The act of spilling external storm drainage. External sewerage spill report form

The quality of installed sewage systems in a country house and beyond is checked at all levels. First of all, all building codes and requirements must be observed. Then the installation is supervised. And at the end, tests are carried out and a sewerage spill report is drawn up, a sample of which can be found on the Internet.

What is checked and who checks

In order to check the functionality, the following is carried out:

• internal system testing;
• tightness;
• functionality of wells;
• storm sewer system.

Internal sewerage consists of plumbing fixtures, which include household appliances with water drainage; all internal pipes, as well as the central pipeline with the drain pipe.

Internal sewage system

In turn, the external sewerage system consists of pipelines directed from the house to the septic tank, wells and their connections, treatment facilities, as well as drains for storms and rain.

To inspect the sewerage system, a special commission is assembled from representatives of the following companies:

• who compiled the project and is responsible for all calculations and drawings;
• carried out on-site research and was responsible for information on the climate and environmental situation;
• laying the sewer network and is responsible for the quality of its work, as well as compliance with current standards;
• ordering and supervising all construction and responsible for quality checks when putting the system into operation.

The liability of all organizations is strictly limited to the scope of the work they perform. After the inspection, a sewerage spill report is drawn up, the form of which the representatives usually carry with them.

If any errors or shortcomings are discovered, the guilty company is held accountable depending on the severity of the violations identified.

How to check internal sewerage

All tests are carried out strictly according to the prescribed sanitary standards and rules called “Sewerage. External networks and structures.” According to them, it is necessary to check:

• compliance with the project;
• the strength of all joints and connections;
• correct installation of plumbing fixtures and flushing parts;
• strict verticality of risers.

The check is carried out visually. Each part in it must be located in the place in which it is calculated according to the plan or provided for in the drawing.

All equipment must be perfectly clean and washed. During inspection, check that there is no damage on them in the form of cracks, chips, and so on. All kinds of distortions are also excluded. Deflections during installation are unacceptable.

The verticality of the risers can be easily checked using the plumb line method.

The pipeline is checked in two ways:

• pneumatic - air;
• hydraulic - water.

In this case, the system can be checked with water only if the surrounding temperature is at least five degrees Celsius.

If there is more than one floor, each of them is checked separately. Plugs are placed on the inspection in order to separate it from the rest of the sewer system.

The following is checked in the pipeline:

• are there any blockages in the pipes or is there any construction debris left - if there is any, flushing is carried out;
• horizontal parts are tested for leakage - to do this, open ¾ of the drain pipes or more, fill them completely with water and leave for ten minutes (if the system is working properly, no leaks should be detected);
• a pressure of 0.08 MPa is applied to the vertical sections and maintained for fifteen to twenty minutes.

If leaky connections are found in one or more areas, the problem is corrected and the tests are carried out again.

How to check external sewerage

In this part of the sewerage system, tests are mainly carried out using the hydraulic method. They consist of:

• testing the tightness of the pipe in the same way as in the previous method;
• checking the presence of the required level of pipeline slope;
• checking wells and all other equipment;
• checking the operation of storm drains.

To check the existing slope for compliance with the standards, use a level. To test the water pressure system, water must be supplied under pressure, which is provided for in the design documentation. If its value at the input and output remains the same, then this test can be considered passed.

The tightness of wells is checked in different ways depending on the waterproofing that is installed in them:

• for internal insulation, check the leakage volume;
• with external - on the contrary, the level of inflow.

But in any case, for this test the well is filled with water to the required level.

Storm drains are tested as follows:

• a plug is installed at the drain outlet;
• fill it with water as much as possible;
• withstand from ten minutes if the pipes are made of metal, and from twenty minutes if they are made of plastic.

If the level remains the same as from the very beginning, then the pipe is ready for use.

It should be taken into account that plastic pipes can only be checked one day after the last joint is sealed.

Biotank type septic tank system

The sewer system must be checked before it is put into operation. This will help to timely check all hidden defects during construction and correct them with minimal losses. It is advisable to check all the work before the final finishing is done and the trench is buried outside the house. Based on the results of the inspection, a report is drawn up for testing the external sewerage system for spillage, a sample of which is contained in the building codes and regulations.

In addition to this document, in order to accept the work carried out and obtain one hundred percent confidence in its compliance with all existing building codes, you also need to obtain all drawings with signatures from those representatives of the organizations that were involved in the work and were responsible for its implementation.

After receiving all the documents in hand, you can draw up an acceptance certificate for the sewerage system and start using it.

After completing the installation work of internal sewerage systems and drains, the installation organization must carry out their tests and draw up a report in accordance with Appendix “D” “Internal sanitary systems of the building” (updated edition of SNiP 3.05.01-85). These tests must be carried out by pouring water by simultaneously opening 75% of the sanitary fixtures connected to the area being tested. The test method gives rise to the “everyday” name of the act – sewer spill act or sewer spill act. However, the name of the act according to the regulatory documentation is as follows - test report for internal sewerage and drainage systems.

We have figured out the correct name of the act and its purpose. Now let’s take a closer look at the form of the test report for internal sewerage and drainage systems and the method of filling it.

First, fill in the name of the system on which the tests were carried out. We take the name of the system from the design documentation. For example, this could be “domestic sewerage K1”.

Next, you need to fill in the name of the capital construction project. There is nothing complicated here. We take information about the name from the design documentation or construction permit. After this, we enter information about the city in which the capital construction project is located and the date of the tests.

The block in which data about the commission that conducted the tests is entered includes the following information: the name of the customer’s organizations, the general contractor, the installation (construction) organization, as well as the positions, initials and surnames of representatives of these organizations.

In paragraph 1 of the test report for internal sewerage and drainage systems, data (name) is entered on the design organization, design documentation code, drawing numbers in accordance with which installation work was performed.

In paragraph 2 we indicate the number of simultaneously open sanitary fixtures and the time during which the tests were carried out. Sanitary fixtures include bathtubs, washbasins, shower trays, drains, bidets, toilets, closet bowls, urinals, sinks, sinks, and drains. During tests in accordance with the rules, at least 75% of the sanitary fixtures connected to the tested area must be open simultaneously.

Clause 3 of the sewerage testing report includes data on defects identified during testing. If no defects are found, then we make a note that during inspection during testing, no leaks were found through the walls of the pipelines and joints.

Based on the results of the tests, a decision is made by the commission, which is recorded in the end of the act. As a rule, this is a template paragraph, which is only supplemented with data about the name of the tested system.

After completion of the tests, the act of spilling is signed by all members of the commission. Changing the form of the act or deviating from it is not allowed.

After completing all installation work on the sewerage system, it is necessary to test the communication using the spill method. This is done in order to identify defects in the installation of drains, channels, sewer outlets, internal drainage systems, etc. The result of the inspection is included in the act, the form of which is approved by SNiP (Appendix “D” SP 73.13330.2012 “Internal sanitary systems of the building” - updated version of SNiP 3.05.01-85). A similar document in everyday life is called “Act of spillage of the sewer system”; in narrow circles of professionals, the same document has the official name “Act of testing of internal sewerage systems and drains”.

This stage of construction of sewerage communications is mandatory and cannot be cancelled. The verification activities themselves are carried out using the full spill method, provided that at least 75% of the drain holes are opened in a single period of time.

Important: it is possible to put a bunch of sewer outlets into operation only on the basis of an act of carrying out all the proper manipulations and obtaining a positive result.

Below in the material there is an example of how to correctly fill out the document.

To identify defects in the operation of the sewerage system, a series of tests are carried out, which includes:

• Checking the operation of the internal part of the communication using the spill method;
• Full check of the tightness of all pipeline joints along its entire length;
• Identification of possible defects in the operation of all sewerage wells (inspection, rotary, inspection, etc.);
• Storm sewer testing.

Correctness of filling out the act point by point

The first entry that is made in the act is the name of the communication that will be tested in the presence of a special commission. The name without distortion can be rewritten from the project documentation. This could be a storm sewer or a domestic sewer.

The next paragraph of the sewerage system test report should include detailed information about the facility on which the sewerage system is installed. The name of the object, its location address and area are also taken from the project documentation. The date of testing is also indicated here.

Persons - members of the commission

In a separate paragraph in the inspection report for external or internal sewerage, it is necessary to record all the data about the members of the commission. These are:

• Representatives from the customer organization.
• Representatives from the general contractor. These persons are responsible for the correct installation of drains in case they do not comply with technical and operational standards during a spill.
• Members of the design organization who were involved in the development of the communication project being tested.
• A representative of a company or organization that was engaged in soil research at the site for the installation of external or internal communications. This office bears full responsibility for the inconsistency of the data received on the site regarding environmental and climatic conditions for the construction of sewer communications.

Thus, in the paragraph of the test acceptance certificate, it is necessary to include all the initials and surnames of the commission members with their signatures.

Filling out the act point by point

• Paragraph 1 will contain detailed information about the company that designed the drainage system. The name of the code in which all project documentation was compiled is also included here. In addition, in the first paragraph of the document on testing the sewage system by pouring internal and external communications, it is necessary to enter all the numbers of the drawings that were used during installation for each drainage section.
• Clause 2 of the above-mentioned test report must contain accurate information about the number of simultaneously open sanitary points and the period of time during which the tests took place using the full pressure flow method. According to SNiP, sanitary points include toilets, sinks, bathtubs, showers, bidets, urinals, drains, etc.

Important: at the time of sewer testing, according to SNiP regulations, at least 75% of sanitary points must be open at the same time at the site.

• Clause 3 of the completed report is intended for records of possible violations in the operation of the system. That is, about the occurrence of leaks, stagnation, blockages, etc. If this was not detected at the time of checking the communication, then in paragraph 3 an entry is made that no leaks or other unauthorized deviations in the operation of the sewer system were detected at the time of the test.
• Last section- this is a decision of the commission, which allows or does not allow the drain to be put into operation depending on the test result obtained.

Important: the signatures of all commission members are required at the bottom of the document. Otherwise, the act will not be considered valid under the law. In addition, any deviations from the form of the act and the principles of its completion are unacceptable.

If obvious deficiencies are found in the communication work, indicating the negligent attitude of the contractor or all organizations accompanying his work, then the organization responsible for the deficiency, according to the law, bears administrative, disciplinary or criminal liability (depending on the identified defect).

Conducting tests: basic principles

The internal system includes the following objects:

• All plumbing points and household appliances that drain water;
• The entire pipeline connected to the central manifold;
• Central sewer riser.

The external test system includes:

• A pipeline placed outside a building to transport wastewater to a point of accumulation or disposal;
• All inspection and rotary wells;
• Storm drainage channels.

In order for the testing to pass efficiently and fully reflect the condition and performance of the sewer communication, it is necessary to adhere to the basic rules:

• Thus, all plumbing points must be cleared of possible construction and natural debris before carrying out work;
• It is worth checking all points for cracks, chips and other damage;
• It is important to monitor the evenness of all straight sections of the network. There should be no deflections or bends;
• All vertical risers must be checked using a plumb line;
• To check the pipeline, you can use either a hydraulic method (spill method) or a pneumatic method (pumping the system with air);
• Important: drainage of sewer lines can only be carried out if the air temperature around does not fall below +5 degrees. If the outside temperature is below the specified parameter, then a pneumatic testing method is used.
• It is worth conducting a separate communication check for each floor of the building. To do this, audit plugs are installed on all other floors.

Important: it is worth knowing that sewerage tests are carried out before all trenches of the external system are buried.

The block in which data about the commission that conducted the tests is entered includes the following information: the name of the customer’s organizations, the general contractor, the installation (construction) organization, as well as the positions, initials and surnames of representatives of these organizations. In paragraph 1 of the test report for internal sewerage and drainage systems, data (name) is entered on the design organization, design documentation code, drawing numbers in accordance with which installation work was performed. In paragraph 2 we indicate the number of simultaneously open sanitary fixtures and the time during which the tests were carried out. Sanitary fixtures include bathtubs, washbasins, shower trays, drains, bidets, toilets, closet bowls, urinals, sinks, sinks, and drains. During tests in accordance with the rules, at least 75% of the sanitary fixtures connected to the tested area must be open simultaneously.

Testing sewerage for spillage and snip standards

If the temperature is lower, a pneumatic leak test of pipes and connections is carried out (compressed air). The integrity of the riser, sometimes of external sections of the pipeline, is also determined by air.
We will use the pneumatic testing method to assess the performance of a pressure sewerage system, when wastewater is forced out, under pressure created by pumping equipment. The location of installed plumbing fixtures and its compliance with project documentation is determined visually.

The height of the receiver of each device, the correct connection of the toilet drain, siphons of the washbasin, bathtub, sink, etc. are objectively assessed and reflected in the report. The condition of the plumbing fixtures themselves is also visually assessed.

They must be free of visible dirt and mechanical damage.

Sewer flushing. testing sewerage for spillage and snip standards

• sewer risers;
• outgoing pipe.

In the external part of the sewer system, sections of the pipeline (between cleaning and auxiliary equipment) are tested for leaks, as well as: Advertising

• operability of wells, tightness and slope of the pipeline;
• condition of treatment or storage facilities (reservoirs);
• storm sewer.

Parties participating in the inspection Each of the representatives of the parties participating in the tests and signing the final inspection report is responsible for inaccuracies and shortcomings. If we are talking about more or less large-scale construction, where several organizations are involved, not counting the customer, testing of sewer systems is carried out by everyone they, after which the results are documented in the appropriate inspection report.

Video: Testing the sewer system for leaks Responsibility for the performance of the sewer system The check is carried out by a commission consisting of:

1. representatives of the company that compiled the project, area of ​​responsibility - carrying out calculations and drawing up drawings;
2. the company that carried out the research on the ground - the correctness of the given climatic conditions and environmental conditions;
3. the organization that carried out the installation of the sewer system - quality of installation, compliance with standards;
4. the customer – the correctness of the inspection when putting the sewer network into operation.

Each commission member has a clearly defined area of ​​responsibility. After the inspection, an acceptance certificate is drawn up, which is signed by all members of the commission.

External sewerage test

The external system and internal network are checked in various ways, regulated by the fundamental document of builders - SNiP. How to test the tightness of pipes and sewer connections by pouring, filling, and other methods, and what data is entered, if necessary, into the inspection report, you will learn by reading the article.

Sewerage units and systems to be tested The entire sewerage system in each building is divided into an internal sewage disposal network and an external sewerage system. The entire sewerage system in each building is divided into an internal wastewater disposal network and an external sewerage system.

Sewer test report for spillage

Acceptance tests The inspection begins after a concrete pipeline or well has stood filled with water for 72 hours, and pipelines and wells made from other materials - 24 hours. The pipeline is considered suitable for operation if the volume of added water does not exceed the permissible inflow .

The permissible influx of water onto a 10-meter section of the pipeline, during a test of 30 minutes, for polymer pipes is determined by the formula: q = 0.06 + 0.01D, where:

• D – outer ∅ of the pipeline, measured in decimeters;
• q – permissible volume of added water, in liters.

The sewer system must be tested before it is put into operation. The test allows you to detect a leak in a timely manner and correct it at the initial stage.

How to test a finished sewerage system

The test method gives rise to the “everyday” name of the act – sewer spill act or sewer spill act. However, the name of the act, according to the regulatory documentation, is as follows: an act of testing internal sewerage and drainage systems.

We have figured out the correct name of the act and its purpose. Now let’s take a closer look at the form of the test report for internal sewerage and drainage systems and the method of filling it.

First, fill in the name of the system on which the tests were carried out. We take the name of the system from the design documentation. For example, this could be “domestic sewerage K1”.
After this, we enter information about the city in which the capital construction project is located and the date of the tests.

Preliminary tests of gravity sewer networks are carried out pneumatically before the final filling of the trench. A test pressure of compressed air equal to 0.05 MPa is maintained in the pipeline for 15 minutes.

At the same time, the joints are inspected and leaks are detected by the sound of leaking air, by bubbles formed in places where air leaks through butt joints coated with soap emulsion. The final pneumatic tests are carried out when the groundwater level above the pipe in the middle of the tested pipeline is less than 2.5 m.
Final pneumatic tests are carried out on sections 20-100 m long, and the difference between the highest and lowest points of the pipeline should not exceed 2.5 m. Pneumatic tests are carried out 48 hours after backfilling the pipeline. The test excess pressure of compressed air is indicated in Table 5.

Testing of external sewerage networks

Preliminary tests Acceptance tests Pneumatic tests Preliminary tests Hydrostatic pressure in the pipeline during its preliminary testing must be created by filling the riser installed at its upper point with water, or by filling the upper well with water, if the latter is to be tested. In this case, the value of hydrostatic pressure at the top point of the pipeline is determined by the amount of excess of the water level in the riser or well above the pipeline shelyga or above the groundwater horizon, if the latter is located above the shelyga. The magnitude of hydrostatic pressure in the pipeline during testing must be indicated in the working documentation. For pipelines laid from free-flow concrete, reinforced concrete and ceramic pipes, this value, as a rule, should be equal to 0.04 MPa (0.4 kgf/cm2).

Testing of external network Testing of external sewerage is carried out mainly by hydraulic method. Work performed:

• pipeline slope control;
• the pipeline is tested for leaks;
• examination of wells and other equipment.

The slope level of the external sewer is checked by level.

The test is carried out between wells, in stages, each section is disconnected from the system using a plug. Test scheme for non-pressure systems::

• checking pipes for blockages and debris from construction, and flushing if necessary;
• spill test - a section of the system is filled with water; if no leaks are detected within 10 minutes, the test is passed.

Water is supplied to the pressure sewer under pressure. If the pressure at the inlet and outlet of the pipe is the same, the test is also considered passed.

The check includes:

• testing the pipeline for leaks (carried out as described above. For testing, sections of pipes located between wells or other elements of the system are taken);
• checking the pipeline slope level;
• testing of wells and other equipment;
• checking the performance of storm drains.

A level is used to check the level of pipe laying required for a gravity sewer system.

If a pressure sewer test is being carried out, then water must be supplied to the pipeline system at the pressure specified in the design documents. The test of pressure sewerage pipelines is considered successfully completed if the pressure value in the flow into the network and at the exit from it is the same.

Sewage system test report

Testing of the internal sewage system should be carried out by passing water by opening three quarters of all sanitary fixtures at the same time. All water fittings must be directly connected to the section of the pipeline on which the tests are being carried out for the entire time necessary for its inspection.

The system is considered to have passed the test, provided that the inspection did not reveal the presence of leaks through connection points, seals and pipeline walls.

Sewerage outlet pipelines laid in the ground and in channels under ceilings are tested until they are closed by filling them with water to the floor level of the 1st floor of the building.

When testing sections of sewerage pipelines that are hidden during further work, water is spilled until they are closed and an inspection report for the hidden work is drawn up.

Testing of the internal storm drainage system is carried out by filling it with water to the level of the highest level of the drainage funnel. The duration of the test is about ten minutes. The drainage system is considered to have successfully passed the test if during the inspection no traces of leakage were revealed and the liquid level in the risers did not decrease.

Sewer spill

If you have had a sewerage emergency caused by damage to the pipeline structure and, after calling the appropriate service, the integrity of the system has been restored by replacing part of the pipeline, the first thing you should check is the tightness of your system. This indicator is fundamental when it comes to the service life of the sewer system. Not only old sewers after reconstruction, but also new systems before putting them into operation are subject to leak testing. If your drain system is not sealed, this will guarantee trouble for the sewer owner and his immediate neighbors.

We perform an act of drainage of sewerage

In order to avoid possible negative consequences, the sewer system must undergo a series of reliability tests, including the act of spilling sewerage. The presence of a spill certificate indicates the serviceability, suitability and tightness of the system.

And before the act is drawn up, the sewerage system is subjected to hydraulic testing by pouring pipes. During a spill, water is released through the area being checked and about 75% of all plumbing fixtures that are connected to the area being checked by the spill are turned off. There is no exact time for passing the strait, but this is not so important. The main task of flushing is to inspect the pipes of the test section to be able to confirm their reliability and tightness. The spill test will be considered passed if no leaks were detected during or after the spill. In this case, you can draw up and sign the corresponding document.

For sections of the sewer system that are subject to complete closure with earth or building structures, a spill test and a spill report are drawn up before free access to the pipes is closed, and often a spill report must be drawn up separately for each of these sections.

In addition to the sewerage certificate, in order to accept the work performed and know that it complies with all modern building codes, it is necessary to obtain construction drawings with signatures of company representatives responsible for the work and an inspection report for hidden work.

Only by submitting a sewerage spillage certificate with the specified degree of tightness of the system, test results, drawings and a certificate of inspection of hidden work, only then can a sewerage system acceptance certificate be drawn up.

TESTING AND OPERATION OF INTERNAL SEWERAGE

TESTING OF INTERNAL SEWERAGE

Testing of the installed internal sewage system is carried out in the presence of a commission consisting of representatives:

a) customer

b) general contractor (construction organization)

c) subcontractor (installation organization).

The following system indicators are checked:

1) Drain from appliances.

2) The system must correspond to the project in terms of dimensions, elevations, pipe diameters, and their material.

4) There should be no leaks or leaks on the pipelines.

Testing of domestic sewage system K1 is carried out by pouring water from 75% of the water taps in the building. The system must provide normal drainage. If the system has successfully passed the test, then a final test report for the internal sewage system is drawn up in the form of Appendix 4 of SNiP 3.05.01-85, which is signed by representatives of the above-mentioned commission.

The K2 rainwater drainage test is carried out by filling the drainage pipe with water up to the roof level. Within 10 minutes, the riser should not leak in the places where it is installed (staircases, corridors).

Testing of industrial sewage system K3 is carried out by pouring water from 75% of water taps in an industrial building. In addition, the efficiency of treatment facilities and pumps at pumping stations is checked.

After testing, the internal sewage system is ready to be transferred for operation.
