If we talk about serious drainage, then these are quite complex systems of pipe branches underground. If about the drainage system to protect the foundation of your house, then these are just pipe from clay (pottery pipes) placed in the ground around the building at a short distance from it. The depth of the pipes can be the most different, but they must be directed towards the lowest ground level on your territory. Lay pipes with a diameter of less than 50 mm inappropriate. The pipes are covered with a denser layer of earth on top, and then, filled with sand. Water enters the pipes through the joints between them.
For storage and disposal of non -liquid household waste, cesspools are made, but to remove liquid waste, septic tanks. A septic tank can have one or more tanks. Practice has shown that a cesspool must be done, taking into account that 0.7 m3 is enough for one family member, that is, for a family of 4 people it is enough to have 2.8 m3 (1.2 m × 1.2 m × 2 m); The volume of one septic tank should provide a 3-multiple daily water consumption necessary for the family. The pit and septic tank is covered with wooden shields, which provide hatches closed with removable lids. The septic tanks should have ventilation pipes.

The walls of the cesspool and the septic tank are brick and they should be waterproof. To dispose of waste, you can use microorganisms (bacteria), which are on sale in the form of briquettes. For the first time, 3 tablespoons of concentrate are covered, and then monthly one spoon. The resulting humus can be used as fertilizer for plants.
The design of the septic tank is also quite simple. The input pipe of each tank should be located above the output, that is, the output pipe of the previous tank becomes the input for the next.
