People who build or buy your house and want to do everything in your home improvement, including a large bathroom, toilet and of course the dream of every housewife huge kitchen. Faced with the problem of where to take sewer. Of course, you can buy ready-made factory septic tank, and you can save money and do it yourself. And how about this I want to tell.
First, you need to determine the location of your septic tank, usually on a hill, so as not to hit the water after the winter, when spring floods begin, and not too far from home, so by replacing the sewer tube sloped, it has not received a the bottom of the septic tank.
Secondly, you need to decide what material is your septic tank, but they can be made of concrete rings, which are used when doing well, and as can be covered with concrete, which also do themselves, and may be made of masonry. Of these three types and I will tell you.
If you decide to do with concrete rings, you'll need at least six rings, and a great option to be nine, and three sewer manhole. Then pour in the pit at the rate of deep, somewhere 2.8 meters in width, namely a diameter of rings and three meters in length so that the three rings of steel, one after another. Then drop the ring in three rows, in close to each other and one on one with the patch the joints, adding a solution of liquid glass there, so that the joints are not watertight. Do you get that ring peep from the ground twenty centimeters.
Then go to sleep the remaining space between the pit and underground rings. Thus, you will have three separate wells that you cover the hatches in the two wells, pour the concrete floor, that would not leave the water in the soil. Connecting a sewer pipe, breaking through the wall in the first well, where the pipe fits, and then doing spillover between this and the next pit twenty centimeters below the level of the incoming pipe, so that when typed into the well water, it did not go into the house. And do the same mobility between the second and third pit is also below the overflow level of the first ten centimeters. And all of a septic tank is ready.
But if you decide to make a septic tank made of concrete, then you have to dig the same hole. Make the formwork, to reciprocate into three equal parts of a pit to die after you have got three wells only square. Armiruete wall formwork nutria. Using a valve diameter of 10 mm and linking it to the grid ochkom 20h20sm. and releasing the ends of the earth reinforcement of ten centimeters, it is necessary for that to then when I'll fill in the septic tank cover, had a bunch of walls. And pour the concrete walls of the septic tank, which can be made most in the proportion of 10 parts of gravel, sand, 5 parts of cement, 3 parts, can be ordered. But if you prefer masonry, the walls of the septic tank can be laid with bricks.
When the wall dries, usually lacking a couple of days, dismantle formwork for walls and make the formwork for the cover plate must be minimum10sm. And do not forget to leave openings in the cover for manholes, somewhere 50h50sm. Armiruete cover the same manner as the wall while doing a bunch of fittings with ends that protrude from the tops of walls, and pour the concrete.
Continue doing input pipe and do play as well as in the first case, and welding yourself, or order the hatches on the embrasures, which turned out to flooded plate cover.
How does it work? You ask. Explains everything you send down the drain, the pipe enters the first well, and when the water will be typed to overflow, it overflows to the second well and defends. And when the second pit typed water to overflow to the third well, the water enters into the third well. And water is defended in the second well, she goes through the bottom third of the soil free of impurities.
