FIELD: construction.

SUBSTANCE: initial wastes from a collecting well 9 are uniformly distributed over receiving reservoirs 5-7 and then fed into distribution containers 22-24 from which they flow under gravity into a biological treatment apparatus 13. Groups of biological treatment apparatus are placed in depressed base slabs 19-21 lying on the same level. Biologically treated wastes come out of the biological treatment apparatus 13 through collector pipes 26 into a collecting well 27, from which they are fed into a reservoir 3. Water is decontaminated in an apparatus 34. Purified and decontaminated wastes come out of container 2 through pipes 36 and 37.
