In this context, the study of the physical, hydrological, and geomorphological characteristics of these units becomes essential to support efficient and sustainable management actions. Therefore, the present study aims to evaluate the morphometric indices of the Sergipe portion of the Real River Watershed through the use of geotechnologies, seeking to interpret its hydrological behavior and susceptibility to flooding and erosive processes. The indices related to basin geometry, such as form factor (0.13), compactness coefficient (2.63), circularity index (0.14), and elongation ratio (0.40), indicate an elongated shape that favors the distribution of runoff over time. This behavior is reinforced by the high concentration time (78.8 h), characterizing a slow hydrological response. On the other hand, the relief parameters reveal conditions favorable to soil erosion processes. The high altimetric amplitude (604.39 m), associated with the ruggedness index (116.65) and relief ratio (4.44), indicates rugged terrain. Drainage density (1.77 km/km²) and hydrographic density (1.107 streams/km²) demonstrate a well-developed drainage network, contributing to efficient water runoff, but also to sediment transport. Additionally, the low slope of the main channel (0.00221 m/m) may favor sediment deposition along the watercourse. Therefore, the watershed presents low susceptibility to flooding; however, it exhibits favorable conditions for the occurrence of water-induced erosive processes, especially in areas with steeper slopes.

In this context, the Brazilian National Solid Waste Policy (Law No. 12,305/2010) establishes objectives, principles, instruments, and targets for the efficient management of waste, requiring companies to implement a Solid Waste Management Plan (SWMP). Thus, this study aims to analyze the solid waste management practices of an electric shower manufacturing plant located in the state of Sergipe, Brazil, in order to propose improvements to the existing system. The research was conducted through a literature review on solid waste management, complemented by technical site visits and analysis of internal technical documents. Overall, the results indicated the need to update the management plan, particularly regarding solid waste classification in accordance with NBR 10.004:2024, as well as to implement improvements in the processes of segregation, storage, treatment, and material recovery. These actions contribute to environmental preservation and promote the enhancement of the company’s environmental management practices.

The research is based on the observation that, despite being situated in an urbanized area, Prainha faces a historical neglect by public authorities in providing essential services such as water supply, sewage collection and treatment, solid waste management, and urban drainage. This situation reveals an ongoing process of deterritorialization, degradation of local ecosystems, and disruption of traditional ways of life, reflecting structural patterns of exclusion and social invisibility. The methodology adopted includes document analysis, on-site observation, and the use of geoprocessing technologies to map the environmental and socioeconomic conditions of the community. The data indicate that, despite the high sanitation coverage rates reported for Aracaju, the reality in Prainha starkly contrasts with these official figures, exposing a significant disconnect between the reported statistics and the lived experiences of traditional populations. The lack of adequate sanitation not only compromises public health but also exacerbates sociospatial inequalities and environmental conflicts, as the degradation of local water resources has intensified with the industrialization of the surrounding neighborhood, directly impacting the quality of life for Prainha's residents. The findings suggest that achieving universal access to basic sanitation, as envisioned by the National Basic Sanitation Policy (Laws Nº. 11,445/2007 and Nº. 14,026/2020), remains a distant goal for communities like Prainha, which continue to be marginalized and disproportionately exposed to socio-environmental risks. It is concluded that overcoming this scenario requires not only the expansion of physical infrastructure but also the strengthening of public policies that recognize the territorial and cultural specificities of these populations, promoting socio-environmental justice as a guiding principle for sustainable urban planning.
