Actually, to the very construction of the septic tanks "Dochista", the majority of summer residents have no complaints. However, sometimes the quality of the installation of this equipment is censured. Firms that carry out this work often make it hastily and without the proper technology. For example, the entrance of the pipe to the first compartment can not be sealed, as a result of which, during operation, groundwater enters the tank inside the tank. In addition, installers may incorrectly fix the pump, etc. However, the "Dochista" septic tank is good enough that it can be easily installed independently if desired.

Where to mount

First of all, of course, it is necessary to determine the place of installation of the "Dochist" model. The septic tank of this brand is mounted in compliance with such recommendations:

1. The tank must be installed below the foundation.
2. The optimal distance from the house to the septic tank is 5 m. In any case, it is not recommended to install a tank farther than 15 meters from the building wall. Otherwise, the external mains will often be clogged. If there is no possibility to dig a tank at this distance, the pipe must be equipped with an intermediate pit.
3. Choose a place for a septic tank should be in such a way that, if necessary, it could easily be reached by a sewage machine.
4. Any motor transport over the buried septic in the subsequent ride should not.

Installation procedure

Next, let's see how, in fact, the installation of such equipment as a septic tank "Dochista" is being made. Installation of it begins with digging holes. When carrying out this procedure, it is taken into account that the manufacturer does not recommend that the tank is more than 1 m deep (from the zero mark of the ground to the top). The optimum indicator of the depth of the hole in most cases is 150-170 cm. A sand cushion is poured onto its bottom. The walls of the pit are concreted. Further digging a trench under the highway to the house. The walls of this ditch can be strengthened with wooden formwork. The diameter of the pipeline should be 110 cm. It should be laid at an angle of at least 20 mm per running meter.

Pit under the infiltrator is excavated at a distance of 2-15 meters from the wall of the septic tank. At its bottom pour 30-40 cm of rubble. Trench under the highway between the septic tank and the infiltrator is also excavated at an angle of 22 mm per running meter. After installing the drainage tunnel, it is connected to the tank and the vent pipe is mounted on the other side. Further, the infiltrator is covered with sand approximately half a meter thick. On top of the insulated heater. It can be, for example, expanded polystyrene. Then the pit is covered with soil to the top.

The septic tank is connected by a highway with the sewage system of the house and the pit is covered with a lid. On top of her stack insulation. At the final stage, a backfill is made.

The above method can be used when installing equipment of all modifications. This is how the septic "Dochista" H5 is assembled, the reviews are also good, the H-7 and 9 models, the "R" and "S" tanks.

Filter well

If the groundwater on the site is low, instead of an infiltrator for additional treatment of sewage can be arranged a special well. It represents an ordinary deep pit with reinforced plastic or concrete rings of walls. A well is being dug out a short distance from the septic tank. The pipe in it must also come in at an angle. The bottom of the pit is not concreted, but covered with rubble, a thick layer, at the final stage the well is equipped with a vent pipe, covered with a lid and sprinkled with soil.

Mounting rules

"Dochista" is a septic tank, with the installation of which the following recommendations are observed:

1. Use a special technique for backfilling the tank or tamping the soil above it.

2. In the event that the groundwater in the site is too high, the bottom of the pit under the septic tank should be concreted. The tank itself in this case is fixed in it with special clamps.

3. All joints between the elements of the resulting cleaning system are necessarily sealed. To do this, you can use special cuffs or a usual bitumen solution.

4. The width of the trenches should be such that on both sides of the laid pipes there were at least 20-30 cm of free space.
