FIELD: construction.
SUBSTANCE: plant contains at least one collection tank for mechanical impurities with at least one separating sieve located inside it for waste water passing through it and containing mechanical impurities. The sieve divides the collection tank for mechanical impurities into the area containing mechanical impurities and the area free from mechanical impurities. The separating sieve through the hinge is rotatably connected to the flange of the collecting tank for mechanical impurities. The sieve, at least in the edge area remote from the hinge, has at least one opening open from the outside.
EFFECT: effective sieve cleaning by means of washing with pre-treated wastewater.
