Utilização do sistema condominial como alternativa de esgotamento: histórico, fundamentos e comparação com um sistema convencional

Abstract

In Brazil sanitation is a constitutional right and its absence or inefficiency causes a lot of damage to the environment and human health. It presents the history of sanitation services in Brazil and abroad, current data relating to sanitation in the country, the impacts of inadequate management of sewage, etc. From the latest statistical data, it concludes that the lack of sewage is a problem that still affects many Brazilians, becoming worrying when they cause harm to human health and the environment. Therefore, it mentions alternative forms of the sewage collect that have been studied over the years in order to reach that gathering places of difficult access. The study focuses on condominial system, one of these alternative forms of use starting in the '80s and has been deployed in some Brazilian cities, like Salvador and Natal as well and the Federal District. To demonstrate the advantages mentioned by some authors, the research suggests a comparison between a conventional system (separator absolute) and condominial system. Uses for this, a study area in the “Cidade Industrial de Curitiba” (CIC), located in the southwestern city of uritiba-PR. Initially brings concepts, history, design criteria, and information about the condominial system. From this, it presents initial results as the technical advantages of the system, such as the fact waive scaling extension in the condominial. With the strokes of the two collection networks and with the aid of the software 's Sancad and Maxor for sizing and budget, respectively, allows the amount to be done and the estimated cost for the implementation of each work. Finally, brings final results as a quantitative comparison between the two systems, proving the lower use of pipe in the condominial, the possibility of using network background batch without having to expropriate the area. The cost of the condominial system deployment resulted in nearly R$ 353,000 unless the deployment of the conventional system.
