This building possesses for water draining water presses the high-rise construction to request for draining water to carry on the design. Unifies the actual situation, according to the building nature, the use, is equipped with the consummation with the room in for the water draining water sanitary equipment, concrete gives the drainage system design to be as follows: Water supply system: This construction underground to ground six by outdoor municipal administration pipe network direct water supply, the water supply system of seven to twenty-four is the water pump、the roof water tank and the reducing value joins. supposed two lead-in tubes. From different direction introduction. Both has safeguarded the water supply security, and saved the energy consumption. Drainage system: This design uses the dirt waste water parting emissions system. The tubing used had the shock resistance cast iron pipe waste. might further improve the environment quality for this. In the basement nearby the fire electricity stairwell, the pump house ground are equipped with the sump and the waste water lifting gear. Fire prevention system: This building fire protection rank belongs to the dangerous levelⅡThe level, the design content including the fire hydrant system
