Análise orçamentária do sistema Tewetland como solução coletiva dentro do saneamento ambiental

Abstract

With the alarming lack of national coverage of sanitation services and the advancement of studies and technologies in tune with the environment, new sewage alternatives inspired by nature itself emerge as a possible solution to improve this situation. In this context, this work aims to carry out a budget analysis of the TEWetland system, a technology developed by the Aquatic Ecology Laboratory/UFPB, as a collective solution within environmental sanitation. The analysis was carried out based on a case study for six hypothetical scenarios, with variation in the number of residences, starting from the creation of sizing and budget spreadsheets for systems whose objective is to serve a pre-defined number of residences and inhabitants, generating a certain amount of effluent. The results indicate that, despite being innovative and with a lot of space to explore new possibilities of materials and designs, the technology proved to have a high cost for its application, above R$ 1,000.00/habitant, according to some considerations. The study concludes that the area of environmental sanitation is still in its embryonic stage and needs more attention and investment from public authorities, to accelerate its growth and be able to reap rewards in the future, with the technology used in the work being an example.
