Septic from Eurocube do it yourself

The arrangement of sewage systems in a private house has become a noticeable trend. For the device septic tank often used eurocubes. In this article we will consider the installation methods of such septic tanks.

Septic from Eurocube do it yourself Eurocubes

The Eurocube is a cube-shaped container made of multi-layer polyethylene. It is designed to store various liquids. Its advantages over a septic tank of concrete rings or an excavated drain pit are as follows:

  • no odor;
  • the ability to organize the system yourself;
  • quick cleaning of the septic tank;
  • Long service life.

When designing a future structure, it is necessary to determine the size of the plastic container. It depends on how many tenants live in a private house.

You can estimate the cost of water per person per day by multiplying them by the number of tenants. The size of the septic tank should be 2-3 times larger than the obtained value.

For example, if the final value is 1700 liters of water, then two containers of 1 thousand liters each will be required.

It is necessary to have a septic tank no less than 30- 40 meters from the well.

Also, it should not be too far from the foundation of the house. The ideal option would be its placement in 5 meters from the building. For the flow of wastewater into the septic tank, it is necessary to observe the correct pipe slope. And if the distance from the house is too large, it will force to put the Eurocup in the ground even deeper than originally intended.

For the organization of a complete cleaning system requires the creation of a drainage area. There will be water from the European cup after processing. To do this, prepare a trench with a length of several meters, diverging from the outlet. A sand and gravel cushion is being prepared in the ditches, pipes with perforation are laid, and the top is covered with rubble, geotextile and soil. Read more about creating a filter field here.

The plastic from which Eurocubes are made is fairly light, it can undergo deformation due to seasonal soil heaving. To avoid such problems, it is required to concrete the bottom of the hole in the ground.

The width and depth of the trench should be equal to the size of the Eurocup + 15 - 20 cm on each side. From the house to the installation site, trenches should be prepared for the drain pipes with a slight slope. Ditches should be provided with a pad of sand and gravel to reduce the possibility of pipe deformation. Learn more about the technology of laying pipes and installing septic tanks here.

Stages of manufacturing and installation work

  1. First, you need to carefully calculate the volume of containers that will be installed.
  2. Preparation of trenches for Eurocubes includes not only digging to the required depth, but also pre-concreting the bottom of the holes with the creation of a sand-gravel cushion for drain pipes.
  3. If the septic tank contains more than 1 container, you need to prepare the connecting pipe and seal it properly with silicone or sealant. The second auxiliary eurocube should always be set 20-30 cm below the first. The opening for the connecting pipe in the first euro cup should be 20-30 cm below the inlet for the drain pipes.
  4. When assembling, it is necessary to arrange ventilation openings and openings for future cleaning in each used container. To do this, a hole is cut in the upper part of the cube, into which a pipe with a diameter of about 5 cm is inserted.
  5. Before installing the containers, leading the pipes and sealing them, it is necessary to reinforce the resulting structure. For this, metal frames for Eurocubes are used. They are welded together and lowered into the prepared pit. A concrete mix is ​​poured into a space of 10–20 cm wide left on the sides.
  6. However, such a construction is not considered complete without diversion of recycled waste to a dedicated drainage field. If there is no possibility to divert excess waste, then bioactivators should be used for the fastest processing of the contents of the septic tank.
  7. After the containers are mounted and strengthened, metal sheets or wooden shields are placed on top of the structure, which will prevent the likely ascent of plastic containers. Soil is compacted so that only the ventilation pipe is left free.

Plastic containers have thin walls; In order not to damage them, during the pouring of concrete, Eurocubes should be filled with water, and the process itself should be carried out as carefully as possible.


If ordinary treatment facilities require almost monthly pumping, for a septic tank made of plastic containers it may be necessary to clean it only once a year or even less often.This is due to the accumulation of unprocessed waste.

To clean this design, you need to clear the vent pipe from the ground and carry out the process of cleaning the container through it.
