The present invention is to facilitate the manufacture, installation, maintenance and cleaning work by integrally forming the boundary stone and rainwater catchment to be installed to distinguish the road and sidewalks, the same shape as the road boundary stone to distinguish the road and sidewalks. A main body having a boundary stone provided at an upper portion thereof, and a main body integrally formed with a collecting hole for collecting external rainwater or wastewater at a rear lower portion of the boundary stone; An opening formed at an upper portion of the water collecting port to facilitate maintenance and cleaning, and a cover having a handle to disassemble and assemble at the opening; A drain port formed to protrude outward from the front lower center of the main body to discharge the waste water collected in the catch port through the discharge pipe; A wastewater inlet which is formed in the longitudinal direction on the drainage port and at the same time forms a catching jaw on the inside to allow external wastewater to flow into the catchment; The wastewater inlet is installed at the wastewater inlet, and the wastewater inlet can be provided with a wastewater strainer configured to be introduced in a state in which rainwater or wastewater is primarily filtered to prevent clogging of the drain.
