Drain pit by one's own hands - technology

If the centralized sewerage system is not connected to the house, the problem of waste water disposal can be solved by arrangement of a drainage pit. At the same time, it is not necessary to spend time and money to order work in any construction organization, since it is quite possible to make a drainage pit with your own hands.

First of all, it is necessary to determine the volume of wastewater to be disposed of. It is from this that the size of the pit will depend. And it depends, first of all, on the number of people living in the house and the intensity of their use of various plumbing fixtures. If it is a permanently residing large family, then it makes sense to abandon a simple drainage pit in favor of a more productive and environmentally safe option in the form of one or a whole system of septic tanks. In addition, the drainage pit can not be used for any length of time without periodic cleaning by the forces of the sewerage companies. Accordingly, even at the stage of choosing the location of the pit, it is worth considering the possibility of a convenient access to their special equipment.

Drain Pit Having decided on the volume, you can proceed with choosing the location. For this, it is necessary to take into account the following factors:

  • depth of groundwater, which should not flow too high, since even the simplest waste pit necessarily requires at least a couple of meters of its own height;
  • of the range of the water source, which should be located no closer than 30 m from the future drainage pit;
  • the presence of a significant difference in heights on the site makes it necessary to place the pit in the lowest possible place;
  • to an apartment house can not be less than 2 meters.

Sequence of works on arrangement of the drainage pit

The first thing to do is to carry out a complex of earthworks. The best option is to use the excavator, but this is quite expensive and requires the possibility of driving the car to the work site. Therefore, the easiest way to dig a foundation pit with your own hands. With the help of ordinary shovels, several people are quite capable of bringing the pit depth to 4 meters. Such a significant depth is necessary in order to keep a reserve of space for pouring the drainage cushion from the layers of sand and gravel. Drainage is necessary here to prevent siltation of the bottom and worsen the operation of the drain pit. And in the case of an unsealed version of the pit, the layer of crushed stone should be increased. If a sealed structure is created, the bottom should be poured with a concrete screed.

Having finished with the bottom, you can go to the walls. A good option is the traditional technology of brickwork. Most of all for these purposes are full-bodied varieties of red brick. The brick is placed in a checkerboard pattern, which will facilitate the infiltration of drains from the drainage pit into the surrounding soil. From the outside, i.e. between the masonry and the walls of the foundation pit, either broken brick or crushed stone is filled, or old car tires are laid.

In addition, you can use ready-made reinforced concrete rings. Unload and stack them in their place in the excavation is most easily a crane manipulator. If it is not possible to provide the crane access, it is possible to build a self-made block hoist. In this case, the safety rules apply first, because the rings are massive enough to represent the most serious threat to those working with the sequence of ring laying:

- the ground is taken out to a depth of about one meter;

- the first ring is installed;

- the next ground meter is removed with careful control of the correctness of lowering the first ring;

- when the upper edge of the first ring is lowered by one meter, a second ring is set and the whole sequence is repeated;

- the slab plate with the hatch is installed;
