Implementation, Performance and Waste Management Analysis of Decentralized Wastewater Treatment Systems Using BIM Technology

Brazil has more than 23 million inhabitants in rural areas without adequate sewage collection or treatment, which corresponds to 75% of the rural population. The absence of adequate sanitary conditions can cause disease and harm the environment. Decentralized wastewater treatment systems are alternatives to ensure the health of the population and at the same time maintain the environmental integrity of these locations. However, several projects in this area do not include important data for the construction, good performance, and operation of these systems. This partially nullifies the benefits of collecting and treating effluents. Currently, the Building Information Modeling (BIM) methodology fits into this scenario as a possibility for technological innovation and progress in productivity and project presentation. However, there are two barriers to the implementation of this technology in the production of hydraulic and sanitary projects: the scarcity of studies related to the management of the design process of these systems and the lack of BIM components that represent decentralized wastewater treatment systems. This work presents the development of a technological artifact with the potential to fill these gaps: a template created in Autodesk Revit software with several components of decentralized wastewater treatment systems available for use in projects. It is not simply a catalog in which the designer can choose the equipment to be used, but components that provide productivity in the project design, learning and flexibility in the construction of the models, fitting to the market standards.
