A multi-stage wastewater treatment system includes mechanical, biological, physico-chemical and disinfecting stages. The output is purified water, which theoretically can be drunk, but it is recommended to pre-boil or use home filters.

The waste-dissolving agent for country toilets and cesspools should be selected depending on the composition of the effluent, the type of septic tank and the main goals of the owners. If you plan to use recycled waste as fertilizer, bacterial formulations are needed.

Before flushing the sewer pipes, you need to determine the place and cause of the blockage. Small shallow plugs are removed using special liquid products. Mechanical blockages in the toilet are punched with a plunger or plumbing cable. Complex deep blockages will help clean professionals with a hydraulic installation.

The device of autonomous sewage in a private house with your own hands requires a lot of labor and a thorough approach to design and preparation. It is necessary to determine the location of the septic tank, taking into account the norms of the sanitary and epidemiological station, calculate the depth, take into account the amount of water consumed.

The layout of the sewer pipes in a private house provides uninterrupted functionality of the mains. It is important to consider the location of plumbing units, their quantity, water consumption per person. Installation errors will lead to blockages and leaks.

Sand traps for storm sewers trap 80% of large debris, suspensions, sand. Water is purified, the drainage pipes do not clog. By design, devices are vertical, horizontal, tangential, aerated. In household plots, horizontal sand traps are usually used.

Methods of connecting cast iron and plastic sewer pipes: flange, fitting, with rubber gaskets, caulking with tow or linen, silicone sealing. The choice depends on the condition of the connecting zone and the line itself, as well as on the available materials and tools.

A water trap is required to block unpleasant odors and water shocks. It is, as a rule, a curved piece of pipe in which water stands. During installation, it is necessary to select the correct diameter and check the system for leaks.

The dimensions of the sewer rings of reinforced concrete products are selected depending on the area of ​​the site and the amount of water consumed, as well as on the type of sewer system. For a small cottage, products 90 cm high and 1 m in diameter are suitable.

The distance between the water supply and sewerage vertically and horizontally is regulated by normative documents of SNiP. All distances must be observed to avoid contamination of drinking water with sewage. Also takes into account the location of buildings, roads, wells, trees.
