The trunk road intersection or crossings, and the construction site were more likely to become the incident locations. Improper construction and aging were the main reasons for burst. The diameter of burst were concentrated in DN300-DN600, DN800 and DN1000. Cast iron pipe was more likely to burst. The probability of burst might increase when pipe age became 20-30 or 30-40 years. The burst was repaired in time.
