FIELD: sewerage systems.
SUBSTANCE: construction of sewer systems and sewage wells. The storm water inlet consists of a body (1) and a cover (2) with holes for water passage, each made in the form of a single pressed structure from a polymer-sand composition, consisting of 20-30% polymer and 70-80% sand and equipped with a metal reinforcing cage. The lower part of the cover (2) of the storm water inlet is covered with a layer (7) of an elastic polymer. The mass fraction of the metal reinforcing cage of the cover (2) is 20-25% of the total mass of the storm water inlet cover.
EFFECT: increased strength of the storm water inlet and increased service life.
