I made a septic tank with the most useful volume. Why pay for extra, useless space?

Burying a bunch of concrete rings under a septic tank in the ground, not everyone understands which part of them will actually work, and not just lie in the ground.

When I started this whole story with the construction of a septic tank with my own hands, one of the main criteria for me was the minimum budget.

Read the entire background in the articles, on my channel.

Most of the materials for its construction (reinforcement, crushed stone, sand, etc.) I already had. But in this case, I did not want to overspend.

Therefore, the design of my septic tank is as useful as possible.

I was counting on the fact that all the content will go almost to the top, as much as possible.

• First, the concrete box is buried deep. That is, after the end of the work, it will completely hide under the ground.

• The pipe from the house goes at the very top of the working part of the septic tank.

• Overflowing, from the first compartment to the second, slightly lower than the entrance to the septic tank, but also almost to the ceiling.

• Well, overflow into the filtration field using a pump, through a HDPE pipe.

And I also made an emergency drain, in case the pump does not work.

Thus, there is nothing superfluous.

A rectangular container "1.8 x 2.3 x 0.8" meters (this is a pure internal volume), divided into two parts, will almost completely work.

But you can't just pour the lid on top and bury it, you need access.

To do this, it is enough to make outputs, but small in size, which will save the budget.

But more on that in the next articles ...
