What should be the deviation of sewage

To date, every building hassewerage. If before the suburban areas were distinguished by the presence of a cesspool with a wooden house above it, now such structures are in the past. Fortunately, various options for sanitation allow a more civilized solution to the existing problem.

Anyone can install the sewage system. The main thing is to know several rules that will help to quickly cope with the task. Specialists note that the quality of the project (primarily) depends on the correct installation of sewer pipes. First of all, it is necessary to be able to calculate the slope of sewerage. The success of the work depends on the value of this parameter. Remember and that the slope of sewerage is not a constant value. The value of this indicator is calculated for each individual system, and sometimes for some of its sections. The value of the value itself depends on the velocity of the fluid.

The slope of the pipe must be made in the direction of the risersewage system, adhering to the optimum: from 4 to 7 cm / m. Too small a slope of the sewage system or too large threatens frequent clogging of the sewage system. To avoid such problems, it is necessary to make a bias within the limits of acceptable values, being guided by a specific case.

Be sure to keep in mind that plasticThe sewage system has the property of deforming or sagging, and this affects the slope of the sewer, reducing its value. Pay attention to the fact that in the new buildings over time, there is a draft of the foundation, which also significantly affects the amount of slope of the sewerage system. Specialists claim that the minimum slope of the sewage system (horizontal part of the sewerage) should not exceed 2.0 cm / m. Only at this value does the process of self-purification of waste water fully work.

With a long horizontal section of the sewage system(more than 10 meters), the slope should be increased to 4 cm / m. If this value is not adhered to, the probability of pipe clogging increases due to a lack of wastewater and a low flow rate.

Also experts recommend careful monitoringfor the number of turns and joints in the sewage system. You should be aware that any joint or turn is a potential leakage or clogging system.

There are other subtleties of the sewerage installation process:

• it is allowed to join several types of pipes;

• installation of plastic sewerage requires the use of lubricant;

• all joints must touch each other firmly;

• The horizontal section of the system should not be moved into the riser at a right angle;

• The access to the sewer riser is made easy.

Connection to the centralized systemsewerage is the easiest way to drain wastewater from any living space. But there are rare exceptions, when you have to resort to more complex methods of solving the problem (it is a question of installing a special pump, which is a "forced" device for removing drains from the house).

Typically, a pump for sewer installationOnly when the release from the house is below the place of accession to the centralized system. In this case, a special pressure system is required, consisting of three components: a storage well, a forced sewer pump and connecting pipes.

Consider the main advantages of the systemforced cleaning. First of all, the construction of forced sewerage does not take much time, energy and significantly saves the budget. Also, such systems do not require a constant angle of inclination of the pipes.
