Cenários para universalização do sistema de esgotamento sani-tário de João Pessoa

Abstract

It is well known that a shortage of sanitation has serious consequences for public health, as well as being an obstacle to the socio-economic development of a region. Consider-ing this, proper collection, treatment and disposal of sewage are important for improving the living conditions and well-being of the population. Thus, the present study approaches the elaboration of scenarios as object of strategic planning to reach a Universalization of the Sys-tem of Sanitary Sewage in the city of João Pessoa. The study consists, initially, in the analysis of the Current Scenario, based on historical series and system diagnosis. Then, it proposes four scenarios for universalization, analyzing for each horizon the growth rates, the service deficit, the number of connections and the extension of the sewage collection network neces-sary to reach the objective, in addition, it was calculated the costs for the implantation of the Sanitary System. It was concluded that it would require investments in the range of R$ 44 million per year to guarantee 100% service to the sewage network in a more optimistic sce-nario, 2030, and R$ 28 million per year to a further horizon. Based on data from the SNIS, it is known that using the average of the investments made between 2010 and 2015, it is not possible to reach the goal of universalization nor in the most pessimistic scenario. By antici-pating future behavior, the scenarios allow actions to be organized and involved in the per-spective of optimizing the results, in addition to favoring the implementation of the desired future.
