When installing a septic tank, they reached groundwater

Good afternoon, yesterday they carried out the installation of a septic tank: 2 wells of two one and a half meter rings. So, when the tractor deepened by 2 m, water started, a rather strong stream, the pit quickly filled with water by 0.5 meters, I had to put the rings in the water. I consulted a lot with anyone, everyone unanimously claims that this is a class and I was lucky that I got into the water and the drains will fly into the pipe. In the morning I checked, the water rose a little and 15 cm remained to the first ring. So I think that things are bad, because winter does not melt away what will happen in spring and when we will live in the house ...

Hello, Sergey. The meaning of your appeal is not entirely clear, and yet let us analyze the current situation. Those who tell you “class,” to put it mildly, do not quite correctly interpret the situation. The fact is that with such a high level of groundwater, it is pointless to put a septic tank of filtration type from the point of view of efficiency and criminally, if we talk about the legality and moral standards. Your only way out is a sealed cesspool or the same waterproof two-chamber septic tank with the output of treated water to the filtration fields.

The latter can be equipped with 50 mm perforated polyethylene pipes. They are laid below the freezing depth of the soil, and the effluent is supplied using a pump septic tank installed in the second chamber. Automate the process of pumping purified water using a float valve.
