【正文】 asin. According to building nature, purpose and construction unit requirements, has improved the indoor water supply and drainage sanitation systems. The building requires fire water system is safe and reliable, set up a separate fire hydrant system and automatic sprinkler system, fire pump fire when started directly. Living water pump can be started automatically according to user needs, and automatic voltage regulator. The design manual contains architectural engineering design life, water supply, fire water, rainwater, sewage and other design projects. The main contents include domestic water supply system design calculations, design hydrant water supply system calculation, design sprinkler system calculation, design calculations sewage drainage system, roof drainage system design calculations. KEY WORDS: domestic water supply， Fire Hydrant， automatic sprinkler system， building drainage 2020屆給水排水專業(yè)畢業(yè)設計 1 目 錄 摘 要 .......................................................................................
