I thought, thought, how best to equip the country sewage system and, it seems, found the perfect solution.
Let me remind you that my task is unusual: somewhere to drain a very small amount of waste from the toilet in the country: 100-200 liters per year (Reflections on a septic tank).
I realized that there was no need to clean these drains. It is much easier to pump them out with a sewer truck every few years.
At first, I considered as one of the options some kind of cheap plastic septic tank with a plugged outlet and the assumption that everything would pour there, and then pump it out. It turns out that this cannot be done: any plastic septic tank must always be filled with water or drains, otherwise it will float up or its body may physically break.
I began to look at plastic storage septic tanks (in fact, it's just a barrel buried underground). I chose the smallest "Termite Underground capacity 0.7" for 17,600 rubles.
I called and found out about the installation. They said that the installation costs 18,500 rubles, but three cubes of sand are still needed (5,000 rubles) and a concrete slab or pouring concrete into the bottom of the pit is required so that the capacity does not float up (another 10-15 thousand). In total, more than 50,000 rubles for some kind of plastic 700-liter can.
And then I realized that I was walking on some wrong path. :)
First I came across a super-cheap solution - second-hand eurocubes. This is a 1000 liter plastic container in a metal frame.
For a cesspool, an unwashed eurocube for 2500 rubles will do. The problem is how to bury it in the ground so that it does not deform. Some people beat them with boards, but they say that groundwater still deforms an empty cube, pressing on it from the outside.
Finally, I found a solution that now seems ideal to me: why bury a soft container under the ground and protect it from deformation, if you can immediately bury something that is not subject to deformation - concrete rings.
I think for my purposes such a KSD 10-9 ring with a bottom will be quite enough. It holds about 700 liters and costs only 1,650 rubles.
Top cover with a hatch (600 + 1000 rubles).
Total, plus delivery plus digging and installation, about 20,000 rubles.
You can add a second ring, there will be not 700, but 1400 liters.
I found a company that is ready to do everything on a turnkey basis for 25,000 rubles with one ring and 30,000 rubles with two.
The main question is how realistic it is to make this concrete container airtight and not to pour ground and melt water into it. If tightness is realistically ensured, the ideal cesspool will be cheaper and better than plastic bullshit.
