The surface of the septic tank cubic containers: their own hands
Self-made and effectively working LOS (local treatment facilities) cause an increased interest from our portal. For example, it is often used in low groundwater table three-chambered septic tank of concrete rings.
Attempt to implement this scheme on poorly draining, heaving soils, with a high level of groundwater can result in failure. Rings may shift in seasonal shifts soil and leakproof septic tank and drainage well (without the bottom of which is placed), or field of filtration, is constantly flooding. Use of water-saturated for "problematic" portion purchased plastic sewage plants may also lead to the fact that when heaving soil to bury the system compresses or pushes the wall.
In this connection, interesting circuit implementation surface of the cubic containers on septic "swamp" the user with the nickname FORUMHOUSE Globi.
Globi (Member FORUMHOUSE):
I'm in a high groundwater level. Ordinary septic tank do. Looking at the neighbor's ordeal (he was the second season after the winter trying to "drown" all the time pop-VOC), I decided to do a surface treatment system on the basis of 2 cubic containers.
The system has attracted attention of users faced with the same problem of high groundwater level. But, determined to build this circuit, you should immediately think about where to take stock after the septic tank. Often the problem of after-treatment and recycling of "black" water in a swampy area, with a lack of absorptive capacity of the soil, turns into a real "headache".
To learn how to solved this problem Globi, we will tell a little later, and now describe constructive surface septic tank. To build it, we will need:
- Evrokuby - 2 pcs.
- The material for the construction of additional building to the house in which is mounted a septic tank: boards - 10 pcs. section 100h25 mm flat sheet 1 cm thick slate.
- The material for the insulation box - polystyrene (polystyrene) - 10 sheets.
- Profiled roof "house" for a septic tank.
- Melochovki - sewer pipes, special seals for septic tanks, tees, hardware.
Globi:
Evrokuby cost me 3,500 rubles per 1 pc. (At 2012 prices). For the material for the "sarcophagus" I gave more 4100 rubles. Pipes and bends have cost 3500 rubles. + Every melochovki and building materials in the form of a hollow concrete block, cement, metal mesh for reinforcing the base under the septic tank. For everything I've spent about 17 thousand. rub.
The design of additional building may be changed according to the size and accessibility of the septic tank or other building materials.
The main thing - the surface mounting the septic tank, keep in mind that all the plumbing connection point - toilet, sink, bath - should be higher than the point of entry into the tank.
There must be a slope of sewer pipes (2 cm to 1 meter, with a diameter of 110 mm). If the height of the ceiling of the first floor (from ground to floor) does not allow to stand slope road, the I have to think about how to "throw" waste products into the septic tank, for example, with the help of fecal pump.
Process septic mounting clearly visible on these photographs.
Fill the concrete foundation, and are conducting further installation of the system, do not forget at the end of the assembly to check it on tightness to make sure that after the launch of a septic tank will not "smell" when near house. For this Globi compressor motor used previously drowning out the standard plug and the input plug set with the nozzle of the accumulator.
Globi:
Shaking his long, until one of the plugs is not taken off with a loud bang. tight system outsider odor should not be. Next, I will mount the vent pipe, and consider how to make the ventilation of the boxes that due to overheating in the summer in septic tanks are not killed bacteria.
Checking pressurized containers for leaks, important not to get carried away by the process, or a plastic cube can break.
For the construction of the system need to understand the principle of its operation. According to the user said he thoroughly rummaged through the Internet to learn about the nuances of the basic functioning of the septic tank. The basis of the whole system - the right device overflows, cubic containers from one another, and further the discharge of effluent into the drainage.
On admission in septic waste, they are separated. Part of the solid waste goes immediately to the bottom or precipitate over time, going through sedimentation. The liquid is then poured into the next tank. In this case, the liquid in the tank following the previous cube should be taken away so that the overflow was one third below the level of the water surface in the tank. This will allow to cut floating on the surface of solid inclusions.
Globi:
From the classical modulations schemes, I retreated. This will save on the tassel. In principle, they are not needed. Because septic zaglublon not, at any time, you can still disassemble and clean the pipe.
For example, in the design of the entrance to the septic tank is cleaned from home. For this audit should hatch. The overflow between the first and the second capacitance is also available, it is enough to remove the wall (slate sheet, screwed on the screws) and detach the adapter to a ventilation tube.
Output from the septic tank is cleaned out - sanitary rope through a tee.
You also need to ensure proper ventilation of the septic tank. For this installed sewer pipe (It is output as high as possible, e.g., to the ridge) and the inflow pipe that provides air flow into the system. This tube is usually made at the end of the filtration / aeration field in a drain pipe.
The sewer pipe provides communication sewer system to the atmosphere, and prevents the unpleasant smell in the building and hydraulic locks stall.
One of the main elements of the system - drainage tunnel. User made it out of the old baths, bury at a depth of 0.5 meters. He put it on concrete blocks (around the perimeter) to increase the volume of homemade Infiltrator - inverted container without a bottom. Top bath is insulated with foam and covered with earth. Entering through drain hole in the bath.
Globi:
Operation showed that drainage does not freeze.
Another question that troubled many who decided to repeat the septic tank, if it freezes in winter.
Practice has shown that insulation foam box 100 mm in thickness is sufficient for normal operation at low temperatures. It should be borne in mind that the wall of the house, to which application container, warm. When the activity of bacteria (fermentation) generates heat. Extras (just in case) the user has set the bottom, with the right side of the tank, the electrical heater power of 0.5 kW. During operation even at -18 ° C a septic tank has not frozen, and the heater really only in extreme cold.
To increase the efficiency of the cleaning system Globi launches her purchase Bioactivator - microorganisms, flushing them down the toilet once a month.
Another question - will there be enough volume of 2 cubic containers or better put 3 pcs.
Globi:
The volume of the septic tank depends on the number of people living in the house. In addition, there are various evrokuby volume. My - 700 liters. Effective Amount - 550 l each. Total - 1100 liters. This, of course, a bit not up to standards recommended for 2 people, especially if there is a volley reset, but in my house is worth 2 bathrooms - with compost and composting toilets, and a shower with its own drainage. If need be, over time, it will be possible to put 2 more cubic containers. It's easy, because dig does not have to.
One of the key advantages of the surface of a septic tank - its scalability, upgradeability and ease of maintenance.
Also give an example of the calculation of the required volume of the septic tank. If you take the simplified scheme, then at a rate of water flow for 1 person per day need 200 liters. Multiply this figure by 3, because you must defend the runoff for three days. Next, multiply the result by the number of people living in the house. For example, for two people is required septic useful volume of 1200 liters (200h3h2 = 1200 l).
This takes into account the correction factor - 1.3 (1200h1.3 = 1560 l) since septic volume part is not involved in the cleaning process, and possible force majeure - the arrival of the guests, a massive discharge of water, installation of additional plumbing and etc.
According to our portal users, the volume of the septic tank can not be less than 2.4 cubic meters. m, as water consumption usually increases the weekend (washing, bathing, swimming), and in a possible increase in households in the future, we already have a margin of septic tanks.
And at the end of the article will tell you about new drainage versionThat the user has done.
Globi:
Filter cartridge, as in the photo above, I did learn from the experience of my friend, who operates her 10 years with a high groundwater table. Everything works without silts up anything, not frozen.
For the device used by drainage pipe wrapped in geotextile laid on the gravel (in this case of broken slate) cushion. Its depth - 0.6 m on top cushion covered with soil layer of 0.4 m and a flat sheet of closed slate, which provides an additional volume of air and prevents the washing of the cassette primer.. As a result, the area of absorption increased several times. Compare - 2Q. m Infiltrator first against 10 kV. m of new drainage.
