According to the rules for placing cesspools on a site, it is necessary to take into account the depth, volume of the tank, as well as the distance to residential and farm buildings, drinking wells, water pipes, green spaces. It is recommended to coordinate the installation site with the sanitary authorities and water utility.

The sewage treatment system is aimed at the processing of liquid waste by mechanical, biological and chemical methods, so that the output is ecologically safe water. It can be discharged into natural reservoirs or used again for technical and domestic purposes.

Permissible concentrations of pollutants in wastewater are determined by sanitary standards. The analysis is necessary for industrial enterprises and private estates in bulk waste dumping.

The gutter system can be made of plastic, galvanized steel, aluminum, as well as metals coated with polymers. For the system to work properly, it is necessary to observe some installation rules and take into account the physical properties of materials during thermal expansion.

Types of sewerage for its intended purpose: household, storm and industrial. According to localization it is divided into internal and external with general alloy, separate or semi-separate water disposal. In private estates, autonomous sewers are usually used: cesspools, dry closets, septic tanks.

Cast-iron sewer pipes are used in urban highways. They are strong, not susceptible to corrosion, resistant to temperature extremes, and durable. The cost of such a system is several times more expensive than plastic. Installation is rather complicated due to weight and tightness.

Insulation of external sewage pipes is necessary to prevent the formation of ice plugs and pipe rupture in the winter. Use special materials or an electric self-regulating cable. There is a pipe sandwich with a ready-made insulation on sale.

Flexible corrugated pipes for plastic sewage are popular due to the ease of transportation and installation, impact resistance and resistance to negative external influences. Depending on climatic conditions and soil quality, light, heavy or extra heavy products are used.

The red sewer pipe is designed for an external drainage system. It is more durable, withstands temperature changes, does not deform. Material, diameter and thickness are selected depending on the operating conditions.

Viewing wells are used along the entire sewer line. They are installed so that at any time it is possible to track the condition of the pipes. The most vulnerable areas - turns, pipe transitions from a smaller to a larger diameter and vice versa, branches - should be visible through the inspected well.

Installation of drainpipes is necessary to protect the building from flooding and decay. You can purchase a ready-made set of metal or plastic, or make a drain yourself from sewer pipes, galvanized steel sheets or plastic bottles.
