A comment
I decided to make a septic tank from European cubes, involuntarily underestimating the location of the overflow pipe. Being lowered to the bottom of the chamber, the entrance was constantly clogged with feces and other waste products. After a little thought, I moved the pipe to the center of the cube, thanks to which I was able to radically improve the design.
Only 2 people permanently live in the house, while on the weekends three more come to visit. The system copes with the base load and with sharp water hammer caused by a twofold increase in runoff.
pros
unpretentious design
a crust thicker than 30 cm is not formed,
bottom sludge is practically not formed.
Minuses
the possibility of clogging the overflow pipe,
It’s forbidden to throw paper in the toilet because of the risk of clogging,
the reliability of the system raises questions because of the need for concrete walls - concrete does not tolerate temperature extremes.
Term of use
more than one year
