PURPOSE: A rainwater and sewage drain system is provided to reduce excavation work for forming a pipeline and implement an efficient structure considering the characteristics of rainwater and sewage pipes. CONSTITUTION: A rainwater and sewage drain system comprises a drain way(10), a rain water inlet part(20), and a sewage inlet part(30). The drain way includes a rainwater channel(a) and a sewage channel(b) for separate flow of rainwater and sewage and a sewage channel closing part for closing the top, bottom, and lateral sides of the sewage channel. The rain water inlet part is formed in the drain way so that rainwater flows through the rainwater channel. The sewage inlet part is formed in the drain way so that sewage flows through the sewage channel. |
