Laying of the drainage pipe
This pipe is laid during the foundation stage. It is located in the lower plane of the basement, with respect to the floor of the bath provides its slope. The pit under the septic tank should be excavated at a distance of 3 m from the basement of the bath.
The drain is laid as follows:
- The edges of the excavation should be reinforced - the formwork is installed and the walls are reinforced, or reinforced rings are installed.
- The bottom of the pit is filled with crushed stone to ensure the infiltration of waste water into the soil, and the upper part is equipped with an overlap with the supply for the
- pipeline. The sewage line must be straight to avoid accumulation of precipitation and formation of blockages.
- . When the drain and the water supply line are mounted, the bath floor is concreted with a slope inside of the
- piping The drain hole is equipped with a mesh membrane that will prevent clogging of the
- pipeline When the cement hardening process is completed, the tile that is covered is laid on the flooraetsya wooden bars, which make comfortable moving in the bath room. If it is right to organize work on the construction of foundations and the laying of floors, their insulation will not be required in view of the high thermal conductivity of the materials.
If it is ensured that the necessary slope of the drainage pipeline in the direction of the septic tank is not necessary to insulate it.
Layout of the drainage pit
Metal barrel as the basis for the septic tank. The drain pit for a bath of this design is very similar to the arrangement of drainage wells. To build such a tank, a barrel with a volume of 0.2 cubic meters is needed.
Construction instructions:
- Perforation is made in the walls of the barrel. With the help of a drill holes are cut, located at a distance of 15-20 cm from each other. The nature of the placement is chess.
- The bottom of the barrel is equipped with a branch pipe connected to the sewer pipe by a coupler connection, the place of entry of the branch pipe is sealed with silicone inside and outside.
- The drum is covered with geotextile material from all sides to ensure that large inclusions enter the tank and effectively drain the waste water.
- The geotextile is attached by strings or sticky tapes. When covering the surface of the barrel, it is necessary to ensure a tight fit of the material to its upper part, and also to leave the place of entry of the nozzle free.
Mounting technology:
- Earthwork for the construction of a septic tank is carried out in close proximity to the drainage site, the size of the excavation should be with some allowance for the size of the
- tank. A gravel cushion with a layer width of 20-30 centimeters is poured onto the bottom of the pit,branch pipe up.
- The pit is covered with crushed stone, the sewage system is brought to the device.
Drain pit for a bath of plastic barrels. Polyethylene tanks are also used for building septic tanks. For the construction of a two-chamber septic tank, two barrels will be needed: the first serves as a settling tank for sedimentation of solid and suspended particles, and the second is used as an additional filter.
Drains flow from the first chamber to the second through an overflow line equipped with a biological filter of sand and gravel, through which part of the water seeps into the soil. The lid of the barrels is impregnated with a biological protective agent and the tanks are closed.
To the septic of such a device it is necessary to connect gutters from different premises of the bath, which are connected to a collector that joins the septic tank with a tee. Also, it is necessary to equip the hatch for maintenance and repair of pipelines. The implementation of these recommendations will allow the construction of a durable and reliable sewage system.
A distinctive feature of polyethylene tanks used for the construction of a septic tank is the resistance of the material to external influences, so choosing its sewage system will be durable and reliable.
Filtration pads below ground
It is possible to equip the sewer with filtration fields, draining the entire area of the plot. The system consists of a network of perforated pipelines draining drains, a reservoir-distributor, in front of which a drainage pit for a bath with a dosage device is equipped.
Through a special pipeline, sewage passes through drainage pipes placed underground and absorbed into the soil. Pipes are laid at a depth of 0.8 to 1.5 m.but also take into account the level of occurrence of groundwater - between this mark and the pipe should be maintained a distance of at least a meter.
From the above options, you need to choose the most appropriate, in terms of both technical characteristics and material component. Proper construction of a sewage system for a bath will make the rest at the cottage comfortable and pleasant.
