Manufacturing of sewerage for a bath in the country Manufacturing of sewerage for a bath in the country

Convenient and high-quality sewerage for a bath in the country is the result of a competent planning the design and understanding where to place the drain in the bath room, and what else cannot be done under any circumstances. Successful designs, which are discussed in the article, will be an excellent help in laying sewers.

The device of the bath sewerage

Almost all well-planned and self-built steam rooms behave like a living organism. The sewage system is the dirtiest part of the bath, especially if the building has showers or a toilet for regular use.

For this reason, it is better not to do the simplest drainage by gravity into the nearest ditch, but try to build a classic scheme, where there will be aroma blocking and dirty water backflow.

Depending on the size of the bath, location, geology of the site and distance from civilization, a system for drainage of wastewater is made by different methods:

  • Simple drainage by gravity into the nearest ditch / underground receiver.
  • Separate sewerage system with an intermediate tank for collecting contaminated water.
  • Standard scheme for draining wastewater from a bath to a centralized sewerage system.

Masters divide systems into pressure (i.e.

pumping) and gravity systems. The only difference is that in the first case, the used water is discharged beyond the boundaries of the site by a special submersible pump, and in the second, everything flows down by gravity. Used water is absorbed into the ground with minimal harm to the environment.

Good advice! For an ordinary user, the method of water drainage does not matter, and therefore, when choosing a system, pay attention to the thoroughness of the functioning of the sewage system under all weather conditions and the absence of third-party aromas.

More expensive is not always better, and therefore, when choosing an expensive project for a bath with pumped sewerage, you need to know exactly why the pressure circuit cannot be replaced with a drain, which is cheaper.

Which system is better

The answer to the question is clear even without comments. Sewerage is better for your bath, in which:

Naturally, half of the factors that affect the choice of the sewerage scheme are the arrangement of the bath room and the location.

For example, for a freestanding summer cottage steam room, the best method would be a self-made drain pit. If the bath box is built into a residential cottage, which is built in a holiday village, then it is worth looking for a method that is safer for the environment.


In a dacha settlement with dense development, no one will give the opportunity to equip a sewage system with a cesspool type. No matter how they are equipped, an unpleasant aroma will still be present. In this situation, you need to buy either an expensive septic tank with an intermediate storage tank, or connect to a centralized collection pipe to drain sewage.

In this case, the sewage system is built from two branches. The first is dirty water from the steam room and shower, it can be discharged into a water well-gate or a collection container, and then run through another pipe by gravity into the main part of the sewer. The second part is sewage drains from the toilet and the bathing department, the kitchen, if there are any in the bathhouse.

Please note that the water drains from the steam room are a separate sewer part, it does not need to be connected to the first one, since it will not be possible to get rid of the awful smell in the bath.

In any case, there must be an intermediate tank between the sewer outlet from the bathing compartment and the steam room, which serves as a water seal.


To properly make the sewerage in the bath, use the prefabricated drainage arrangement. In fact, this is a large container that is connected to the drainage bath sewer. There are a lot of options for the execution of a ballast or prefabricated accumulative waste system. Most often it is an insulated container, which is dug into the ground, divided into two sections, or assembled from a pair of separate polyethylene tanks. If you choose the primitive option, this is a cesspool, in which the walls are lined with brick and covered with asphalt-bitumen waterproofing.

The upper part is covered with a stove, in which the drainage waste from the sauna room is connected. Division into a pair of sections is required to settle solid and viscous components, the liquid part is poured into a nearby barrel and after cooling, and filtering is poured either into a septic tank or a drainage field. The collection of liquid is carried out either by gravity through the sewer pipes, or relatively clean water is pumped out by a pump into a drainage ditch.


In such a sewerage scheme, there are no devices (active) that will pump waste water from the place of the branch pipe for draining the bath to the accumulation pit. Most often we are talking about a plastic tank, which is connected to a drainage water dispersion system in the ground.

If the cottage is located in a remote and remote area, then the bath box is installed at a distance from the building, but only higher up the slope, if there is one. For perfectly flat areas, the bath box must be lifted on piles or installed on a columnar base. 0. 5 meters height above the ground make it possible to carry the collecting tank at a distance of almost 10 meters.

Stock movement occurs by spontaneous drainage, and therefore, for the normal functioning of the sewage system, 3 conditions must be met:

  1. Pipes must be located at a slope of at least 5%, if the water goes through the gutters, then 3% below the level is enough.

    In reality, the slope will be greater, because non-pure water is discharged from the bath complex through the free-flow sewage system, and almost always deposits on the surface of the walls do not allow the drain in liquid form to drain normally.

  2. There should be no deflections or "elbows" in the drainage structure through self-draining, in which water can begin to collect. Sometimes this is due to soil subsidence, and then there is a risk of pipe clogging.
  3. Be sure to produce mechanical protection and pipe insulation.

Please note that the principle of self-draining does not make it possible to lay sewers deep in the ground, as a rule it is 0.

5 meters, no more. If you drain water from a bath in frost, then in a pipe, which insulated warm or hot water will quickly heat up the walls, which means that the risk of ice plugs is minimal.

Sometimes the owners of a small summer cottage bath do not particularly bother with laying pipes and arranging a pit. If the bathhouse is mounted on piles, then a 200 liter plastic horizontal barrel is installed in the space between the underground and the ground. This is enough to collect wastewater after visiting the bath for 3-4 people.

In the lower part of the barrel, a fitting with a tap is embedded, a hose is connected, which performs all functions. All dirty water will be collected in the barrel by gravity, and at the end of the rinsing, it is enough to throw the hose into the nearest ditch and open the tap. After 1/3 hour, the container is empty.

Naturally, the drain from a bath into a simple barrel is not so convenient due to the fact that there is no drain for the toilet. But a simple system has a lot of advantages:

  • Minimum spending on the equipment of the bath sewerage.

  • The drain system can be easily serviced and repaired, and at the end of the summer season can be removed or even removed from the site.
  • There are no unpleasant aromas that always accompany drain pits.

For a home stationary bath, self-draining sewers are used only when the pipe is connected to a central waste collection system. In other cases, pumping systems are usually used.

How to make a sewage system in a bath with your own hands

Arranging a system for draining used water is exactly the case when 99% of the work can be done with your own hands and at a high level of quality.

most modern sewers are assembled from ready-made elements and assemblies, and therefore the process of arranging a drain in a bath is not much more difficult, it takes weeks to assemble a children's designer. But in some cases, professional soldering equipment may be required.

Selection of the type of sewerage system

The principle of selection is the simplest - the complexity and possibilities of the sewerage system must necessarily correspond to the price of the bath itself.For a small bath, which is built into the house, a simple solution would be to connect the drain through a water seal to the central sewer pipe.

For a summer cottage bath complex, it may be the best solution to install a barrel to collect liquid.

Solid bath buildings on an insulated base require the installation of a pressure system for drainage.


An approximate scheme for arranging a pressure system for removing dirty water is below. The main elements are a pump and a storage tank, all the rest will be selected after the fact at the end of the bath construction. You also need a well-revision, valve attachments and sewer pipes.

The study of the site geologists and the planning of the scheme for diverting runoff water

Naturally, usually the place for the construction of the bath is chosen and does not think about the need to complete the construction of the sewage system .

.. Usually, the bath is installed at a distance of 5 meters from a residential building or the main building.

Good advice! If you have the opportunity, then plan the location of the bath below the house level, and best of all at the end of the site. In this case, you can connect to an existing chimney without the risk of disruption or blocking of work.

Why is geology important? In pressure systems, pipes and containers are laid in the ground, to a depth not less than the level of freezing. Moreover, the viscosity, density and tendency to the ground to heave determine the design of the container for collecting waste water. In order to determine the nature of the soil, you need to drill a diameter of 2 cm with a hand-held motor drill at a depth of at least 2 meters. The release of the rock will show what exactly will lie at the site of the sewer construction.

How to make a drain hole

If there are heaving soils in the area of ​​the bathhouse construction, you will need to dig a pit.

For an average bath, it will be enough to make a container with a volume of 2 m 3 , for a small steam room, it will be enough to install a plastic tank for 0.8 m 3 . For sewage, special models are sold with a wide removable type hatch with clips. Digging can be done manually or with a mini excavator. The walls must be aligned vertically, and the bottom must be compacted with tamping and covered with a gravel-sand mixture.

Then make a concrete screed with a fiberglass tape or twig. The joints are made of bricks, and the thickness of the masonry is at least 25 cm; polyethylene flanges are installed at the points of outlet of sewer pipes. The left wall is perforated for water discharge. Inside, lay out a partition with a height of at least 1.2 meters.

At the end of the work, the inner surface is fused with glass roofing material. Putting a plate on top, and most often from technical polyethylene.

Installation of an internal sewerage system in the bathhouse

Manufacturing of sewerage for a bath in the country It is required to dig a trench and plan a pillow under the pressure pipe.If the height difference between the collection tank and the inspection well is less than 1 m, then simple non-pressure plastic pipes can be used, which are assembled on rubber seals.

In other cases, it is required to lay and weld polyethylene pipes with a diameter of at least 8 cm.

The connection from the drain inside the sink and bath is carried out with the installation of a water elbow, which will block the gases that accumulate inside the tank. Waste water must be drained inside without contact of the pipe with the surface of the liquid in the container.

Place a pump in the adjacent compartment and adjust the float level. To check, fill the system with clean water and pump it along the entire sewer line, if there are no leaks on the walls and pipe connections, then you can fill the pipes and wall sinuses with insulation, expanded clay or burnt clay, and then cover with a soil pillow.


Drainage can be done in the bathhouse in 4 days.

Such a water collection system can be made in 1 day, with less material costs. Naturally, the level of comfort is important, but the installation of a pumping sewage system does not always justify the money spent. Perhaps, the use of differences in the relief of the site makes it possible to save money and solve the problem of removing waste water through a self-draining sewage system.
