I did not understand the sewage system absolutely. When it came to choosing a septic tank for a summer residence, I didn’t even know at first where to start, how to choose a durable and reliable sewage system for a private house. A friend gave contacts to the company Superseptic. I did not expect such a variety of models. I would be confused if it were not for the advice of engineers who helped to determine the expectations of the septic tank and chose the right one specifically for my conditions.
The fact is that I live in the Naro-Fominsk region, and there is a lot of water in the spring and it leaves poorly, the swamp stands until the summer. So, septic tanks are cheaper, such as Tank or Topop, are not designed for such loads (by the way, this is not just an advertising move, the company also sells these models, they are just designed for drier areas). Super septic tank Tver, which I just took, does not have electrics and electronics, up to 98% cleans drains due to a large number of filters, because of them there are no blockages. And there is no service, like Topas, for example. I am very glad that I turned to this company.
pros
good company, great septic tank
