PURPOSE: A drainage system using a water storage block is provided to prevent the soil of a slope from being washed away or collapsed and relieve drought by storing rainwater. CONSTITUTION: A drainage system(10) using a water storage block forms a slope with a water storage block(20) and comprises a drain block(30) in the lowermost part and a rainwater storage unit. The water storage block comprises a main body which is internally formed with an accommodating space and a cover for covering the main body. The cover is formed with an inlet hole. The lower side of the main body is formed with an outlet hole for discharging rain water flowing into the accommodating space. The rainwater storage unit collects and stores rainwater flowing into the water storage block in order to reduce the discharged rainwater to a river or a dam. |
