641. Detailed Technical Drawing of Septic Tank and Anaerobic Filter System

This technical drawing provides detailed information on a domestic wastewater treatment system, comprising two main components: the Septic Tank (Tanque Séptico) and the Anaerobic Filter (Filtro Anaeróbio). This is a sanitation engineering design document, presented in Portuguese/Spanish, providing all necessary parameters for construction.

Technical Drawing Description
System Structure:

• Septic Tank (Tanque Séptico): Details the plan view (Planta) and cross-section (CORTE A). The drawing specifies the tank’s capacity (approximately 4,712 liters) along with its internal structure, such as baffles, inlets/outlets, and the sludge settling area.
• Anaerobic Filter (Filtro Anaeróbio): Details the plan view (Planta) and cross-section (CORTE B). This tank has a capacity of approximately 3,770 liters, containing filter media (like gravel/stones) and a water distribution pipe system for treating wastewater after it leaves the septic tank.

Technical Details:

• The drawing includes several enlarged details (DETALHE A, B, C, F) illustrating the installation of water distribution pipes, the structure of manholes (Tampa Cega), and concrete edge details (Acabamento do Canto) at the tank bottom.
• A table for tabulation and calculation (DIMENSIONAMENTO and CAPACIDADE) provides essential design parameters, ensuring the tank has sufficient capacity to treat the wastewater according to standards.
• Other details include how to perforate the PVC pipes for uniform water distribution within the filter media and the composition of the base finishing layers.

This drawing is an indispensable document for building an effective and sustainable on-site wastewater treatment system.
