Comprehensive site plan for a sewage treatment plant (ETE) featuring integrated stormwater drainage and landscaping elements. The drawing details surface grading, pavement specifications, and runoff management systems, including concrete drainage channels, gabion stone erosion protection, and perimeter fencing. Key infrastructure components include access roads with polyhedric pavement (538 m²), concrete walkways (345 m²), planted grass areas (530 m²), and technical elements like gutter details and drainage grates. The plan incorporates environmental features including specified native tree species (Jequitibá Rosa, Sapucaia, Braúna, and Jacarandá Caviuna) and Sansão do Campo perimeter plantings. Elevation points throughout the site range from approximately 580m to 596m, with carefully designed slope gradients (2-5%) to direct surface water toward collection points and receiving water bodies (Ribeirão Douradinho and Córrego Barrinha).
