Tapping into the city water supply network on your own, without the participation and approval of city services, is prohibited: the main networks are pressurized.
To ensure the authorized connection of drinking water from the city water supply network, it is necessary to perform a number of actions, following a certain procedure and the requirements of the law on water supply and sanitation.
Collection and preparation of documents
First of all, you should get a situational plan of the site with the application of all underground utilities. At the same time, the latest version is needed, which is available in the regional geodetic service — it is here that all surveys are handed over after the laying of the next section of underground networks. If the owner of a private house has such a plan, then it is important to make sure that it is suitable, and at the same time it is made on a scale of 1:500.
In addition to the situational plan, you will need to prepare:
- certificate of ownership of the site (or the right to use the land);
- application to the local water utility;
- technical conditions from the mountains. water utility.
The application is made in free form, with the following text:
“To connect a private house located at such and such an address to the city water supply network, I ask you to issue those. terms”.
Often, the water utility company issues ready-made application forms. You need to address your application to the head of the water utility, sign, date and list the attachments, these are copies of the situational plan and the title document for the land.
You will need to fill out a questionnaire — a standard document in which the user indicates how many tenants permanently reside, what dignity. those. appliances will be installed. This will help specialists determine the normative water intake for this residential building. Vodokanal specialists will register the application and explain when to come for ready technical services. conditions.
What does the federal law on water supply and sanitation say?
Those. conditions, in accordance with the federal law on water supply and sanitation, contain instructions:
- regarding the amount of permitted water withdrawal for a given water user;
- the number of the well from which you can connect to the highway;
- turnaround time.
Then, an application should be sent to the district SES with a request to issue an opinion on connection to the city water supply network. Obtaining an opinion from SES specialists is a signal that the first stage has been completed.
Drawing up project documentation
Designing the water supply of a residential building is a serious matter that people who are far from designing engineering networks should not undertake on their own. It is necessary to order a project to a specialized company that has the proper degree of accreditation, and most logically — to the project team of the same water utility. To the order, except for the situation, site plan and those. conditions, drawings of a residential building are also needed, and not only the plan of the first floor and basement, but also sections.
If you are far from designing engineering networks, order a project from a specialized company, and most logically, from the design team of a water utility.
The project consists of the following components:
- graphic part with an explanatory note;
- custom specification;
- estimates with a statement of resources.
If the owner of the mansion has a construction education, and the track is small, then it is quite possible to make a water supply project for a country house yourself:
- longitudinal profile with detailing of the entry points into the building and adjoining to the existing well.
Particular attention should be paid to the technology of excavation, highlighting the nodes of intersections with existing underground utilities, providing for their protection from damage. It is also necessary to draw up a bill of quantities.
It is important to understand what the slope should be, from what materials and what diameters it is best to take pipes, what shutoff valves should be used. With independent design of water supply systems, there will be no estimate. Project documentation is sent to the water utility for approval.
The finished project should also be registered with the SES, where the conclusion was previously issued. Now you can order a topographic survey, that is, a drawing of the area with specification of the distances between buildings, trees, fences up to the existing water well, from which water intake is allowed. The shooting is carried out by surveyors at a scale of 1:500, with the application of underground networks. Using this survey and the project, it is possible to fix the axis of the future route on the surface of the earth, earthworks will be carried out along this line.
Laying and connection works
The next most important stage is excavation, for which the City Administration receives an application — a form in 2 copies. to obtain a permit, and in the utilities, whose networks pass through the site, an order should be issued. Further, for earthworks, you need to contact a specialized company that has not only all permits for its activities, but also all the mechanisms that will be used. Such a company has gained experience in exactly how to organize and carry out such work: it will be necessary to call in place representatives of those city services whose communications fall into the zone of laying the water supply route, as well as comply with the requirements of external water supply networks, labor protection and safety.
If the length of the route is from a dozen or two meters, and at the same time the site is densely dotted
- underground pipelines,
- electrical cables,
- communication wires,
it is possible that the use of earth-moving equipment will be impossible. In this case, the work is carried out manually, in the presence of representatives of the relevant city services.
The finished trench should have the geometric parameters indicated in the project, and the walls of the house and the well should be bare, cleared of the ground and prepared for insertion. A tie-in into an existing water supply system is entitled to be performed only by employees of the water utility:
- they turn off the water supply to this well;
- connect the new pipeline to the main one, according to the water supply scheme of a private house.
The company that installs the pipe installs all design taps, plugs, valves, revisions, and other valves, as well as metering devices.
A tie-in into an existing water supply system is entitled to be performed only by employees of the water utility.
Now the network is almost ready, but specialists from the water utility operation service must accept the facility, checking it for compliance with the requirements of 416 FZ on water supply and sanitation, as well as SNiP, only after signing the act it will be possible to backfill the trench. The owner can already call a representative of the subscriber department to seal the meters.
The cost of the entire complex for external water supply depends on many factors, including the following:
- track length;
- pipe material;
- laying depth — the volume of excavation depends on it;
- local rates, etc.
The order of the numbers is:
- water supply project — 50 $;
- getting those. conditions — 40–50$;
- approvals — 120 $;
- the cost of pipes, water meter, components — 5–100 $.
- tie-in with a fee for connecting to the network — 15 — 500 $;
- excavator work — 5–100 $;
- network laying (in the complex) — 1.7 — 2.60$ per 1 pm.
Tariffs for water supply by region vary greatly, and in addition to the cost of the tie-in itself, they also charge a tariff rate for the length of the water supply network. Depending on the climate zone, it will also be necessary to provide for thermal insulation measures, and this applies to both entering the house and exiting the well, and the pipeline itself with water supply equipment. Backfilling of trenches is usually done with sand (partially or completely), and this is another plus to the total amount.
The issue price can be from 80 to 1200$.
Samples and cost of documents
In order for the local water supply network to be put into operation, it is necessary to prepare technical as-built documentation in accordance with the standards for water supply (external networks and structures). Such papers are prepared by engineering and technical staff of those companies that performed the work. Acts for hidden work — a special type of primary executive documents, certifying each operation, each layer, which, when performing the next technological construction work, will cease to be visible, that is, become hidden.
For acts of hidden work, there is a special form of forms where you need to enter the necessary information. The act of covert work on the excerpt of the trench should include information on how the excerpt was carried out — mechanized or manual, what soils the earth is represented by. It is necessary to indicate the parameters of the trench, if there are intersections, describe with which particular communications there was an intersection, what measures were taken to protect them.
The act of hidden work on sand filling gives an idea of the thickness of the bedding layer, which is important: sand is a bed for the pipeline. It is also important to demand such acts for hidden work on sp water supply:
- pipeline laying;
- hydraulic testing of the pipeline;
- backfilling the pipe with sand;
- backfilling of trenches.
In addition to these documents, the contractors are required to provide the customer with:
- executive survey of the water supply system — a scheme of water supply and sanitation;
- certificate for the installation of a metering device — a water meter.
But that’s not all: the SES service must flush the system and disinfect it, and then check the quality of the water by taking samples. Having issued a special act, the SES gives a signal to supply water to a private house. The presence of an act from the SES on washing and disinfection is a necessary attribute in the package of documents for supplying water to a private house.
The presence of an act from the SES on washing and disinfection is a necessary attribute in the package of documents for supplying water to a private house.
All these papers, upon completion of work, must be submitted to the city water supply metering service for technical examination for compliance with the project and all standards. After this procedure, a certificate of execution of those will be issued. conditions. To be able to supply water, it is necessary that the user’s relationship with the water utility for the operation of the water supply system of a private house be formalized. In the office of the municipal enterprise for water there are standard contracts, the owner of the house with a passport and a full package of papers goes there and signs a prepared contract for those. supervision in 2 copies.
Conducting water to a private house, crashing into the central water supply — the procedure is not particularly complicated, but associated with the execution of a large number of all sorts of documents. In order for everything to be done quickly and in compliance with the requirements of the federal law on water supply and sanitation, a specialized company with considerable experience and all permits should be involved in the performance of work.
