Creation of an autonomous sewage system: how to carry out the work and whether the choice of concrete rings justified itself

Due to the fact that my site is located outside the city, there is no sewer line nearby. I had to install an autonomous system designed to collect wastewater from my home. Before starting work, I had a dilemma, whether to purchase concrete rings for a cesspool or a special plastic container. My choice fell on products made of reinforced concrete, since they are more durable, they are not afraid of mechanical and physical stress, strong freezing of the soil.

I started the process of creating an autonomous sewage system with land works. I chose a place for septic tanks in accordance with the architectural design, at a distance of 20m from the residential building. Due to the fact that the concrete rings had to be immersed to a great depth, I brought in specialized equipment to prepare the pit.

At the same time, I myself dug trenches for laying sewer pipes from the house to the cesspool. The pit was immediately prepared for two wells. I took the advice of my acquaintances, who operate their septic tanks in this way, while not spending money on pumping out sewage.

They work according to the following principle:

• from the house through the pipe comes drains from plumbing rooms, kitchen;
• in the first well, the solid fractions settle to the bottom, and the liquid, as the well is filled, flows through the built-in pipe into the adjacent septic tank;
• in the second well there is only liquid, which gradually goes into the ground.

To lay the rings (each well consists of 3 fragments), a crane had to be called in, since, due to the large weight, these works cannot be done manually. On top, I installed concrete covers with holes for hatches, which are closed with plastic covers.
