Estudo comparativo dos aspectos sociais e econômicos entre os modelos de esgotamento sanitário convencional e condominial

Abstract

The set of measures and actions aimed at ensuring adequate health and quality of life for the population is known as Basic Sanitation. In a broader sense, addressing issues such as the proper disposal of solid waste, the supply of potable water, wastewater treatment, and the control of disease vector populations makes caring for basic sanitation one of the most essential duties of the State. However, in recent years, the State has neglected one of the most crucial pillars: the treatment of effluents to prevent environmental contamination and protect public health. In the conventional sanitation system, the responsibility for the collection, treatment, and disposal of sewage falls to the public sanitation service or specialized companies contracted by municipalities, while in a condominium model, the management of effluents is the responsibility of the condominium administrators. This scientific work aims to highlight these differences through a comparative analysis of autonomy, efficiency in collection, treatment, and maintenance, particularly determining the economic and structural viability for implementing the best model for new developments. Utilizing a model subdivision in the urban area of the state of Piauí, two different layouts were designed following technical parameters for pipe placement on public roads and sidewalks. This design was based on calculation parameters established by NBR 9649/1986 and employed the software CEsg ® - Automatic Calculation System for Sanitary Sewage Networks. The budget spreadsheets were developed with the aid of Microsoft Excel ®, 2016 version, using price bases SICRO, SINAPI, and ORSE for construction in Brazil
