Connection to the central water supply system - the main

Water supply

Bringing water into the house from the central water supply is a solution that not everyone can afford, because for the project it is necessary to have a water pipe running nearby. But on the other hand, if this option is possible, then the issue of permanent water supply is solved by itself, since this option is most preferable for a number of reasons. Consider which factors are more significant during installation work.

What materials will be required for the work

Regardless of how communications will be summed up, a certain list of materials is used during the works:

Trumpet	The main element of the system, the diameter of which depends on the project documentation and technical conditions. If earlier steel products were used everywhere, then nowadays they are replaced by a more progressive option - HDPE pipes, their characteristics are much better, and the price is much lower. Additional advantages include low weight, flexibility of elements and environmental safety.
Fitting	For the connection of individual sections, devices, branches and turns used special nodes. It is very simple to work with them, since all the elements are clamped by hand, and no special tools and equipment are required.
Connection node	If earlier, a tie-in to the central water supply was done exclusively with the help of electric welding, then with the advent of polypropylene pipes, the installation began to be done differently: now a special clamping coupling acts as a connecting unit, which is mounted on the required pipe section
Heater	With a shallow depth of pipe laying, they need additional warming. This can be done either with the help of a special pipe insulation, or by laying a heating cable that regulates the degree of heating depending on the surface temperature, that is, the temperature in different parts of the cable can be different
Materials for bedding	Many people forget about this factor, but the high-quality laying of pipes is impossible without the device of an even dense cushion of rubble of small fractions or gravel.

Tip! It is better to first consult with experts, they will tell you what is needed for the work and will help to conduct the most accurate calculations so as not to purchase unnecessary materials and components.

How should the workflow be organized

Immediately, we note that in order to arrange a central water supply system in a private house, it will be necessary to spend a lot of time not only on work, but also on drawing up documentation and coordinating it with the competent supervisory authorities. We begin the consideration with this part of the work.

Paperwork

In order to clarify the procedure for obtaining permits, the development of technical specifications and design of the project, you will need a whole instruction:

First of all, you should contact the water utility for the development of technical conditions for connection. To do this, you will need documents on the ownership of the land and the structure, a statement of the established form. The term for issuing an opinion is 1 month.
Ready-made specifications are provided to SES, which gives a conclusion about the possibility of tie-in communications. At the same time, design and estimate documentation is ordered by the competent organization, which provides all the main features of the system and reflects the location of each of the elements.
After the project is received, it must be registered with SES. At this design work can be considered complete.
Another important point that in no case can not be overlooked - coordination of the excavation works with public utilities. Only having the appropriate permission in hand, you can start work.

Tip! Some organizations that carry out the installation of water supply, provide this type of service, such as assistance in the preparation of documentation. You will pay a little more, but will be spared from numerous worries and trips to the authorities.

Only with a warrant in your hands, you can begin digging trenches for pipes

Work

We divide this process into separate stages to make it easier for you to understand their features:

Water supply of a private house from the central water supply involves the laying of the pipeline at a certain depth, which must be greater than the level of soil freezing.

This table indicates the depth of soil freezing in some regions depending on the type of soil.

If the soil is very complex or a highly located aquifer interferes with the desired level, the pipe can also be laid at a lesser depth. But in this case, you will need to use a heater, which is a segment of a certain diameter, another option is a heating cable, which can be laid both outside and inside the pipe.

Insulation for pipes allows you to protect them from the cold with a small depth of installation

Trenching can be carried out with the help of special equipment or manually. The second option is very time-consuming, but in some situations, when the entrance of equipment is difficult, it will be the only possible one.
The depth of the trench should be a little more than necessary, this is due to the fact that at the bottom you need to fill a gravel or crushed stone pillow. This provides additional support for pipes and reduces the load on them.
First of all, a pipe coupling is connected or a valve is inserted to connect the pipe. After that, you can lay the system to the house.
Entering the house is easier to implement in the following way: the pipe is laid under the foundation of the building or through it and displayed in any room at a distance of 1-2 meters from the outer wall. The vertical section is additionally thermally insulated to prevent the likelihood of freezing. At the entrance, a shut-off valve and a meter are placed, and further wiring is made throughout the house.

Approximately the input into the house looks like this, if the pipe is displayed with your own hands, make sure that its location is as convenient as possible.

When there is a winter water supply system in the country from the central water supply system, the pipe can be removed both inside and outside the building, this is due to the fact that in the summer a watering hose will join.
If the water pressure in the system is insufficient, then it is possible to solve the problem by installing pumping equipment, with its help the quality of the water supply will significantly improve.

In the photo: the connection of the pumping station to the central water supply system will not cause any particular difficulties, the instructions for the work are simple and clear.

Conclusion

Water supply from centralized systems is the best option, which is distinguished by simplicity and reliability. The video in this article will vividly show some of the above nuances and help to understand the topic even better.
