Internal sewage system - rules of the organization, specific

long been humanity is faced with the problem of waste water treatment.The story begins with the construction of sewer of ancient Rome.This is where there was the first interior drainage designed to remove products of human activity.These tanks are very similar to modern septic tanks, have to be periodically cleaned out.Weighty contrast - modern containers are fully sealed and prevent the pollution of groundwater and soil with harmful substances.

ancient Roman sewer, cesspool, different engineering complexity.When its construction was taken into account the terrain, and for lifting sewage on the platform used original pumping station.The width of the cloacal reached seven meters, forcing workers serving it to move on it in the boat.Even after drainage has appeared in all the other countries of the world.

In today's world the

problemwastewater helps to solve the installation of sewage treatment plants - local sewage, consisting of septic tanks and the filtration area.Cleaning systems of last generation can not only clean the drains to level position, but also to give the water produced a number of useful properties.Subsequently, it can be used for irrigation, washing of the tracks on the country site and other technical purposes.

Modern sewage system
no sewerage system the modern world it is difficult to even imagine

According SNIP drainage - internal network devices and pipelines that are responsible for allocating sewage from sanitary equipment use and other technological equipment.

Sewerage interior is designed to divert waste generated in the course of human life, in other words, its sanitary and domestic activities.In most cases, this gravity systems, i.e. a system in which the movement of fluids occurs waters influence of gravity.Moreover, it requires no additional energy.To eliminate the odor system is equipped with a hydraulic gate - siphon.

Tip: to domestic sewage should be provided free access of air.

Any internal drainage in a private house consists of the following mandatory parts:

  • container for receiving waste water;
  • installation for pumping or wastewater treatment;
  • pipelines;
  • collectors;
  • risers;
  • branch lines.

In suburban homes where the bathroom is located a significant distance from the riser assembly inside of sewer gravity type is not always possible.In such cases it is better to use a system consisting of a pump, a special container, and switch the pump with the help of which the waste water is carried out by a special tube.

What you need for installation of sewerage ↑

You must first make sure that pipes and fittings for domestic sewage have been purchased in sufficient quantities.It is necessary to buy the necessary return filters and air filter (if necessary for the project).

What is needed during installation:

  • hacksaw;
  • Bulgarian special disc designed for cutting pipes;
  • pipe diameter of 50 mm for the removal of waste water from the plumbing and appliances;
  • pipe diameter of 110 mm for the removal of waste water from toilets and bidets;
  • pipe diameter of 110 mm for the riser.

Tip: all the branch pipes are installed with a certain bias.For pipes with a diameter of 50 mm - the minimum slope 0.025, normal - 0,035.For pipes with a diameter of 110 mm - minimum slope 0.012, normal - 0.02.

mounting domestic sewage ↑

Mounting sewage - is a careful and a long process that requires compliance with certain sequence, carefully and accurately.From competent actions depends on performance of the system in the future and the quality of its use.Of course, to get really good results it is best to turn to professionals, but the interior drainage hands - is also possible.

Before starting work, be sure to familiarize yourself with SNIP: internal piping and sewerage.

installation and subsequent operation of the system requires full compliance with these rules.Internal drainage should be installed in accordance with the approved project.

Tip: If the project is made up yourself, be sure to show it to a specialist to further no problems.If the project is approved, or, better yet, made by trained staff, you can easily buy all the necessary material.

Set risers ↑

mounting domestic sewage should begin with the installation of risers.First, do the markup according to pre-developed plan, and then proceed to install the pipeline.Installing risers, try to comply fully with its vertical position and to avoid distortions and fractures in places jointing pipes.The pipeline should be done by laying the pipe sockets up from the basement, at the same time arranging the audit.

What is auditing?It is fitting (tee), which provides free access to the places of the pipeline, which may cause congestion.As a rule, the audit established at each site where the pipeline forms an angle in the beginning of each riser in the room and at the end of domestic sewage.

At long linear pipe fittings at a distance of no more than 30 meters apart.If the riser is planned to be sewn, when installing the audit should take care of the inspection covers, intended for maintenance of the pipeline.

Each sewage risers necessarily end ventilated overlooking the ventilated attic or on the roof of the house in the form of an individual ventilation duct.For security purposes is strictly forbidden to display the ventilation of the sewer system in the chimney of the building network.Simultaneously with risers mounted horizontal branch lines on all floors of the building.

Important: categorically not be allowed in places of location of the sockets pass through various constructions, for example, overlap.

Installation flowlines ↑

After installing risers are connecting them flowlines from toilets, baths and other sanitary equipment.For this purpose, cast iron or plastic pipes for domestic sewage, and their diameter must be identical to the diameter of the outputs of sanitary devices.

Tip: length of the discharge pipe should be less than ten meters, and the angle of inclination must be such as to not impede the free movement of waste to the riser.This sockets are installed against the flow of wastewater.

When installing sewer pipes Machining pipes and tubes produced by manual hacksaw or melkozubnymi wood.Cutting is carried out perpendicular to the axial section of the pipe.Burrs formed during sawing, be sure to remove and place chamfer coarse file.But the fittings and corners is strictly forbidden to cut and process.If necessary, all the elements of sewage treated with special grease or soapy water, the use of engine oil and its analogues is strictly prohibited.

with technological rules of domestic sewage will introduce video.

If the installation of internal sewage system will be carried out taking into account the SNIP and all rules of installation, you will be able to achieve its long-term operation without fanfare, frequent blockages that lead to exhausting drain cleaning, replacement of deformed pipes and other troubles.
