In this context, this study aimed to develop a conceptual design for the sanitary sewage system of the Cajuanguawa community, located in the Assurini do Trocará Indigenous Territory, Pará State, Brazil, proposing a technical solution compatible with local conditions. This applied research adopted a qualitative and quantitative approach through a case study. Initially, the existing sanitation system was assessed based on technical documents, field inspections, and information obtained from a sanitary and environmental technical assessment. Subsequently, the design population and domestic wastewater contributions were estimated to support the development of two conceptual alternatives based on decentralized wastewater treatment systems. The alternatives were evaluated using technical, operational, economic, environmental, and sociocultural criteria, considering the specific characteristics of the Indigenous community. The assessment revealed structural and operational deficiencies in the existing system, including flooding, maintenance difficulties, low acceptance of dry toilets, and reduced sanitary performance. Among the evaluated alternatives, the system consisting of a household sanitary module, septic tank, anaerobic filter, and soakaway pit showed the best overall performance, mainly due to its construction simplicity, ease of operation, lower implementation cost, and greater compatibility with local conditions. The findings demonstrate that the proposed methodology provides a technically feasible and context-appropriate solution, supporting future design and implementation stages of wastewater systems in Indigenous communities and other isolated rural areas. Furthermore, the study highlights that conceptual design based on technical, operational, and sociocultural criteria is an effective approach for selecting appropriate wastewater treatment technologies in Indigenous territories.Acesso AbertoSaneamento indígenaSistema individual de esgotamento sanitárioEstudo de concepçãoTanque sépticoComunidades ruraisIndigenous sanitationDecentralized wastewater treatmentConceptual designSeptic tankRural communitiesCNPQ::ENGENHARIAS::ENGENHARIA SANITARIA::SANEAMENTO BASICO::INSTALACOES HIDRAULICO-SANITARIASTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
