A comment
My story is this: installed the Septic tank Dochista S series in the country. He put it himself without resorting to the help of installers. There were no problems with the installation, a clear instruction does not give the right to make an error. It took almost 10 days to install, but this is all the supporting work (a well, piping, digging a pit). Maintenance and operation do not cause problems and serious financial costs. I bought a model H (it is more productive) and installed it in a private house of my parents. Again, the installation was carried out by himself with the involvement of a couple of friends. All done for 5! For days it was even faster, they did not begin to order special equipment for digging a pit. The family is large, there is a lot of water every day and the septic tank is steadily coping with the load.
