About two years ago, the Mole 1.8 septic tank was installed. Since there was no experience in carrying out such work, and finances did not allow hiring a professional team, I made a lot of mistakes during installation and installation. To begin with, I installed drainage pipes on geotextiles, which is strictly not recommended. But the runoff after the septic tank goes practically without fine suspensions, so that for two years of intensive operation the soil did not “clog” the geotextile layer. On the filtration field, gravel was first poured then sand, as it turned out, it was necessary to do exactly the opposite. The exit from the septic tank was only forced with the help of a pump, the gravity was shut off, but the system coped well with the drains and the level in the tanks did not rise. In general, with all the mistakes made during installation, I have no problems with sewage.
