How deep to dig drains : recommendations for a system device

necessary pipes for sewage

previously used for this purpose only pipes of metal, but they are quite strongly affected by corrosion, because of what their life is not great.Today to address the problem have begun to use plastic.

additional plus to his longevity is that mounting is not necessary to carry out welding and construction equipment use, because the plastic pipe of the same diameter as the metal, on the order easier.

choosing pipes for the local sewage system, be aware that there are differences between the inner and outer sewage.

• Interior - is all the plumbing, which is located inside the house;
• Outdoor - pipe is placed in the street, as well as treatment facilities, storage.

distinguish the pipe can be in their coloring. example, pipes for street have brownish-orange color, and the pipes for the house - light gray. You should carefully study the information in the accompanying documents.Manufacturers describe in detail the scope of application of all types of pipes.You should also ask about the quality certificate that guarantees the purchase of quality goods.

depth and slope of the pipe laying

how deep to dig sewer outlet of the house?If you focus on SNIP standards, the system must go out to 30 cm higher than the freezing segment.At the same time it should not be less than 70 cm. In fact, given the conditions of our climate latitude, most pipes are laid at a distance from the surface of the soil to 50 cm. This is enough, if the top will not be arranged ground or roadway, which will be cleaned bysnow in the winter.

determine what will be the depth of laying the sewage system should take into account the factor that in most cases, it is planned that the waste water will go by gravity, thanks to the slope of the pipe.In this regard, it is necessary to determine the slope.

Note!If you plan not to waste system, and pumping, you do not necessarily bias.

norms suggest that the pipe diameter to 50 millimeters of slope should be at the rate of 0.03 meters per meter of pipe.Pipes up to 100 mm fall under the bias of 0.02 meters.In case of violation of these rules will care drains too fast or too slow.In both cases, it increases the chances of clogging, as will the settling of solid waste, which will prevent the flow of traffic.

Conclusions

mistakenly believe that the sewer installation depth must exceed a layer of frost.But it is not always possible.Therefore, the depth should be determined based on the specific situation.

Tip!To accurately calculate the depth, seek professional help.

From the above, we make the following conclusions:

• in average climatic zone depth of sewage will be equal to 0.5 meters.Further from home system should go under the slope recommended by SNIP;
• The fact that the tube be nipped by the frost, do not worry.Water Draining takes place at room temperature, so all the frost is washed off.Also, heat pipes as a result of biological processes in septic tanks.And when not in use the system, it is empty, because freezing and there is simply nothing.
