting the sectors where the questionnaires could be applied. With the obtained results, it was possible to conclude that the communitarian sanitary system at Mangueira district did not work properly. It presented many problems, such as obstructed connections, obstructed boxes, bad smelling, swage feedback, internal blockage of the hydro-sanitary facilities, obstruction of the sewage collector and inspection windows obstructed. These problems occurred particularly where connections were installed near the walker. For the suitable and properly operation of such system, it is required to adopt an action plan, i.e. to promote an educational sanitary programme and create an environment thinking among the population; to promote a marketing programme in favour of the communitarian sanitary sewage system, to enhance and speed up the maintenance procedures for the system; and to conclude the household links with the system
