What is the depth of laying water pipes is optimal

Water supply

During the construction of a new house or when supplying water to an existing building, there is always a question before builders and owners on the depth of installation of water pipes. Competent calculation will ensure year-round operation of the system. The expression - the more, the better it will not always be correct in this case. Why spend extra money and effort to dig a deep trench?

In addition, there are often situations where the ground does not allow you to do it yourself or the surface water is located fairly close. In addition, when it is necessary to carry out repairs, as well as in the event of a change in the water supply system, difficulties may arise.

At what depth to bury the water pipe on a country site

What affects the depth

The closer to the surface the water pipe, the faster the water in it will freeze.

From this and other factors it can be concluded that the depth of the trench for the pipeline depends on:

  • temperature in winter;
  • soil characteristics, its ability to freeze;
  • pipeline system temperatures;
  • layer of cover plants on the site;
  • amount of solar time, precipitation, including snow;
  • water supply time;
  • remoteness of surface water.
The depth of the water pipe depends on many factors.

We considered only the main factors that allow us to determine how deeply to bury the cold water pipe.

It should be noted that:

  • this distance should be sufficient so that in cold weather the temperature does not fall below 0 ° C;
  • at the same time, during the hot period of the year, it should not heat up quite strongly.

In fact, it is necessary to find some kind of balance to ensure correct and reliable operation of the entire system. This can be achieved only taking into account all the parameters of influence.

Tip: you can use modern devices, with which you can make the necessary calculations to obtain an adequate result to ensure the smooth operation of the system.

Standard indicators

In order not to search for a long time, you need to take the SNiPs developed and find the parameters of interest to us. These data are obtained experimentally, therefore, they are of real value to the home master.

They can be reduced to the fact that any laying of water pipes should take place at a level that is below the possible soil freezing by at least 500 mm.

Depth of laying water pipes in different regions of the country

Tip: in the building codes of interest to us, the data are summarized in special tables for each region of the country.

For example, for the Moscow region, the indicators of the depth of freezing depend on the type of soil consisting of:

  • coarse elements parameter is 1.9 m;
  • loam and clay - 1.3 m;
  • gravel - 1.7 m;
  • sandy loam and sand - 1.6 m.

At the same time, for the region of Siberia, everything will be much more complicated.

Depth of water supply by region

The result about the SNiP can be done the following, taking into account the depth of freezing of the soil and the overall rate for laying the pipeline, it can be said for:

  • southern regions depth is 0.5-1.2 m;
  • middle lane - 1-2 m;
  • northern regions - 2-3.5 m.

The calculation is given without regard to local peculiarities, which must also be taken into account.

The depth of the laying of water pipes in the northern regions is costly

The instruction prescribes that the minimum depth of the pipeline should be such a distance that is able to protect the structure from mechanical damage associated with transport or other loads. Therefore, it is always indicated 500 mm from the surface, although for each territory it is best to carry out its own measurements.

Practical recommendations

The laying of water pipes in a suburban area is an important process, which further affects the comfort of life. But, if we now more or less understand the depth at which water supply pipes are laid, it’s time to talk about other useful points for carrying it out and connecting it to the main line.

Crane We recommend to find a good place for the main crane. This may be a well, which must be laid out material that provides access to it at any time. When placing the valve constantly above ground level, it should be insulated.
Pipeline
  1. When using metal pipes, be sure to ensure that in the event of a valve failure it could be easily repaired. We recommend that you periodically take preventive measures so that the problem does not take you by surprise.
  2. Any metal, even a stainless steel, eventually becomes covered with corrosion. Use special materials to increase their rust resistance.
  3. Such problems will not be with plastic pipe products, the price of which is also lower, but in this case it is necessary to take care of the reliability of the connections.
Plan When all work is completed, draw a diagram in which you specify the depth of the water pipes and other characteristics of the water supply system. In the future, this will help simplify the solution of problems encountered during operation.

Conclusion

From the above, one can conclude that there is no definite answer to how deep the pipeline is to be laid. Each region has its own characteristics of the soil, as well as other factors that can directly affect this parameter.

All this must be taken into account for the proper installation of a water pipe in order to ensure its long service life. The video in this article will provide an opportunity to find additional information on the above topic.
