Septic for bath itself: types
When building a bath, it is important to determine the wastewater treatment. Sewage must pass a certain filtration, and only then get into the environment. If you do not plan to do a toilet in the bath, then a septic tank can be made with one camera. And if the sewage will merge into the sewage, then install two tanks, one of which must be completely sealed.
Location and construction
Choosing a place for the construction of a septic tank, it is necessary to provide for the access of vehicles. Whichever system you use, periodically it will be necessary to extort accumulated impurities.
Regardless of the number of containers in the future septic tank, it is necessary to determine the materials used. Such constructions can be made from:
- metal barrel without bottom;
- plastic container with drilled holes;
- reinforced concrete rings;
- old car tires.
The choice of design will depend on the quality of the soil at the site, the depth of the groundwater and the volume of simultaneously discharged water. The first tank (or only if the toilet in the bath is not provided) should have time to pass through all the incoming drains.
If you use a metal barrel, a small plastic container or eurocubes, then the site should be sandy soil. It will absorb water well and the container will not overflow. Also, groundwater should not come close to the surface, otherwise flooding cannot be avoided.
When using reinforced concrete or monolithic rings, and also tires, the volume of a septic tank turns out much more. This design can be used on virtually any soil.
Of reinforced concrete rings
The use of reinforced concrete rings involves the involvement of technology. Such products weigh a lot, so you can not do without a crane. The device will look like this:
- The first tank (the largest) is made completely airtight. It will defend drains. After filling, the liquid through the pipe installed in the upper part flows into the second tank.
- The second, not having a bottom, will play the role of a filter. It is made smaller. At the bottom, a cushion of rubble is constructed, 10–20 cm thick.
The number of rings in each pit will depend on the volume of one-time discharge of wastewaters and the depth of groundwater. The higher these indices, the deeper the well should be deepened.
In the first tank, the bottom and all seams are carefully sealed. This is necessary so that untreated sewage does not get into the ground. In the second pit, the seams between the rings can not be sealed.
Tip! If the bath is not provided for the presence of a bathroom, then you can get by with one pit. At the same time it is made unpressurized and with a cushion of rubble on the bottom.
We use old tires
Sewage using old car tires do the same as in the previous version. Everything will depend on the number of containers.
For the device septic used tires from tractors or heavy vehicles. They are large in diameter and the capacity will be sufficient. The pit itself for laying tires needs to dig more, by 10–15 centimeters. After laying the remaining space is filled with a mixture of rubble and sand and compacted.
The bottom of the first tank concreted or drowned out with a layer of silt. Also seal the seams between the tires. The second tank is leaking with a cushion on the bottom.
Do not forget the pressure cap. This detail will avoid unpleasant smell on the site. The installation of the ventilation shaft is also required.
Brick septic tank
You can build a single-chamber septic tank of brick. The main thing is that groundwater does not come too close to the surface. This option can be considered the most budget, because for the "construction" you can take the old brick, even non-integer. Here, the main thing, durability, but not appearance.
For the device of such a septic tank you need to dig a pit of the desired size. It can be alone (in this case, the partition between the containers is also made of brick), or separately for each container.
At the bottom, a cushion of sand is arranged and poured with concrete. For strength, you can spend reinforcement. The walls are laid out of solid brick. The width of the walls should be at least 25 cm, and partitions can be made "in brick".
If the tanks are located in the same pit, then for the second one there is no need to make a concrete floor. Then they carry out sewage from the bath to the first tank, and from it to the second one. An overlap can be made of a reinforced concrete slab or a concrete screed (how this is done can be learned by viewing videos from the Internet). Just do not forget to leave room for the hatch.
