2D plans and cross-sections for three wastewater pretreatment structures: a gray water trap (trampa de aguas grises), a desander or grit trap (desarenador), and an oily water skimmer (trampa de aguas aceitosas). Each design includes detailed dimensions and structural reinforcement specifications for 3000 PSI concrete with Q4 welded mesh.
The drawing provides material quantity tables (cuadro de cantidades) covering excavation, concrete volumes, and formwork for each tank. These details are used for industrial site drainage, parking lot runoff management, and facility wastewater systems. All measurements are in meters. Trampa de aguas aceitosas.
