FIELD: sewerage.
SUBSTANCE: invention relates to sewage devices. Method consists in road contaminants washing out by water flow. Drain pipeline end section entering into storm drainage well is made in form of hollow cone, that is, nozzle, and arranged coaxially at leaving well discharge pipeline edge joint. Washout of road contaminations is provided in self-cleaning mode due ejector pump effect action in their joint zone between arriving rainwater flows of one of them outgoing from incoming drain pipeline and correspondingly another in form of water drain into drainage well from road surface.
EFFECT: providing for road contaminants washing out by independent self-cleaning as a result of dynamic interaction of incoming into it water flows from incoming sewer pipeline and water drain from road surface.
