Since fire and water have no mercy and the fire spreads quickly, it will endanger people’s life and property safety if unable to fully guarantee the quality of water supply and drainage for fire control. Scientific and rational water supply and drainage  system  for  fire control  can  effectively increase the efficiency and speed of fire rescue, reduce people’s property loss and improve  the  residential safety index of the building itself. In view of this, this paper mainly analyzes the characteristics and design key points of water supply and drainage engineering for fire  control  in  high-rise buildings.
